CVSS: 9.1EPSS: 0%CPEs: 19EXPL: 0CVE-2022-21723 – Out-of-bounds read in multipart parsing in PJSIP
https://notcve.org/view.php?id=CVE-2022-21723
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 versions 2.11.1 and prior, parsing an incoming SIP message that contains a malformed multipart can potentially cause out-of-bound read access. This issue affects all PJSIP users that accept SIP multipart. The patch is available as commit in the `master` branch. There are no known workarounds. • http://packetstormsecurity.com/files/166227/Asterisk-Project-Security-Advisory-AST-2022-006.html http://seclists.org/fulldisclosure/2022/Mar/2 https://github.com/pjsip/pjproject/commit/077b465c33f0aec05a49cd2ca456f9a1b112e896 https://github.com/pjsip/pjproject/security/advisories/GHSA-7fw8-54cv-r7pm 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-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 res_pjsip_session crash was discovered in Asterisk Open Source 13.x before 13.37.1, 16.x before 16.14.1, 17.x before 17.8.1, and 18.x before 18.0.1. and Certified Asterisk before 16.8-cert5. Upon receiving a new SIP Invite, Asterisk did not return the created dialog locked or referenced. This caused a gap between the creation of the dialog object, and its next use by the thread that created it. Depending on some off-nominal circumstances and timing, it was possible for another thread to free said dialog in this gap. Asterisk could then crash when the dialog object, or any of its dependent objects, were dereferenced or accessed next by the initial-creation thread. • http://downloads.asterisk.org/pub/security/AST-2020-001.html https://issues.asterisk.org/jira/browse/ASTERISK-29057 • CWE-404: Improper Resource Shutdown or Release •

https://notcve.org/view.php?id=CVE-2020-28242
An issue was discovered in Asterisk Open Source 13.x before 13.37.1, 16.x before 16.14.1, 17.x before 17.8.1, and 18.x before 18.0.1 and Certified Asterisk before 16.8-cert5. If Asterisk is challenged on an outbound INVITE and the nonce is changed in each response, Asterisk will continually send INVITEs in a loop. This causes Asterisk to consume more and more memory since the transaction will never terminate (even if the call is hung up), ultimately leading to a restart or shutdown of Asterisk. Outbound authentication must be configured on the endpoint for this to occur. Se detectó un problema en Asterisk Open Source versiones 13.x anteriores a 13.37.1, versiones 16.x anteriores a 16.14.1, versiones 17.x anteriores a 17.8.1 y versiones 18.x anteriores a 18.0.1 y Certified Asterisk versiones anteriores a 16.8-cert5. • http://downloads.asterisk.org/pub/security/AST-2020-002.html https://lists.debian.org/debian-lts-announce/2022/04/msg00001.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/QUS54QTQCYKR36EIULYD544GXDA644HB • CWE-674: Uncontrolled Recursion •

A memory exhaustion vulnerability exists in Asterisk Open Source 13.x before 13.15.1 and 14.x before 14.4.1 and Certified Asterisk 13.13 before 13.13-cert4, which can be triggered by sending specially crafted SCCP packets causing an infinite loop and leading to memory exhaustion (by message logging in that loop). Existe una vulnerabilidad de agotamiento de memoria en Asterisk Open Source, en versiones 13.x anteriores a la 13.15.1 y versiones 14.x anteriores a la 14.4.1, y en Certified Asterisk, en versiones 13.13 anteriores a la 13.13-cert4. Esto podría llevarse a cabo mediante el envío de paquetes SCCP especialmente manipulados que provocarían un bucle infinito y darían lugar a un agotamiento de memoria (mediante el registro de mensajes en ese bucle). • http://downloads.asterisk.org/pub/security/AST-2017-004.txt http://www.securityfocus.com/bid/98573 http://www.securitytracker.com/id/1038531 https://bugs.debian.org/863906 • CWE-835: Loop with Unreachable Exit Condition ('Infinite Loop') •
