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


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 (CAN-2005-0758).
Impact :

These vulnerabilities could allow 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.


All gzip users should upgrade to the latest stable version:
# emerge --sync # emerge --ask --oneshot --verbose '>=app-arch/gzip-1.3.5-r6'
