TITLE:
Pidgin MSN Custom Smileys File Disclosure Vulnerability

SECUNIA ADVISORY ID:
SA37953

VERIFY ADVISORY:
http://secunia.com/advisories/37953/

DESCRIPTION:
Fabian Yamaguchi has discovered a vulnerability in Pidgin, which can
be exploited by malicious people to disclose sensitive information.

The vulnerability is caused due to an error in the implementation of
the custom smileys feature for MSN. This can be exploited to disclose
the content of arbitrary files via an MSN emoticon request containing
directory traversal sequences.

Successful exploitation may require that at least one custom smiley
is defined.

The vulnerability is confirmed in version 2.6.4. Other versions may
also be affected.

SOLUTION:
Delete the "custom_smiley" directory from the ".purple" settings
directory.

PROVIDED AND/OR DISCOVERED BY:
Fabian 'fabs' Yamaguchi
