Linux Distros Unpatched Vulnerability : CVE-2023-38703

critical Nessus Plugin ID 226029

Language:

Synopsis

The Linux/Unix host has one or more packages installed with a vulnerability that the vendor indicates will not be patched.

Description

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

- PJSIP is a free and open source multimedia communication library written in C with high level API in C, C++, Java, C#, and Python languages. SRTP is a higher level media transport which is stacked upon a lower level media transport such as UDP and ICE. Currently a higher level transport is not synchronized with its lower level transport that may introduce use-after-free issue. This vulnerability affects applications that have SRTP capability (`PJMEDIA_HAS_SRTP` is set) and use underlying media transport other than UDP.
This vulnerability's impact may range from unexpected application termination to control flow hijack/memory corruption. The patch is available as a commit in the master branch. (CVE-2023-38703)

Note that Nessus relies on the presence of the package as reported by the vendor.

Solution

There is no known solution at this time.
