Category:FreeBSD Local Security Checks
Title:FreeBSD Security Advisory (FreeBSD-SA-05:11.gzip.asc)
Summary:The remote host is missing an update to the system; as announced in the referenced advisory FreeBSD-SA-05:11.gzip.asc
Description:Summary:
The remote host is missing an update to the system
as announced in the referenced advisory FreeBSD-SA-05:11.gzip.asc

Vulnerability Insight:
gzip is a file compression utility.

Two problems related to extraction of files exist in gzip:

The first problem is that gzip does not properly sanitize filenames
containing / when uncompressing files using the -N command line
option.

The second problem is that gzip does not set permissions on newly
extracted files until after the file has been created and the file
descriptor has been closed.

Solution:
Upgrade your system to the appropriate stable release
or security branch dated after the correction date.
