Gentoo Linux Security Advisory

Title: Multiple vulnerabilities in sysstat (GLSA 200404-04)
Severity: normal
Exploitable: local
Date: April 06, 2004
Bug(s): #45159
ID: 200404-04

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: app-admin/sysstat
Vulnerable: < 5.0.2
Unaffected: >= 5.0.2
Architectures: x86 ppc sparc amd64


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:
Code:
# emerge sync
# emerge -pv ">=app-admin/sysstat-5.0.2"
# emerge ">=app-admin/sysstat-5.0.2"
