Update to 2.10.10 Security fix for CVE-2014-3694, CVE-2014-3695, CVE-2014-3696, CVE-2014-3698

Note that Tenable Network Security has extracted the preceding description block directly from the Fedora security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

The following issues were fixed in this update :

  + General :

  - Check the basic constraints extension when validating     SSL/TLS certificates. This fixes a security hole that     allowed a malicious man-in-the-middle to impersonate an     IM server or any other https endpoint. This affected     both the NSS and GnuTLS plugins (CVE-2014-3694,     boo#902495).

  - Allow and prefer TLS 1.2 and 1.1 when using the NSS     plugin for SSL (im#15909).

  + libpurple3 compatibility :

  - Encrypted account passwords are preserved until the new     one is set.

  - Fix loading Google Talk and Facebook XMPP accounts.

  + Groupwise: Fix potential remote crash parsing server     message that indicates that a large amount of memory     should be allocated (CVE-2014-3696, boo#902410).

  + IRC: Fix a possible leak of unencrypted data when using     /me command with OTR (im#15750).

  + MXit: Fix potential remote crash parsing a malformed     emoticon response (CVE-2014-3695, boo#902409).

  + XMPP :

  - Fix potential information leak where a malicious XMPP     server and possibly even a malicious remote user could     create a carefully crafted XMPP message that causes     libpurple to send an XMPP message containing arbitrary     memory (CVE-2014-3698, boo#902408).

  + Yahoo: Fix login when using the GnuTLS library for TLS     connections (im#16172, boo#874606).

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.
