CVSS: 7.5EPSS: 0%CPEs: 3EXPL: 0CVE-2021-43804 – Out-of-bounds read when parsing RTCP BYE message in PJSIP
https://notcve.org/view.php?id=CVE-2021-43804
PJSIP is a free and open source multimedia communication library written in C language implementing standard based protocols such as SIP, SDP, RTP, STUN, TURN, and ICE. In affected versions if the incoming RTCP BYE message contains a reason's length, this declared length is not checked against the actual received packet size, potentially resulting in an out-of-bound read access. This issue affects all users that use PJMEDIA and RTCP. A malicious actor can send a RTCP BYE message with an invalid reason length. Users are advised to upgrade as soon as possible. • https://github.com/pjsip/pjproject/commit/8b621f192cae14456ee0b0ade52ce6c6f258af1e https://github.com/pjsip/pjproject/security/advisories/GHSA-3qx3-cg72-wrh9 https://lists.debian.org/debian-lts-announce/2022/03/msg00035.html https://lists.debian.org/debian-lts-announce/2022/11/msg00021.html https://lists.debian.org/debian-lts-announce/2023/08/msg00038.html https://security.gentoo.org/glsa/202210-37 https://www.debian.org/security/2022/dsa-5285 • CWE-125: Out-of-bounds Read •
CVSS: 9.8EPSS: 2%CPEs: 20EXPL: 0CVE-2021-37706 – Potential integer underflow upon receiving STUN message in PJSIP
https://notcve.org/view.php?id=CVE-2021-37706
PJSIP is a free and open source multimedia communication library written in C language implementing standard based protocols such as SIP, SDP, RTP, STUN, TURN, and ICE. In affected versions if the incoming STUN message contains an ERROR-CODE attribute, the header length is not checked before performing a subtraction operation, potentially resulting in an integer underflow scenario. This issue affects all users that use STUN. A malicious actor located within the victim’s network may forge and send a specially crafted UDP (STUN) message that could remotely execute arbitrary code on the victim’s machine. Users are advised to upgrade as soon as possible. • http://packetstormsecurity.com/files/166225/Asterisk-Project-Security-Advisory-AST-2022-004.html http://seclists.org/fulldisclosure/2022/Mar/0 https://github.com/pjsip/pjproject/commit/15663e3f37091069b8c98a7fce680dc04bc8e865 https://github.com/pjsip/pjproject/security/advisories/GHSA-2qpg-f6wf-w984 https://lists.debian.org/debian-lts-announce/2022/03/msg00035.html https://lists.debian.org/debian-lts-announce/2022/11/msg00021.html https://lists.debian.org/debian-lts-announce/2023/08/msg00038.html https:/ • CWE-191: Integer Underflow (Wrap or Wraparound) •

A use-after-free exists in drivers/tee/tee_shm.c in the TEE subsystem in the Linux kernel through 5.15.11. This occurs because of a race condition in tee_shm_get_from_id during an attempt to free a shared memory object.
