XChat SOCKS 5 Remote Buffer Overrun Vulnerability
A remotely exploitable buffer overrun was reported in XChat. This issue exists in the SOCKS 5 proxy code. This stack-based buffer overrun could be exploited by a malicious proxy server if SOCKS 5 traversal has been enabled in the client. Successful exploitation will result in execution of arbitrary code as the client user. It should be noted that SOCKS 5 traversal is not enabled by default and this issue only poses a risk if the victim user deliberately connects to an attacker's SOCKS 5 proxy server. |
