Multiple vulnerabilities were found in Pidgin:
|
|
</p>
|
|
<ul>
|
|
<li>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).</li>
|
|
<li>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).</li>
|
|
<li>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).</li>
|
|
</ul>
|
|
</description>
|
|
<impact type="high">
|
|
<p>
|
|
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.
|
|
</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-2.5.9-r1"</code>
|
|
</resolution>
