    Potential infinite loop when parsing WAV format file in PJSIP

    PJSIP is a free and open source multimedia communication library written in C. A denial-of-service vulnerability affects applications on a 32-bit systems that use PJSIP versions 2.12 and prior to play/read invalid WAV files. The vulnerability occurs when reading WAV file data chunks with length greater than 31-bit integers. The vulnerability does not affect 64-bit apps and should not affect apps that only plays trusted WAV files. A patch is available on the `master` branch of the `pjsip/project` GitHub repository. As a workaround, apps can reject a WAV file received from an unknown source or validate the file first.

    Kritisch · CVSS 9.8EPSS 7,03%Keine Korrektur veröffentlicht

    CVE-2022-26651

    An issue was discovered in Asterisk through 19.x and Certified Asterisk through 16.8-cert13. The func_odbc module provides possibly inadequate escaping functionality for backslash characters in SQL queries, resulting in user-provided data creating a broken SQL query or possibly a SQL injection. This is fixed in 16.25.2, 18.11.2, and 19.3.2, and 16.8-cert14.

    Use after free in PJSIP

    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 up to and including 2.11.1 when in a dialog set (or forking) scenario, a hash key shared by multiple UAC dialogs can potentially be prematurely freed when one of the dialogs is destroyed . The issue may cause a dialog set to be registered in the hash table multiple times (with different hash keys) leading to undefined behavior such as dialog list collision which eventually leading to endless loop. A patch is available in commit db3235953baa56d2fb0e276ca510fefca7516
