Name of the Vulnerable Software and Affected Versions:

sngrep versions 0.4.2 and later

Description:

A buffer overflow vulnerability exists due to improper handling of 'Call-ID' and 'X-Call-ID' SIP headers. The functions `sip get callid` and `sip get xcallid` in sip.c use the `strncpy` function to copy header contents into fixed-size buffers without checking the data length. This flaw allows remote attackers to execute arbitrary code or cause a denial of service (DoS) through specially crafted SIP messages.

Recommendations:

As a temporary workaround, consider disabling the `sip get callid` and `sip get xcallid` functions until a patch is available.

Restrict access to the vulnerable `sip.c` module to minimize the risk of exploitation.

Avoid using the `Call-ID` and `X-Call-ID` SIP headers in affected API endpoints until the issue is resolved.

At the moment, there is no information about a newer version that contains a fix for this vulnerability.
