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.
