Doc Text:
A flaw was found in SIPp. A local attacker can exploit a buffer overflow vulnerability by providing oversized input to command-line arguments, such as -3pcc, -i, or -log_file. This can lead to arbitrary code execution or cause the application to crash, resulting in a denial of service.

Description OSIDB Bzimport 2026-05-23 19:01:20 UTC 
SIPp 3.6 and earlier contains a local buffer overflow vulnerability in command-line argument handling that allows local attackers to crash the application or execute arbitrary code. Attackers can trigger the vulnerability by supplying oversized input to the -3pcc, -i, or -log_file parameters, causing strcpy to write beyond buffer boundaries in sipp.cpp.
