Description:
Leon Juranic has reported a vulnerability in BNC IRC proxy, which can be exploited by malicious people to cause a DoS (Denial of Service) and potentially compromise a vulnerable system.
The vulnerability is caused due to some boundary errors in the "getnickuserhost()" function in "cmds.c" when processing IRC server responses. This can be exploited by a malicious server to cause a buffer overflow.
Successful exploitation crashes the process but may potentially also allow execution of arbitrary code.
The vulnerability has been reported in version 2.8.9. Other versions may also be affected.
