Package: squashfs-tools
Version: 1:2.2r2-2ubuntu2
Severity: critical
Tags: patch
Justification: causes the kernel to PANIC on an attempt to read from the
generated filesystem (unrelated package to break); and vital indexes are
lost so data in the generated filesystem cannot be retrieved (data loss)
Attached is a patch to correct a rounding error in the generation of the
fragment table indexes of generated squashfs filesystems. If the number
of fragments divides evenly into the size of each fragment table chunk
then the code believes that there are 0 bytes available in the buffer
rather then 8192 bytes.
This results in code being unable to obtain the final part of the
fragment index, making the files inaccessible and due to insufficient
sanity checking in the kernel code, the kernel PANIC.
I've also sent this patch upstream, who has verified that it is correct
and there is indeed a bug here. Note that although the patch is against
2.2r2, the difference is small enough that it will apply successfully to
3.0
