[GLSA-200505-09] Gaim: Denial of Service and buffer overflow vulnerabilties

Vulnerability Assessment Summary
Gaim: Denial of Service and buffer overflow vulnerabilties

Detailed Explanation for this Vulnerability Assessment
The remote host is affected by the vulnerability described in GLSA-200505-09
(Gaim: Denial of Service and buffer overflow vulnerabilties)


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 (CVE-2005-1261). Siebe
Tolsma discovered that Gaim is also vulnerable to a remote Denial of
Service attack when receiving a specially crafted MSN message
(CVE-2005-1262).

Impact

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.

Workaround

There are no known workarounds at this time.
