Recommendation: Plan a near-term fix — a public PoC already exists.

Yasr 0.6.9-5 contains a buffer overflow vulnerability that allows local attackers to crash the application or execute arbitrary code by supplying an oversized argument to the -p parameter. Attackers can invoke yasr with a crafted payload containing junk data, shellcode, and a return address to overwrite the stack and trigger code execution.
