CVE-2024-20498 (GCVE-0-2024-20498)
Vulnerability from cvelistv5 – Published: 2024-10-02 18:23 – Updated: 2025-06-04 20:18

Summary
Multiple vulnerabilities in the Cisco AnyConnect VPN server of Cisco Meraki MX and Cisco Meraki Z Series Teleworker Gateway devices could allow an unauthenticated, remote attacker to cause a DoS condition in the AnyConnect service on an affected device.
These vulnerabilities are due to insufficient validation of client-supplied parameters while establishing an SSL VPN session. An attacker could exploit these vulnerabilities by sending a crafted HTTPS request to the VPN server of an affected device. A successful exploit could allow the attacker to cause the Cisco AnyConnect VPN server to restart, resulting in the failure of the established SSL VPN connections and forcing remote users to initiate a new VPN connection and reauthenticate. A sustained attack could prevent new SSL VPN connections from being established.
Note: When the attack traffic stops, the Cisco AnyConnect VPN server recovers gracefully without requiring manual intervention.

Title
Qemu: virtio: dma reentrancy issue leads to double free vulnerability
Summary
A double free vulnerability was found in QEMU virtio devices (virtio-gpu, virtio-serial-bus, virtio-crypto), where the mem_reentrancy_guard flag insufficiently protects against DMA reentrancy issues. This issue could allow a malicious privileged guest user to crash the QEMU process on the host, resulting in a denial of service or allow arbitrary code execution within the context of the QEMU process on the host.

CVE-2024-3187 (GCVE-0-2024-3187)
Vulnerability from cvelistv5 – Published: 2024-10-17 07:34 – Updated: 2024-10-17 14:40

VEX
Summary
This issue tracks two CWE-416 Use After Free (UAF) and one CWE-415 Double Free vulnerabilities in Goahead versions <= 6.0.0. These are caused by JST values not being nulled when freed during parsing of JST templates. If the ME_GOAHEAD_JAVASCRIPT flag is enabled, a remote attacker with the privileges to modify JavaScript template (JST) files could exploit this by providing malicious templates. This may lead to memory corruption, potentially causing a Denial of Service (DoS) or, in rare cases, code execution, though the latter is highly context-dependent.

CVE-2023-45679 (GCVE-0-2023-45679)

Title
Attempt to free an uninitialized memory pointer in vorbis_deinit in stb_vorbis
Summary
stb_vorbis is a single file MIT licensed library for processing ogg vorbis files. A crafted file may trigger memory allocation failure in `start_decoder`. In that case the function returns early, but some of the pointers in `f->comment_list` are left initialized and later `setup_free` is called on these pointers in `vorbis_deinit`. This issue may lead to code execution.

Mitigation
Architecture and Design
Choose a language that provides automatic memory management.
Mitigation
Implementation
Ensure that each allocation is freed only once. After freeing a chunk, set the pointer to NULL to ensure the pointer cannot be freed again. In complicated error conditions, be sure that clean-up routines respect the state of allocation properly. If the language is object oriented, ensure that object destructors delete each chunk of memory only once.
Mitigation
Implementation
Use a static analysis tool to find double free instances.
