Critical: tog-pegasus security updateThe tog-pegasus packages provide OpenPegasus Web-Based EnterpriseManagement (WBEM) services. WBEM is a platform and resource independentDMTF standard that defines a common information model, and communicationprotocol for monitoring and controlling resources.During a security audit, a stack buffer overflow flaw was found in the PAMauthentication code in the OpenPegasus CIM management server. Anunauthenticated remote user could trigger this flaw and potentially executearbitrary code with root privileges. (CVE-2008-0003)Note that the tog-pegasus packages are not installed by default on Red HatEnterprise Linux. The Red Hat Security Response Team believes that it wouldbe hard to remotely exploit this issue to execute arbitrary code, due tothe default SELinux targeted policy on Red Hat Enterprise Linux 4 and 5,and the SELinux memory protection tests enabled by default on Red HatEnterprise Linux 5.Users of tog-pegasus should upgrade to these updated packages, whichcontain a backported patch to resolve this issue. After installing theupdated packages the tog-pegasus service should be restarted.
