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 / Vulnerable / Unaffected ------------------------------------------------------------------- 1 net-im/pidgin < 2.5.1 >=3D 2.5.1
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:
# emerge --sync # emerge --ask --oneshot --verbose ">=3Dnet-im/pidgin-2.5.1"
