What the vulnerability does

01Description

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.
