Synopsis :

The remote Gentoo host is missing one or more security-related

Description :

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 (CAN-2005-0988), as well as improper
handling of filename restoration (CAN-2005-1228). The zgrep utility
improperly sanitizes arguments, which may come from an untrusted source

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.

# emerge --sync
# emerge --ask --oneshot --verbose '>=app-arch/gzip-1.3.5-r6'
