3. Description:

Samba is a suite of programs used by machines to share files, printers, and
other information.

A heap-based buffer overflow flaw was found in the way Samba clients handle
over-sized packets. If a client connected to a malicious Samba server, it
was possible to execute arbitrary code as the Samba client user. It was
also possible for a remote user to send a specially crafted print request
to a Samba server that could result in the server executing the vulnerable
client code, resulting in arbitrary code execution with the permissions of
the Samba server. (CVE-2008-1105)

Red Hat would like to thank Alin Rad Pop of Secunia Research for
responsibly disclosing this issue.

Users of Samba are advised to upgrade to these updated packages, which
contain a backported patch to resolve this issue.
