Mandriva Linux Security Advisory : acpid (MDVSA-2012:137)

This script is Copyright (C) 2012-2013 Tenable Network Security, Inc.

Synopsis :

The remote Mandriva Linux host is missing a security update.

Description :

Multiple vulnerabilities has been discovered and corrected in acpid :

Oliver-Tobias Ripka discovered that an ACPI script incorrectly handled
power button events. A local attacker could use this to execute
arbitrary code, and possibly escalate privileges (CVE-2011-2777).

Helmut Grohne and Michael Biebl discovered that ACPI scripts were
executed with a permissive file mode creation mask (umask). A local
attacker could read files and modify directories created by ACPI
scripts that did not set a strict umask (CVE-2011-4578).

The updated packages have been patched to correct these issues.

Solution :

Update the affected acpid package.

Risk factor :

Medium / CVSS Base Score : 4.6
CVSS Temporal Score : 4.0
Public Exploit Available : true
