New! Vulnerability Priority Rating (VPR)
Tenable calculates a dynamic VPR for every vulnerability. VPR combines vulnerability information with threat intelligence and machine learning algorithms to predict which vulnerabilities are most likely to be exploited in attacks. Read more about what VPR is and how it's different from CVSS.

SynopsisThe remote Gentoo host is missing one or more security-related patches.
DescriptionThe 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).
These vulnerabilities could allow arbitrary command execution, changing the permissions of arbitrary files, and installation of files to an aribitrary location in the filesystem.
There is no known workaround at this time.
SolutionAll gzip users should upgrade to the latest stable version:
# emerge --sync # emerge --ask --oneshot --verbose '>=app-arch/gzip-1.3.5-r6'
