RHSA-2026:14272
Vulnerability from csaf_redhat - Published: 2026-05-06 17:58 - Updated: 2026-05-07 18:08A flaw was found in Legion of the Bouncy Castle Inc. BC-JAVA bcprov. The `GOSTCTR` implementation is unable to securely process more than 255 blocks of data due to keystream reuse. This issue allows an attacker to break the fundamental confidentiality of any data protected by the `G3413CTRBlockCipher`, potentially leading to the recovery and access of encrypted data.
A flaw was found in Legion of the Bouncy Castle Inc. BC-JAVA bcprov. The `LDAPStoreHelper` implementation fails to properly neutralize special elements in user-supplied input before incorporating them into LDAP queries. This allows a remote attacker to execute an LDAP injection attack by supplying crafted input, potentially leading to disclosure of sensitive information or the manipulation of directory search queries.
A flaw was found in Legion of the Bouncy Castle Inc. BC-JAVA bcpkix. The PKIX draft `CompositeVerifier` implementation improperly accepts an empty signature sequence as a valid cryptographic signature. This issue allows a remote attacker to bypass signature verification mechanisms, potentially compromising the authenticity and integrity of data.
A flaw was found in Apache ZooKeeper. The ZKTrustManager component's hostname verification process can fall back to reverse DNS (PTR) lookup when IP Subject Alternative Name (SAN) validation fails. This vulnerability allows an attacker who can control or spoof PTR records to impersonate ZooKeeper servers or clients, provided they possess a valid certificate for the PTR name. This could lead to unauthorized access or manipulation of ZooKeeper services.
A flaw was found in Apache ZooKeeper. Improper handling of configuration values in ZKConfig allows an attacker to expose sensitive information. This occurs when sensitive client configuration values are logged at an INFO level in the client's logfile. This vulnerability can lead to information disclosure, potentially revealing critical system details to unauthorized parties.
CWE-117 - Improper Output Neutralization for LogsA flaw was found in Netty. A remote attacker could exploit this vulnerability by sending specially crafted HTTP/1.1 chunked transfer encoding extension values. Due to incorrect parsing of quoted strings, this flaw enables request smuggling attacks, potentially allowing an attacker to bypass security controls or access unauthorized information.
A flaw was found in Netty. A remote user can trigger a Denial of Service (DoS) against a Netty HTTP/2 server by sending a flood of CONTINUATION frames. The server's lack of a limit on these frames, coupled with a bypass of size-based mitigations using zero-byte frames, allows an attacker to consume excessive CPU resources. This can render the server unresponsive with minimal bandwidth usage.

RHSA-2026:14276
Vulnerability from csaf_redhat - Published: 2026-05-06 17:59 - Updated: 2026-05-07 18:08A flaw was found in Legion of the Bouncy Castle Inc. BC-JAVA bcprov. The `GOSTCTR` implementation is unable to securely process more than 255 blocks of data due to keystream reuse. This issue allows an attacker to break the fundamental confidentiality of any data protected by the `G3413CTRBlockCipher`, potentially leading to the recovery and access of encrypted data.
A flaw was found in Legion of the Bouncy Castle Inc. BC-JAVA bcprov. The `LDAPStoreHelper` implementation fails to properly neutralize special elements in user-supplied input before incorporating them into LDAP queries. This allows a remote attacker to execute an LDAP injection attack by supplying crafted input, potentially leading to disclosure of sensitive information or the manipulation of directory search queries.
A flaw was found in Legion of the Bouncy Castle Inc. BC-JAVA bcpkix. The PKIX draft `CompositeVerifier` implementation improperly accepts an empty signature sequence as a valid cryptographic signature. This issue allows a remote attacker to bypass signature verification mechanisms, potentially compromising the authenticity and integrity of data.
A flaw was found in Apache ZooKeeper. The ZKTrustManager component's hostname verification process can fall back to reverse DNS (PTR) lookup when IP Subject Alternative Name (SAN) validation fails. This vulnerability allows an attacker who can control or spoof PTR records to impersonate ZooKeeper servers or clients, provided they possess a valid certificate for the PTR name. This could lead to unauthorized access or manipulation of ZooKeeper services.
A flaw was found in Apache ZooKeeper. Improper handling of configuration values in ZKConfig allows an attacker to expose sensitive information. This occurs when sensitive client configuration values are logged at an INFO level in the client's logfile. This vulnerability can lead to information disclosure, potentially revealing critical system details to unauthorized parties.
CWE-117 - Improper Output Neutralization for LogsA flaw was found in Netty. A remote attacker could exploit this vulnerability by sending specially crafted HTTP/1.1 chunked transfer encoding extension values. Due to incorrect parsing of quoted strings, this flaw enables request smuggling attacks, potentially allowing an attacker to bypass security controls or access unauthorized information.
A flaw was found in Netty. A remote user can trigger a Denial of Service (DoS) against a Netty HTTP/2 server by sending a flood of CONTINUATION frames. The server's lack of a limit on these frames, coupled with a bypass of size-based mitigations using zero-byte frames, allows an attacker to consume excessive CPU resources. This can render the server unresponsive with minimal bandwidth usage.

RHSA-2026:11720
Vulnerability from csaf_redhat - Published: 2026-05-05 03:47 - Updated: 2026-05-07 04:30A flaw was found in Legion of the Bouncy Castle Inc. BC-JAVA bcprov. The `GOSTCTR` implementation is unable to securely process more than 255 blocks of data due to keystream reuse. This issue allows an attacker to break the fundamental confidentiality of any data protected by the `G3413CTRBlockCipher`, potentially leading to the recovery and access of encrypted data.
A flaw was found in Legion of the Bouncy Castle Inc. BC-JAVA bcprov. The `LDAPStoreHelper` implementation fails to properly neutralize special elements in user-supplied input before incorporating them into LDAP queries. This allows a remote attacker to execute an LDAP injection attack by supplying crafted input, potentially leading to disclosure of sensitive information or the manipulation of directory search queries.
A flaw was found in Legion of the Bouncy Castle Inc. BC-JAVA bcpkix. The PKIX draft `CompositeVerifier` implementation improperly accepts an empty signature sequence as a valid cryptographic signature. This issue allows a remote attacker to bypass signature verification mechanisms, potentially compromising the authenticity and integrity of data.
A flaw was found in io.quarkus:quarkus-vertx-http. A remote attacker can exploit an authorization bypass vulnerability by including semicolons, also known as matrix parameters, in HTTP requests. This allows bypassing path-based HTTP security policies, enabling unauthorized access to protected endpoints. The vulnerability arises because Quarkus's security layer performs authorization checks on the raw URL path, which preserves these matrix parameters.

RHSA-2026:11721
Vulnerability from csaf_redhat - Published: 2026-05-05 03:47 - Updated: 2026-05-07 04:30A flaw was found in Legion of the Bouncy Castle Inc. BC-JAVA bcprov. The `GOSTCTR` implementation is unable to securely process more than 255 blocks of data due to keystream reuse. This issue allows an attacker to break the fundamental confidentiality of any data protected by the `G3413CTRBlockCipher`, potentially leading to the recovery and access of encrypted data.
A flaw was found in Legion of the Bouncy Castle Inc. BC-JAVA bcprov. The `LDAPStoreHelper` implementation fails to properly neutralize special elements in user-supplied input before incorporating them into LDAP queries. This allows a remote attacker to execute an LDAP injection attack by supplying crafted input, potentially leading to disclosure of sensitive information or the manipulation of directory search queries.
A flaw was found in Legion of the Bouncy Castle Inc. BC-JAVA bcpkix. The PKIX draft `CompositeVerifier` implementation improperly accepts an empty signature sequence as a valid cryptographic signature. This issue allows a remote attacker to bypass signature verification mechanisms, potentially compromising the authenticity and integrity of data.
A flaw was found in the Apache Kafka Java producer client. A race condition in the client's buffer pool management can cause messages to be silently delivered to incorrect topics. This occurs when a message batch expires while its network request is still active, leading to premature buffer deallocation and potential reuse by other messages. Consequently, sensitive data may be exposed to unauthorized consumers, and data integrity can be compromised through deserialization failures and processing errors.
A flaw was found in io.quarkus:quarkus-vertx-http. A remote attacker can exploit an authorization bypass vulnerability by including semicolons, also known as matrix parameters, in HTTP requests. This allows bypassing path-based HTTP security policies, enabling unauthorized access to protected endpoints. The vulnerability arises because Quarkus's security layer performs authorization checks on the raw URL path, which preserves these matrix parameters.

RHSA-2026:13631
Vulnerability from csaf_redhat - Published: 2026-05-05 07:56 - Updated: 2026-05-07 04:30A flaw was found in Legion of the Bouncy Castle Inc. BC-JAVA bcprov. The `GOSTCTR` implementation is unable to securely process more than 255 blocks of data due to keystream reuse. This issue allows an attacker to break the fundamental confidentiality of any data protected by the `G3413CTRBlockCipher`, potentially leading to the recovery and access of encrypted data.
A flaw was found in Legion of the Bouncy Castle Inc. BC-JAVA bcprov. The `LDAPStoreHelper` implementation fails to properly neutralize special elements in user-supplied input before incorporating them into LDAP queries. This allows a remote attacker to execute an LDAP injection attack by supplying crafted input, potentially leading to disclosure of sensitive information or the manipulation of directory search queries.
A flaw was found in Legion of the Bouncy Castle Inc. BC-JAVA bcpg. A specially crafted PGP AEAD (Authenticated Encryption with Associated Data) message with an unbounded chunk size can lead to an excessive consumption of memory. This issue allows an unauthenticated remote attacker to cause memory exhaustion in a JVM, resulting in a denial of service.
A flaw was found in Legion of the Bouncy Castle Inc. BC-JAVA bcpkix. The PKIX draft `CompositeVerifier` implementation improperly accepts an empty signature sequence as a valid cryptographic signature. This issue allows a remote attacker to bypass signature verification mechanisms, potentially compromising the authenticity and integrity of data.
A flaw was found in the Apache Kafka Java producer client. A race condition in the client's buffer pool management can cause messages to be silently delivered to incorrect topics. This occurs when a message batch expires while its network request is still active, leading to premature buffer deallocation and potential reuse by other messages. Consequently, sensitive data may be exposed to unauthorized consumers, and data integrity can be compromised through deserialization failures and processing errors.
A flaw was found in io.quarkus:quarkus-vertx-http. A remote attacker can exploit an authorization bypass vulnerability by including semicolons, also known as matrix parameters, in HTTP requests. This allows bypassing path-based HTTP security policies, enabling unauthorized access to protected endpoints. The vulnerability arises because Quarkus's security layer performs authorization checks on the raw URL path, which preserves these matrix parameters.
