Description Marcel Holtmann 2006-11-22 16:42:04 EST

From MOKB-07-11-2006:

http://projects.info-pull.com/mokb/MOKB-07-11-2006.html

Linux 2.6.x zlib_inflate function can be abused by filesystems that depend on
zlib compression, such as cramfs. A failure to handle crafted data, result of a
read operation in a corrupted filesystem stream, may lead to memory corruption.
This particular vulnerability requires a filesystem (proof of concept for cramfs
provided) to fail validation (ex. no integrity checking) of the binary stream in
order to reach execution of zlib_inflate().

As long as I've got the other ones...
