The glibc packages contain the standard C libraries used by multiple programs on the system. These packages contain the standard C and the standard math libraries. Without these two libraries, a Linux system cannot function properly.
It was discovered that the glibc dynamic linker/loader did not perform sufficient safety checks when loading dynamic shared objects (DSOs) to provide callbacks for its auditing API during the execution of privileged programs. A local attacker could use this flaw to escalate their privileges via a carefully-chosen system DSO library containing unsafe constructors. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2010-3856 to this issue.
More information about these vulnerabilities can be found in the security advisory issued by RedHat Linux:

Recommended Actions for System Products:
Avaya strongly recommends that customers follow networking and security best practices by implementing firewalls, ACLs, physical security or other appropriate access restrictions. Though Avaya believes such restrictions should always be in place; risk to Avaya's product and the surrounding network from this potential vulnerability may be mitigated by ensuring these practices are implemented until such time as a product update is available or the recommended action is applied. Further restrictions as deemed necessary based on the customer's security policies may be required during this interim period.
When determining risk, Avaya takes into account many factors as outlined by Avaya's Security Vulnerability Classification Policy. The following table describes factors that mitigate the risk of specific vulnerabilities for the listed affected Avaya products:
||Avaya has rated this a Low for all products as it would require privileged account access to exploit.|
Avaya software-only products operate on general-purpose operating systems. Occasionally vulnerabilities may be discovered in the underlying operating system or applications that come with the operating system. These vulnerabilities often do not impact the software-only product directly but may threaten the integrity of the underlying platform.
In the case of this advisory Avaya software-only products are not affected by the vulnerability directly but the underlying Linux platform may be. Customers should determine on which Linux operating system the product was installed and then follow that vendor's guidance.
