Gaim is a full featured instant messaging client which handles a
variety of instant messaging protocols.
Stu Tomlinson discovered that Gaim is vulnerable to a remote stack
based buffer overflow when receiving messages in certain protocols,
like Jabber and SILC, with a very long URL (CAN-2005-1261). Siebe
Tolsma discovered that Gaim is also vulnerable to a remote Denial of
Service attack when receiving a specially crafted MSN message
<impact type="high">
A remote attacker could cause a buffer overflow by sending an
instant message with a very long URL, potentially leading to the
execution of malicious code. By sending a SLP message with an empty
body, a remote attacker could cause a Denial of Service or crash of the
Gaim client.
There are no known workarounds at this time.
All Gaim users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose &quot;&gt;=net-im/gaim-1.3.0&quot;</code>
