GLSA-200404-04 : Multiple vulnerabilities in sysstat
Medium Nessus Plugin ID 14469
SynopsisThe remote Gentoo host is missing one or more security-related patches.
DescriptionThe remote host is affected by the vulnerability described in GLSA-200404-04 (Multiple vulnerabilities in sysstat)
There are two vulnerabilities in the way sysstat handles symlinks:
The isag utility, which displays sysstat data in a graphical format, creates a temporary file in an insecure manner.
Two scripts in the sysstat package, post and trigger, create temporary files in an insecure manner.
Both vulnerabilities may allow an attacker to overwrite arbitrary files under the permissions of the user executing any of the affected utilities.
A workaround is not currently known for this issue. All users are advised to upgrade to the latest version of the affected package.
SolutionSystat users should upgrade to version 4.2 or later:
# emerge sync # emerge -pv '>=app-admin/sysstat-5.0.2' # emerge '>=app-admin/sysstat-5.0.2'
