CVE-2008-6393 is a vulnerability of currently unknown severity. PSI Jabber client before 0.12.1 allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via a file transfer request with a negative value in a SOCKS5 option, which bypasses a signed integer check and triggers an integer overflow and a heap-based buffer overflow.. EPSS estimates a 18.20% chance of exploitation in the next 30 days.
