Synopsis ========
Multiple vulnerabilities in the way sysstat handles symlinks may allow an attacker to execute arbitrary code or overwrite arbitrary files
Background ==========
sysstat is a package containing a number of performance monitoring utilities for Linux, including sar, mpstat, iostat and sa tools
Affected packages =================
------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- app-admin/sysstat < 5.0.2 >= 5.0.2
Description ===========
There are two vulnerabilities in the way sysstat handles symlinks:
1. The isag utility, which displays sysstat data in a graphical format, creates a temporary file in an insecure manner.
2. Two scripts in the sysstat package, post and trigger, create temporary files in an insecure manner.
Impact ======
Both vulnerabilities may allow an attacker to overwrite arbitrary files under the permissions of the user executing any of the affected utilities.
Workaround ==========
A workaround is not currently known for this issue. All users are advised to upgrade to the latest version of the affected package.
Resolution ==========
Systat 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"
