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"
