DSA-2389-1 linux-2.6 -- privilege escalation/denial of service/information leak  

Several vulnerabilities have been discovered in the Linux kernel that may lead to a denial of service or privilege escalation. The Common Vulnerabilities and Exposures project identifies the following problems: CVE-2011-2183 Andrea Righi reported an issue in KSM, a memory-saving de-duplication feature. By exploiting a race with exiting tasks, local users can cause a kernel oops, resulting in a denial of service. CVE-2011-2213 Dan Rosenberg discovered an issue in the INET socket monitoring interface. Local users could cause a denial of service by injecting code and causing the kernel to execute an infinite loop. CVE-2011-2898 Eric Dumazet reported an information leak in the raw packet socket implementation. CVE-2011-3353 Han-Wen Nienhuys reported a local denial of service issue issue in the FUSE support in the linux kernel. Local users could cause a buffer overflow, leading to a kernel oops and resulting in a denial of service. CVE-2011-4077 Carlos Maiolino reported an issue in the XFS filesystem. A local user with the ability to mount a filesystem could corrupt memory resulting in a denial of service or possibly gain elevated privileges. CVE-2011-4110 David Howells reported an issue in the kernel's access key retention system which allow local users to cause a kernel oops leading to a denial of service. CVE-2011-4127 Paolo Bonzini of Red Hat reported an issue in the ioctl passthrough support for SCSI devices. Users with permission to access restricted portions of a device can obtain access to the entire device by way of the SG_IO ioctl. This could be exploited by a local user or privileged VM guest to achieve a privilege escalation. CVE-2011-4611 Maynard Johnson reported an issue with the perf support on POWER7 systems that allows local users to cause a denial of service. CVE-2011-4622 Jan Kiszka reported an issue in the KVM PIT timer support. Local users with the permission to use KVM can cause a denial of service by starting a PIT timer without first setting up the irqchip. CVE-2011-4914 Ben Hutchings reported various bounds checking issues within the ROSE protocol support in the kernel. Remote users could possibly use this to gain access to sensitive memory or cause a denial of service.
