========================================================================== Ubuntu Security Notice USN-1296-1 December 08, 2011
acpid vulnerabilities ==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 11.10 - Ubuntu 11.04 - Ubuntu 10.10 - Ubuntu 10.04 LTS
Summary:
Several security issues were fixed in acpid.
Software Description: - acpid: Advanced Configuration and Power Interface daemon
Details:
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)
Update instructions:
The problem can be corrected by updating your system to the following package versions:
Ubuntu 11.10: acpid 1:2.0.10-1ubuntu2.3
Ubuntu 11.04: acpid 1:2.0.7-1ubuntu2.4
Ubuntu 10.10: acpid 1.0.10-5ubuntu4.4
Ubuntu 10.04 LTS: acpid 1.0.10-5ubuntu2.5
In general, a standard system update will make all the necessary changes.
