high Nessus Plugin ID 57743

Language:

Synopsis

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

Description

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.

Solution

Update the affected packages.
