[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. It is available for download here: http://www.pidgin.im/ Here is a summary of the vulnerabilities and the associated rules, with links to blog posts desc

## Sourcefire Vulnerability Report VRT-2013-1001 (CVE-2013-6487): Buffer overflow in Gadu-Gadu HTTP parsing
## Description An exploitable remote code execution vulnerability exists in Pidgin's implementation of the Gadu Gadu protocol in the libpurple library. An attacker who can control the Content-Length of a HTTP request can cause an undersized allocation which can later be used to overflow into the heap. An attack requires the ability to spoof messages from the gadu-gadu.pl domain to exploit this vulnerability.
## Tested Versions Pidgin 2.10.7
## Coverage Prior coverage through an http_inspect alert GID 120, SID 8 as well as SID 2580.

CVE-2013-6487 pidgin: Heap-based buffer overflow in Gadu-Gadu protocol plugin
A Heap-based buffer overflow was found in the way Gadu-Gadu protocol plugin of pidgin. A malicious server or man-in-the-middle could send a large value for Content-Length and cause an integer overflow which could lead to a buffer overflow. This could cause pidgin to crash or possibly execute arbitrary code with the permissions of the user running pidgin.
