high Nessus Plugin ID 49204

Language:

Synopsis

The remote CentOS host is missing one or more security updates.

Description

Updated rpm packages that fix one security issue and one bug are now available for Red Hat Enterprise Linux 5.

The Red Hat Security Response Team has rated this update as having moderate security impact. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available from the CVE link in the References section.

The RPM Package Manager (RPM) is a command line driven package management system capable of installing, uninstalling, verifying, querying, and updating software packages.

It was discovered that RPM did not remove setuid and setgid bits set on binaries when upgrading packages. A local attacker able to create hard links to binaries could use this flaw to keep those binaries on the system, at a specific version level and with the setuid or setgid bit set, even if the package providing them was upgraded by a system administrator. This could have security implications if a package was upgraded because of a security flaw in a setuid or setgid program.
(CVE-2010-2059)

This update also fixes the following bug :

* A memory leak in the communication between RPM and the Security-Enhanced Linux (SELinux) subsystem, which could have caused extensive memory consumption. In reported cases, this issue was triggered by running rhn_check when errata were scheduled to be applied. (BZ#627630)

All users of rpm are advised to upgrade to these updated packages, which contain backported patches to correct these issues.

Solution

Update the affected rpm packages.
