FreeBSD Security Advisory FreeBSD-SA-02:35 - FFS, the default FreeBSD filesystem has an overflow in the maximum permitted FFS file size which allows users to create files that are larger than FreeBSD's virtual memory system can handle. The integer overflows that result when such files are accessed can map filesystem metadata into the user file, permitting access to arbitrary filesystem blocks. The bug is encountered only on FFS filesystems with a block size of 16k or greater on the i386 architecture, or 32k or greater on the alpha architecture.
