CVE-2008-4933: Buffer Overflow
First published: Wed Nov 05 2008(Updated: )
Buffer overflow in the hfsplus_find_cat function in fs/hfsplus/catalog.c in the Linux kernel before 2.6.28-rc1 allows attackers to cause a denial of service (memory corruption or system crash) via an hfsplus filesystem image with an invalid catalog namelength field, related to the hfsplus_cat_build_key_uni function.
