CVE-2026-85234 (GCVE-0-2026-85234)

Vulnerability from cvelistv5 – Published: 2026-09-15 17:58 – Updated: 2026-10-08 09:13

Title
Tftp: tftp-hpa: denial of service due to out-of-bounds read/write in remap engine
Summary
A flaw was found in tftp-hpa. When the `in.tftpd` remap engine processes an inverse remap rule that also aborts with a non-empty custom error message, it can pass invalid match offsets to the `genmatchstring()` function. This leads to out-of-bounds read/write operations. A remote, unauthenticated attacker can exploit this vulnerability by sending a specially crafted request, causing the daemon to crash and resulting in a denial of service.

CVE-2025-26466 (GCVE-0-2025-26466)

Vulnerability from cvelistv5 – Published: 2025-02-28 21:25 – Updated: 2026-10-08 08:52
VLAI
Title
Openssh: denial-of-service in openssh
Summary
A flaw was found in the OpenSSH package. For each ping packet the SSH server receives, a pong packet is allocated in a memory buffer and stored in a queue of packages. It is only freed when the server/client key exchange has finished. A malicious client may keep sending such packages, leading to an uncontrolled increase in memory consumption on the server side. Consequently, the server may become unavailable, resulting in a denial of service attack.

Title
Gimp: gimp: heap buffer overflow in dicom export on oversized image dimensions
Summary
A heap-based buffer overflow was found in GIMP’s DICOM export plug-in. When exporting an image with extremely large width and height, the export path allocates a buffer using a 32-bit width * height (and bytes-per-pixel) product that can overflow. GEGL then writes the full uncompressed extent into the undersized buffer, after integer overflow in the allocation size

Title
Gimp: gimp: heap buffer over-read in x cursor (xmc) thumbnail loader on crafted file
Summary
A flaw was found in GIMP’s X cursor (XMC) thumbnail loader. When GIMP generates a thumbnail for a crafted XMC file, it allocates a pixel buffer using a width * height size computed in 32-bit signed arithmetic. If that product overflows, the allocation is smaller than the true image extent. A subsequent GEGL buffer read uses the unwrapped dimensions and performs an out-of-bounds read on the heap, after integer overflow in the size calculation. This can crash GIMP or corrupt process memory.

CVE-2026-106062 (GCVE-0-2026-106062)

Title
Gimp: gimp: heap buffer overflow in dds loader on crafted directdraw surface file
Summary
A heap-based buffer overflow was found in GIMP’s DirectDraw Surface (DDS) loader. When loading a crafted DDS image, buffer sizes derived from width, height, and pitch can be computed using 32-bit arithmetic that overflows. The allocated buffer is too small for the amount of pixel data written through GEGL, following integer overflow in size calculations. This may allow heap corruption and, in the worst case, arbitrary code execution in the context of the GIMP process.
Severity

Title
Sssd: sssd: denial of service via crafted passkey kerberos authentication request
Summary
A flaw was found in sssd. A local attacker can trigger a Denial of Service (DoS) by sending a specially crafted Pluggable Authentication Module (PAM) request when passkey authentication is enabled. Due to a missing state validation check in passkey Kerberos handling, the PAM responder dereferences an uninitialized pointer and crashes. This failure disrupts authentication services on the host.

CVE-2026-104039 (GCVE-0-2026-104039)

Vulnerability from cvelistv5 – Published: 2026-10-06 01:00 – Updated: 2026-10-08 02:40

Title
Sssd: sssd: denial of service via stale connection state reuse in pam gssapi responder
Summary
A flaw was found in SSSD. A local user can cause a denial of service (DoS) by disrupting system authentication services. When handling Generic Security Services Application Programming Interface (GSSAPI) authentication in the Pluggable Authentication Module (PAM) responder, cached connection state is freed upon completion without clearing the reference pointer. An attacker can exploit this by sending an additional request over the same connection, causing the service to access invalid memory and unexpectedly terminate.
Severity

Title
Sssd: sssd: denial of service via memory exhaustion in kcm responder
Summary
A flaw was found in SSSD. An issue in the Kerberos Credential Manager (KCM) responder allows a local user to cause a Denial of Service (DoS) by maintaining a persistent connection and repeatedly storing and destroying credentials. Because the service fails to release cached objects from memory when credentials are removed, memory consumption grows continuously, ultimately exhausting available memory and rendering the service unresponsive.

Title
Sssd: sssd: denial of service via out-of-bounds read in autofs responder
Summary
A flaw was found in SSSD. A local attacker can exploit this vulnerability by sending a specially crafted request to the autofs responder UNIX socket. Due to improper buffer offset calculation during request parsing, the service performs an out-of-bounds memory read. This flaw can cause the autofs responder process to crash, resulting in a denial of service (DoS).

CVE-2026-86345 (GCVE-0-2026-86345)

Vulnerability from cvelistv5 – Published: 2026-10-01 23:27 – Updated: 2026-10-07 20:19

Title
389-ds-base: 389-ds-base: starttls plaintext-buffer retention allows on-path attacker to forge an ldap client's authentication result
Summary
A flaw was found in 389-ds-base. The server does not discard plaintext bytes already buffered from a client connection when negotiating StartTLS, allowing an on-path attacker to inject a crafted LDAP message that is processed after the TLS upgrade and whose response is delivered to the client in place of the client's own pending operation's response, due to messageID collision. This can cause a client application to treat a failed authentication (bind) attempt as successful.
