Language:

Synopsis

The remote Red Hat host is missing one or more security updates.

Description

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.

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)
