CVE-2013-6485 [MEDIUM] CVE-2013-6485 pidgin: Heap-based buffer overflow when parsing chunked HTTP responses
CVE-2013-6485 pidgin: Heap-based buffer overflow when parsing chunked HTTP responses
A Heap-based buffer overflow was found in the way pidgin processed chunked HTTP responses. 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 arbitary code with the permissions of the user running pidgin.
