Pjsip

Heap overflow in PJSIP 2.16 and earlier DNS parser allows unauthenticated remote attackers to achieve code execution with no user interaction required. The vulnerability affects only applications explicitly configured with a built-in nameserver; users relying on OS resolvers or external resolver implementations are unaffected. No patch is currently available, but mitigation is possible by disabling DNS resolution or switching to an external resolver.

PJSIP versions 2.16 and earlier contain a heap use-after-free vulnerability in ICE session handling caused by race conditions between session destruction and callback execution, enabling memory corruption and potential code execution. This flaw affects all systems using vulnerable PJSIP versions for multimedia communication and currently has no available patch. With a CVSS score of 8.1, the vulnerability is remotely exploitable without authentication or user interaction.

PJSIP versions prior to 2.17 are vulnerable to a stack buffer overflow in the RTP payload parsing mechanism when processing more frames than allocated buffers can accommodate, enabling remote denial of service attacks over the network without authentication. An attacker can trigger a crash by sending specially crafted RTP packets containing excessive frame data, causing the application to become unavailable.

PJSIP versions prior to 2.17 contain a heap use-after-free vulnerability in the event subscription framework that can be triggered through presence unsubscription requests, allowing remote attackers without authentication to cause denial of service. The vulnerability resides in the evsub.c component and is exploitable over the network with no user interaction required. A patch is available in version 2.17 and later.

PJSIP versions 2.16 and below contain a heap buffer overflow in the H.264 video unpacketizer that fails to properly validate NAL unit size fields in malformed SRTP packets, allowing remote attackers to trigger memory corruption on systems receiving H.264 video streams. The vulnerability has a CVSS score of 5.3 and enables information disclosure through heap memory access. A patch is available for affected deployments.

PJSIP versions before 2.17 contain a use-after-free vulnerability in the H.264 packetizer that allows local attackers with user privileges to cause denial of service through malformed H.264 bitstreams lacking proper NAL unit markers. The flaw stems from inadequate pointer validation during packet processing, enabling out-of-bounds memory access that crashes the application. A patch is available in version 2.17 and later.

Buffer overflow in PJSIP multimedia library version 2.16 and earlier in PJNATH ICE implementation. Patch available. Affects VoIP/communication applications built on PJSIP.
