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.
