RHEL 5 : acpid (RHSA-2009:1642)

high Nessus Plugin ID 43047

Synopsis

The remote Red Hat host is missing a security update for acpid.

Description

The remote Redhat Enterprise Linux 5 host has a package installed that is affected by a vulnerability as referenced in the RHSA-2009:1642 advisory.

acpid is a daemon that dispatches ACPI (Advanced Configuration and Power Interface) events to user-space programs.

It was discovered that acpid could create its log file (/var/log/acpid) with random permissions on some systems. A local attacker could use this flaw to escalate their privileges if the log file was created as world-writable and with the setuid or setgid bit set. (CVE-2009-4033)

Please note that this flaw was due to a Red Hat-specific patch (acpid-1.0.4-fd.patch) included in the Red Hat Enterprise Linux 5 acpid package.

Users are advised to upgrade to this updated package, which contains a backported patch to correct this issue.

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the RHEL acpid package based on the guidance in RHSA-2009:1642.
