Scientific Linux Security Update : kernel on SL5.x i386/x86_64 (20130122)
medium Nessus Plugin ID 63677
Language:
Synopsis
The remote Scientific Linux host is missing one or more security updates.Description
This update fixes the following security issues :- It was found that the Xen hypervisor implementation did not perform range checking on the guest provided values in multiple hypercalls. A privileged guest user could use this flaw to trigger long loops, leading to a denial of service (Xen hypervisor hang). (CVE-2012-5515, Moderate)
- It was found that when running a 32-bit binary that uses a large number of shared libraries, one of the libraries would always be loaded at a predictable address in memory. An attacker could use this flaw to bypass the Address Space Layout Randomization (ASLR) security feature. (CVE-2012-1568, Low)
- A flaw was found in the way the Linux kernel's IPv6 implementation handled overlapping, fragmented IPv6 packets. A remote attacker could potentially use this flaw to bypass protection mechanisms (such as a firewall or intrusion detection system (IDS)) when sending network packets to a target system. (CVE-2012-4444, Low)
The system must be rebooted for this update to take effect.
