Gentoo Linux Security Advisory
Title: Pidgin: Multiple vulnerabilities (GLSA 200901-13)
Severity: normal
Exploitable: remote
Date: January 20, 2009
Bug(s): #230045, #234135
ID: 200901-13
Synopsis
Multiple vulnerabilities have been discovered in Pidgin, allowing for
remote arbitrary code execution, Denial of Service and service spoofing.
Background
Pidgin (formerly Gaim) is an instant messaging client for a variety of
instant messaging protocols. It is based on the libpurple instant
messaging library.
Affected Packages
Package: net-im/pidgin
Vulnerable: < 2.5.1
Unaffected: >= 2.5.1
Architectures: All supported architectures
Description
Multiple vulnerabilities have been discovered in Pidgin and the
libpurple library:
-
A participant to the TippingPoint ZDI reported multiple integer
overflows in the msn_slplink_process_msg() function in the MSN protocol
implementation (CVE-2008-2927).
-
Juan Pablo Lopez Yacubian is credited for reporting a use-after-free
flaw in msn_slplink_process_msg() in the MSN protocol implementation
(CVE-2008-2955).
-
The included UPnP server does not limit the size of data to be
downloaded for UPnP service discovery, according to a report by Andrew
Hunt and Christian Grothoff (CVE-2008-2957).
-
Josh Triplett discovered that the NSS plugin for libpurple does not
properly verify SSL certificates (CVE-2008-3532).
Impact
A remote attacker could send specially crafted messages or files using
the MSN protocol which could result in the execution of arbitrary code
or crash Pidgin. NOTE: Successful exploitation might require the
victim's interaction. Furthermore, an attacker could conduct
man-in-the-middle attacks to obtain sensitive information using bad
certificates and cause memory and disk resources to exhaust.
Workaround
There is no known workaround at this time.
Resolution
All Pidgin users should upgrade to the latest version:
Code: | # emerge --sync
# emerge --ask --oneshot --verbose ">=net-im/pidgin-2.5.1" |
