Does this matter?

High impact if exploited, but EPSS currently rates exploitation as unlikely (1.85%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.

Description

A stack-buffer overflow vulnerability exists in all versions of sngrep since v1.4.1. The flaw is due to inadequate bounds checking when copying 'Content-Length' and 'Warning' headers into fixed-size buffers in the sip_validate_packet and sip_parse_extra_headers functions within src/sip.c. This vulnerability allows remote attackers to execute arbitrary code or cause a denial of service (DoS) via crafted SIP messages.
