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

SC v7.16 contains a stack-based buffer overflow vulnerability that allows local attackers to execute arbitrary code by supplying oversized input that exceeds buffer boundaries. Attackers can craft malicious input strings exceeding 1052 bytes to overwrite the instruction pointer and execute shellcode in the application context.
