Title: BitchX Remote cannot_join_channel() Buffer Overflow Vulnerability
Severity: HIGH
Description:
BitchX is a freely available, open source IRC client. It is available for Unix, Linux, and Microsoft operating systems.
A memory corruption vulnerability has been discovered in BitchX 1.0c19. This issue occurs when calling the cannot_join_channel() function. If a channel of excessive length is supplied a buffer overflow could occur which may result in predefined strings being written over sensitive stack memory.
As a result, it may be possible for a malicious IRC server to crash a vulnerable client. Although unconfirmed this vulnerability could potentially be leveraged to execute arbitrary commands within a target client.
This vulnerability has been reported to affect BitchX 1.0c19. Other versions may also be affected.
This issue was originally described in BID 7086 "Multiple BitchX Remote Client-Side Buffer Overflow Vulnerabilities" and is now being assigned a separate BID.
