1. Summary:

An update for pidgin is now available for Red Hat Enterprise Linux 7.

Red Hat Product Security has rated this update as having a security impact
of Moderate. A Common Vulnerability Scoring System (CVSS) base score, which
gives a detailed severity rating, is available for each vulnerability from
the CVE link(s) in the References section.

3. Description:

Pidgin is an instant messaging program which can log in to multiple
accounts on multiple instant messaging networks simultaneously.

The following packages have been upgraded to a later upstream version:
pidgin (2.10.11). (BZ#1369526)

Security Fix(es):

* A denial of service flaw was found in the way Pidgin's Mxit plug-in
handled emoticons. A malicious remote server or a man-in-the-middle
attacker could potentially use this flaw to crash Pidgin by sending a
specially crafted emoticon. (CVE-2014-3695)

* A denial of service flaw was found in the way Pidgin parsed Groupwise
server messages. A malicious remote server or a man-in-the-middle attacker
could potentially use this flaw to cause Pidgin to consume an excessive
amount of memory, possibly leading to a crash, by sending a specially
crafted message. (CVE-2014-3696)

* An information disclosure flaw was discovered in the way Pidgin parsed
XMPP messages. A malicious remote server or a man-in-the-middle attacker
could potentially use this flaw to disclose a portion of memory belonging
to the Pidgin process by sending a specially crafted XMPP message.
(CVE-2014-3698)

* An out-of-bounds write flaw was found in the way Pidgin processed XML
content. A malicious remote server could potentially use this flaw to crash
Pidgin or execute arbitrary code in the context of the pidgin process.
(CVE-2017-2640)

* It was found that Pidgin's SSL/TLS plug-ins had a flaw in the certificate
validation functionality. An attacker could use this flaw to create a fake
certificate, that Pidgin would trust, which could be used to conduct
man-in-the-middle attacks against Pidgin. (CVE-2014-3694)

Red Hat would like to thank the Pidgin project for reporting these issues.
Upstream acknowledges Yves Younan (Cisco Talos) and Richard Johnson (Cisco
Talos) as the original reporters of CVE-2014-3695 and CVE-2014-3696; Thijs
Alkemade and Paul Aurich as the original reporters of CVE-2014-3698; and
Jacob Appelbaum and Moxie Marlinspike as the original reporters of
CVE-2014-3694.
