A vulnerability was found in Pidgin up to 2.10.9 (Messaging Software). It has been classified as problematic. This affects an unknown functionality in the library libpurple. The manipulation as part of a Emoticon leads to a memory corruption vulnerability. CWE is classifying the issue as CWE-119. The product performs operations on a memory buffer, but it can read from or write to a memory location that is outside of the intended boundary of the buffer. This is going to have an impact on availability. The summary by CVE is:

markup.c in the MXit protocol plugin in libpurple in Pidgin before 2.10.10 allows remote servers to cause a denial of service (application crash) via a large length value in an emoticon response.

The weakness was published 10/22/2014 by Yves Younan and Richard Johnson with Cisco as confirmed advisory (Website). It is possible to read the advisory at pidgin.im. This vulnerability is uniquely identified as CVE-2014-3695 since 05/14/2014. It is possible to initiate the attack remotely. No form of authentication is needed for exploitation. Technical details of the vulnerability are known, but there is no available exploit. The advisory points out:

A malicious server or man-in-the-middle could trigger a crash in libpurple by sending an emoticon with an overly large length value.

The vulnerability scanner Nessus provides a plugin with the ID 80022 (SuSE 11.3 Security Update : pidgin (SAT Patch Number 10078)), which helps to determine the existence of the flaw in a target environment. It is assigned to the family SuSE Local Security Checks. The commercial vulnerability scanner Qualys is able to test this issue with plugin 236432 (Red Hat Update for pidgin (RHSA-2017:1854)).

Upgrading to version 2.10.10 eliminates this vulnerability. The upgrade is hosted for download at hg.pidgin.im. A possible mitigation has been published immediately after the disclosure of the vulnerability. The advisory contains the following remark:

Verify that the length value is valid before attempting to read data from the buffer.
