Synopsis
The remote Debian host is missing one or more security-related updates.Description
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.
Solution
Upgrade the pjproject packages.For Debian 9 stretch, these problems have been fixed in version 2.5.5~dfsg-6+deb9u5.
