Several local vulnerabilities have been discovered in the Linux kernel that may lead to a denial of service or the execution of arbitrary code. The Common Vulnerabilities and Exposures project identifies the following problems: CVE-2007-6694 Cyrill Gorcunov reported a NULL pointer dereference in code specific to the CHRP PowerPC platforms. Local users could exploit this issue to achieve a Denial of Service (DoS). CVE-2008-0007 Nick Piggin of SuSE discovered a number of issues in subsystems which register a fault handler for memory mapped areas. This issue can be exploited by local users to achieve a Denial of Service (DoS) and possibly execute arbitrary code. CVE-2008-1294 David Peer discovered that users could escape administrator imposed cpu time limitations (RLIMIT_CPU) by setting a limit of 0. CVE-2008-1375 Alexander Viro discovered a race condition in the directory notification subsystem that allows local users to cause a Denial of Service (oops) and possibly result in an escalation of priveleges. For the stable distribution (etch), this problem has been fixed in version 2.6.18.dfsg.1-18etch3. The unstable (sid) and testing distributions will be fixed soon. We recommend that you upgrade your linux-2.6, fai-kernels, and
