CVE-2016-20047 identifies a local buffer overflow vulnerability in EKG Gadu version 1.9~pre+r2855-3+b1, affecting its username handling functionality. This high-severity flaw (CVSS 8.4) allows a local attacker to achieve arbitrary code execution with user privileges by providing an oversized username string that triggers a buffer overflow via the strlcpy function. The attack requires local access but no user interaction or prior privileges. Currently, there is no evidence of active exploitation, nor is public exploit code available in common databases like Metasploit or ExploitDB, and community discussion remains minimal.
