Description:
LMH has reported a vulnerability in Fedora Core, which can be exploited by malicious, local users to cause a DoS (Denial of Service).
The vulnerability is caused due to an error within the "zlib_inflate()" function when processing certain data streams. This can be exploited to corrupt memory by e.g. mounting a specially crafted cramfs image and performing a read operation on the mounted file system.
The vulnerability is reported in Fedora Core 6. Other versions may also be affected.
Solution:
Allow only trusted users to mount cramfs images.
