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).

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.
