Synopsis
========
Gaim contains several security issues that might allow an attacker to
execute arbitrary code or commands.
Background
==========
Gaim is a multi-protocol instant messaging client for Linux which
supports many instant messaging protocols.
Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 net-im/gaim < 0.81-r5 >= 0.81-r5
Description
===========
Gaim fails to do proper bounds checking when:
* Handling MSN messages (partially fixed with GLSA 200408-12).
* Handling rich text format messages.
* Resolving local hostname.
* Receiving long URLs.
* Handling groupware messages.
* Allocating memory for webpages with fake content-length header.
Furthermore Gaim fails to escape filenames when using drag and drop
installation of smiley themes.
Impact
======
These vulnerabilites could allow an attacker to crash Gaim or execute
arbitrary code or commands with the permissions of the user running
Gaim.
Workaround
==========
There is no known workaround at this time. All users are encouraged to
upgrade to the latest available version of Gaim.
Resolution
==========
All gaim users should upgrade to the latest version:
# emerge sync
# emerge -pv ">=net-im/gaim-0.81-r5"
# emerge ">=net-im/gaim-0.81-r5"
