The remote Debian 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the dla-3036 advisory.
PJSIP is a free and open source multimedia communication library written in the C language. Versions 2.12 and prior contain a denial-of-service vulnerability that affects PJSIP users that consume PJSIP’s XML parsing in their apps. Users are advised to update. There are no known workarounds. (CVE-2022-24763)
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.
(CVE-2022-24792)
PJSIP is a free and open source multimedia communication library written in C. A buffer overflow vulnerability in versions 2.12 and prior affects applications that uses PJSIP DNS resolution. It doesn’t affect PJSIP users who utilize an external resolver. A patch is available in the master
branch of the pjsip/pjproject
GitHub repository. A workaround is to disable DNS resolution in PJSIP config (by setting nameserver_count
to zero) or use an external resolver instead. (CVE-2022-24793)
Note that Nessus has not tested for these issues but has instead relied only on the application’s self-reported version number.
