New! Vulnerability Priority Rating (VPR)

Tenable calculates a dynamic VPR for every vulnerability. VPR combines vulnerability information with threat intelligence and machine learning algorithms to predict which vulnerabilities are most likely to be exploited in attacks. Read more about what VPR is and how it's different from CVSS.

Synopsis

The remote openSUSE host is missing a security update.

Description

This update of glibc fixes two bugs and security issues :

CVE-2010-3847: Decoding of the $ORIGIN special value in various LD_ environment variables allowed local attackers to execute code in context of e.g. setuid root programs, elevating privileges. This issue does not affect SUSE as an assertion triggers before the respective code is executed. The bug was fixed nevertheless.

CVE-2010-3856: The LD_AUDIT environment was not pruned during setuid root execution and could load shared libraries from standard system library paths. This could be used by local attackers to inject code into setuid root programs and so elevated privileges.

Solution

Update the affected glibc packages.
