APP: PSI Remote Integer Overflow DoS
This signature detects attempts to exploit a known vulnerability against PSI Jabber client version 0.12.1 and earlier. A successful attack can result in a denial-of-service condition.
Extended Description
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.
