Debian DSA 306-1: IrcII-Pana remote buffer overflow

by Nikola Strahija on May 20th, 2003 It has been reported that BitchX contains integer and buffer overflow vulnerabilities, that could allow a malicious IRC server to craft special reply strings, triggering the client into a denial-of-service status and may also lead to arbitrary code execution.

Debian Security Advisory DSA 306-1 [email protected] Martin Schulze
May 19th, 2003
- --------------------------------------------------------------------------

Package : ircii-pana
Vulnerability : buffer overflows, integer overflow
Problem-Type : remote
Debian-specific: no

Timo Sirainen discovered several problems in BitchX, a popular client
for Internet Relay Chat (IRC). A malicious server could craft special
reply strings, triggering the client to write beyond buffer boundaries
or allocate a negative amount of memory. This could lead to a denial
of service if the client only crashes, but may also lead to executing
of arbitrary code under the user id of the chatting user.

For the stable distribution (woody) these problems have been fixed in
version 1.0-0c19-1.1.

For the old stable distribution (potato) these problems have been
fixed in version 1.0-0c16-2.1.

For the unstable distribution (sid) these problems have been fixed in
version 1.0-0c19-8.

We recommend that you upgrade your BitchX package.
