Pidgin (formerly Gaim) is an instant messaging client for a variety of
|
|
instant messaging protocols. It is based on the libpurple instant
|
|
messaging library.

Multiple vulnerabilities have been discovered in Pidgin and the
|
|
libpurple library:
|
|
</p>
|
|
<ul><li>
|
|
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).
|
|
</li>
|
|
<li>
|
|
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).
|
|
</li>
|
|
<li>
|
|
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).
|
|
</li>
|
|
<li>
|
|
Josh Triplett discovered that the NSS plugin for libpurple does not
|
|
properly verify SSL certificates (CVE-2008-3532).
|
|
</li>
|
|
</ul>

<impact type="normal">
|
|
<p>
|
|
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.
|
|
</p>
|
|
</impact>
|
|
<workaround>
|
|
<p>
|
|
There is no known workaround at this time.
|
|
</p>
|
|
</workaround>
|
|
<resolution>
|
|
<p>
|
|
All Pidgin users should upgrade to the latest version:
|
|
</p>
|
|
<code>
|
|
# emerge --sync
|
|
# emerge --ask --oneshot --verbose ">=net-im/pidgin-2.5.1"</code>
|
