CVE-2024-3119

Summary

CVE-2024-3119 is a buffer overflow vulnerability affecting all versions of sngrep since v0.4.2. The issue arises from the improper handling of 'Call-ID' and 'X-Call-ID' SIP headers in the sip.c file. The functions sip_get_callid and sip_get_xcallid use the strncpy function to copy header contents into fixed-size buffers without checking the data length, leading to a buffer overflow. This vulnerability enables remote attackers to execute arbitrary code or cause a denial of service through specifically crafted SIP messages.
