[CRITICAL] Four vulnerabilities in Pidgin
The VRT is announcing the discovery and patching of 4 CVE vulnerabilities in Pidgin. These vulnerabilities were discovered by the VRT VULNDEV team and reported to the Pidgin team. The VRT also created TRUFFLE rules that have been protecting Sourcefire customers for these vulnerabilities since October 1st 2013, while the Pidgin team was working on patching them. TRUFFLE rules provide a way for the VRT to release cutting edge coverage without exposing threats to the public through a plaintext rule. We are releasing these rules publicly as part of our update today, since the Pidgin team is releasing Pidgin 2.10.8 that addresses these issues.

## Description An exploitable remote code execution vulnerability exists in Pidgin's implementation of the Mxit protocol in the libpurple library. An attacker who can control the contents of an Emoticon downloaded through the Mxit protocol can cause an allocation to return NULL which can later be used to write into the lowest page of memory. An attack requires the ability to spoof messages from the mxit.com domain to exploit this vulnerability.

CVE-2013-6489 pidgin: Heap-based buffer overflow in MXit emoticon parsing
A Heap-based buffer overflow was found in the way MXit protocol plugin of pidgin parsed emoticons. A malicious server could provide a specially crafted emoticon value, which could cause an integer overflow leading to a buffer overflow. This could cause pidgin to crash or possibly execute arbitrary code with the permissions of the user running pidgin.
