Ubuntu Update for Linux kernel vulnerabilities USN-618-1

Please Install the Updated Packages.

It was discovered that the ALSA /proc interface did not write the correct number of bytes when reporting memory allocations. A local attacker might be able to access sensitive kernel memory, leading to a loss of privacy. (CVE-2007-4571) Multiple buffer overflows were discovered in the handling of CIFS filesystems. A malicious CIFS server could cause a client system crash or possibly execute arbitrary code with kernel privileges. (CVE-2007-5904) It was discovered that PowerPC kernels did not correctly handle reporting certain system details. By requesting a specific set of information, a local attacker could cause a system crash resulting in a denial of service. (CVE-2007-6694) It was discovered that some device driver fault handlers did not correctly verify memory ranges. A local attacker could exploit this to access sensitive kernel memory, possibly leading to a loss of privacy. (CVE-2008-0007) It was discovered that CPU resource limits could be bypassed. A malicious local user could exploit this to avoid administratively imposed resource limits. (CVE-2008-1294) A race condition was discovered between dnotify fcntl() and close() in the kernel. If a local attacker performed malicious dnotify requests, they could cause memory consumption leading to a denial of service, or possibly send arbitrary signals to any process. (CVE-2008-1375) On SMP systems, a race condition existed in fcntl(). Local attackers could perform malicious locks, causing system crashes and leading to a denial of service. (CVE-2008-1669)
