Description: 
 Double free vulnerability in squashfs module in the Linux kernel
 2.6.x, as used in Fedora Core 5 and possibly other distributions,
 allows local users to cause a denial of service by mounting a crafted
 squashfs filesystem.
Ubuntu-Description: 
 Certain corrupted squashfs file system images caused a memory
 allocation to be freed twice. By mounting a specially crafted
 squashfs file system, a local attacker could exploit this to crash
 the kernel.
Notes: 
 Ubuntu kernels have squashfs patch; not sure about Debian's.
 dannf> Debian's do not, but we do have a kernel-patch-squashfs package
 dannf> Marking upstream N/A, because this isn't an upstream feature
 dannf> Affects squashfs (1:3.1r2-6) which is currently in etch. I've
        Verified that the patch in RH bugzilla applies and fixes the bug.
 dannf> kernel-patch-squashfs applied to a 2.4 kernel does not exhibit
        this problem. I tested by hexediting the reproducer fs to advertise
        v2 since v3 is not supported in sarge, which may have just masked
        the problem.
 dannf> Released in squashfs (1:3.1r2-6.1) which is in etch
