[GLSA-200505-05] gzip: Multiple vulnerabilities

Vulnerability Assessment Summary
gzip: Multiple vulnerabilities

Detailed Explanation for this Vulnerability Assessment
The remote host is affected by the vulnerability described in GLSA-200505-05
(gzip: Multiple vulnerabilities)

The gzip and gunzip programs are vulnerable to a race condition
when setting file permissions (CVE-2005-0988), as well as improper
handling of filename restoration (CVE-2005-1228). The zgrep utility
improperly sanitizes arguments, which may come from an untrusted source
(CVE-2005-0758).

Impact

These vulnerabilities could permit arbitrary command execution,
changing the permissions of arbitrary files, and installation of files
to an aribitrary location in the filesystem.

Workaround

There is no known workaround at this time.
