USN-1459-1: Linux kernel (OMAP4) vulnerabilities

First published: Thu May 31 2012(Updated: )

A flaw was found in the Linux kernel's KVM (Kernel Virtual Machine) virtual cpu setup. An unprivileged local user could exploit this flaw to crash the system leading to a denial of service. (CVE-2012-1601) Steve Grubb reported a flaw with Linux fscaps (file system base capabilities) when used to increase the permissions of a process. For application on which fscaps are in use a local attacker can disable address space randomization to make attacking the process with raised privileges easier. (CVE-2012-2123) A flaw was found in how the Linux kernel passed the replacement session keyring to a child process. An unprivileged local user could exploit this flaw to cause a denial of service (panic). (CVE-2012-2745)
