FreeBSD : LZO -- potential buffer overrun when processing malicious input data (d1f5e12a-fd5a-11e3-a108-080027ef73ec)

high Nessus Plugin ID 76269

Synopsis

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

Description

Markus Franz Xaver Johannes Oberhumer reports, in the package's NEWS file :

Fixed a potential integer overflow condition in the 'safe' decompressor variants which could result in a possible buffer overrun when processing maliciously crafted compressed input data.

As this issue only affects 32-bit systems and also can only happen if you use uncommonly huge buffer sizes where you have to decompress more than 16 MiB (2^24 bytes) compressed bytes within a single function call, the practical implications are limited.

Solution

Update the affected packages.
