Xchat : Security Vulnerabilities, CVEs, (Code Execution)

Heap-based buffer overflow in Xchat-WDK before 1499-4 (2012-01-18) xchat 2.8.6 on Maemo architecture could allow remote attackers to cause a denial of service (xchat client crash) or execute arbitrary code via a UTF-8 line from server containing characters outside of the Basic Multilingual Plane (BMP).

Format string vulnerability in XChat 1.2.x allows remote attackers to execute arbitrary code via a malformed nickname.

Stack-based buffer overflow in the Socks-5 proxy code for XChat 1.8.0 to 2.0.8, with socks5 traversal enabled, allows remote attackers to execute arbitrary code.

Untrusted search path vulnerability in the Python module in xchat allows local users to execute arbitrary code via a Trojan horse Python file in the current working directory, related to a vulnerability in the PySys_SetArgv function (CVE-2008-5983).

Heap-based buffer overflow in XChat 2.8.9 and earlier allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via a long response string.
