FreeBSD : FreeBSD -- errors handling corrupt compress file in compress(1) and gzip(1) (fee94342-4638-11e1-9f47-00e0815b8da8)

High Nessus Plugin ID 57743


The remote FreeBSD host is missing one or more security-related updates.


The code used to decompress a file created by compress(1) does not do sufficient boundary checks on compressed code words, allowing reference beyond the decompression table, which may result in a stack overflow or an infinite loop when the decompressor encounters a corrupted file.


Update the affected packages.
