[GLSA]

Gentoo Linux Security Advisory

Title: Gaim: Multiple vulnerabilities (GLSA 200410-23)
Severity: high
Exploitable: remote
Date: October 24, 2004
Bug(s): #68271
ID: 200410-23

Synopsis


Multiple vulnerabilities have been found in Gaim which could allow a remote
attacker to crash the application, or possibly execute arbitrary code.


Background


Gaim is a full featured instant messaging client which handls a variety of
instant messaging protocols.


Affected Packages

Package: net-im/gaim
Vulnerable: < 1.0.2
Unaffected: >= 1.0.2
Architectures: All supported architectures


Description


A possible buffer overflow exists in the code processing MSN SLP messages
(CAN-2004-0891). memcpy() was used without validating the size of the
buffer, and an incorrect buffer was used as destination under certain
circumstances. Additionally, memory allocation problems were found in the
processing of MSN SLP messages and the receiving of files. These issues
could lead Gaim to try to allocate more memory than available, resulting in
the crash of the application.


Impact


A remote attacker could crash Gaim and possibly execute arbitrary code by
exploiting the buffer overflow.


Workaround


There is no known workaround at this time.


Resolution


All Gaim users should upgrade to the latest version:
