Mandriva Linux Security Advisory : acpid (MDVSA-2012:137)
Medium Nessus Plugin ID 61983
SynopsisThe remote Mandriva Linux host is missing a security update.
DescriptionMultiple 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.
SolutionUpdate the affected acpid package.
