CVE-2016-20037
xwpe 1.5.30a-2.1 and prior contains a stack-based buffer overflow vulnerability that allows local attackers to execute arbitrary code by supplying overly long input strings that exceed buffer boundaries.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.15%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
xwpe 1.5.30a-2.1 and prior contains a stack-based buffer overflow vulnerability that allows local attackers to execute arbitrary code by supplying overly long input strings that exceed buffer boundaries. Attackers can craft malicious command-line arguments with 262 bytes of junk data followed by shellcode to overwrite the instruction pointer and achieve code execution or denial of service.
