GLSA-200910-02 : Pidgin: Multiple vulnerabilities

This script is Copyright (C) 2009-2014 Tenable Network Security, Inc.


Synopsis :

The remote Gentoo host is missing one or more security-related
patches.

Description :

The remote host is affected by the vulnerability described in GLSA-200910-02
(Pidgin: Multiple vulnerabilities)

Multiple vulnerabilities were found in Pidgin:
Yuriy
Kaminskiy reported that the OSCAR protocol implementation in Pidgin
misinterprets the ICQWebMessage message type as the ICQSMS message
type, triggering an allocation of a large amount of memory
(CVE-2009-1889).
Federico Muttis of Core Security Technologies
reported that the msn_slplink_process_msg() function in
libpurple/protocols/msn/slplink.c in libpurple as used in Pidgin
doesn't properly process incoming SLP messages, triggering an overwrite
of an arbitrary memory location (CVE-2009-2694). NOTE: This issue
reportedly exists because of an incomplete fix for CVE-2009-1376 (GLSA
200905-07).
bugdave reported that protocols/jabber/auth.c in
libpurple as used in Pidgin does not follow the 'require TSL/SSL'
preference when connecting to older Jabber servers that do not follow
the XMPP specification, resulting in a connection to the server without
the expected encryption (CVE-2009-3026).

Impact :

A remote attacker could send specially crafted SLP (via MSN) or ICQ web
messages, possibly leading to execution of arbitrary code with the
privileges of the user running Pidgin, unauthorized information
disclosure, or a Denial of Service.

Workaround :

There is no known workaround at this time.

Solution :

All Pidgin users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose '>=net-im/pidgin-2.5.9-r1'

Risk factor :

Critical / CVSS Base Score : 10.0
(CVSS2#AV:N/AC:L/Au:N/C:C/I:C/A:C)
