CVSS: 7.8EPSS: 0%CPEs: 2EXPL: 0CVE-2021-41141 – Missing release of locks in PJSIP
https://notcve.org/view.php?id=CVE-2021-41141
PJSIP is a free and open source multimedia communication library written in the C language implementing standard based protocols such as SIP, SDP, RTP, STUN, TURN, and ICE. In various parts of PJSIP, when error/failure occurs, it is found that the function returns without releasing the currently held locks. This could result in a system deadlock, which cause a denial of service for the users. No release has yet been made which contains the linked fix commit. All versions up to an including 2.11.1 are affected. • https://github.com/pjsip/pjproject/commit/1aa2c0e0fb60a1b0bf793e0d834073ffe50fb196 https://github.com/pjsip/pjproject/security/advisories/GHSA-8fmx-hqw7-6gmc https://lists.debian.org/debian-lts-announce/2022/03/msg00035.html https://security.gentoo.org/glsa/202210-37 • CWE-667: Improper Locking •
CVSS: 9.1EPSS: 0%CPEs: 4EXPL: 1CVE-2021-43845 – Prevent out-of-bounds read in PJSIP
https://notcve.org/view.php?id=CVE-2021-43845
PJSIP is a free and open source multimedia communication library. In version 2.11.1 and prior, if incoming RTCP XR message contain block, the data field is not checked against the received packet size, potentially resulting in an out-of-bound read access. This affects all users that use PJMEDIA and RTCP XR. A malicious actor can send a RTCP XR message with an invalid packet size. PJSIP es una biblioteca de comunicación multimedia gratuita y de código abierto. • https://github.com/pjsip/pjproject/commit/f74c1fc22b760d2a24369aa72c74c4a9ab985859 https://github.com/pjsip/pjproject/pull/2924 https://github.com/pjsip/pjproject/security/advisories/GHSA-r374-qrwv-86hh 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: 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) •

https://notcve.org/view.php?id=CVE-2021-32686
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 PJSIP before version 2.11.1, there are a couple of issues found in the SSL socket. First, a race condition between callback and destroy, due to the accepted socket having no group lock. Second, the SSL socket parent/listener may get destroyed during handshake. Both issues were reported to happen intermittently in heavy load TLS connections. • https://github.com/pjsip/pjproject/commit/d5f95aa066f878b0aef6a64e60b61e8626e664cd https://github.com/pjsip/pjproject/pull/2716 https://github.com/pjsip/pjproject/releases/tag/2.11.1 https://github.com/pjsip/pjproject/security/advisories/GHSA-cv8x-p47p-99wr https://lists.debian.org/debian-lts-announce/2022/03/msg00035.html https://security.gentoo.org/glsa/202210-37 https://www.debian.org/security/2021/dsa-4999 • CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') •
