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-2009-0029 Christian Borntraeger discovered an issue effecting the alpha, mips, powerpc, s390 and sparc64 architectures that allows local users to cause a denial of service or potentially gain elevated privileges. CVE-2009-0031 Vegard Nossum discovered a memory leak in the keyctl subsystem that allows local users to cause a denial of service by consuming all of kernel memory. CVE-2009-0065 Wei Yongjun discovered a memory overflow in the SCTP implementation that can be triggered by remote users. CVE-2009-0269 Duane Griffin provided a fix for an issue in the eCryptfs subsystem which allows local users to cause a denial of service . CVE-2009-0322 Pavel Roskin provided a fix for an issue in the dell_rbu driver that allows a local user to cause a denial of service by reading 0 byts from a sysfs entry. CVE-2009-0676 Clement LECIGNE discovered a bug in the sock_getsockopt function that may result in leaking sensitive kernel memory. CVE-2009-0675 Roel Kluin discovered inverted logic in the skfddi driver that permits local, unprivileged users to reset the driver statistics. CVE-2009-0745 Peter Kerwien discovered an issue in the ext4 filesystem that allows local users to cause a denial of service during a resize operation. CVE-2009-0746 Sami Liedes reported an issue in the ext4 filesystem that allows local users to cause a denial of service when accessing a specially crafted corrupt filesystem. CVE-2009-0747 David Maciejak reported an issue in the ext4 filesystem that allows local users to cause a denial of service when mounting a specially crafted corrupt filesystem. CVE-2009-0748 David Maciejak reported an additional issue in the ext4 filesystem that allows local users to cause a denial of service when mounting a specially crafted corrupt filesystem. For the stable distribution , these problems have been fixed in version 2.6.26-13lenny2. For the oldstable distribution , these problems, where applicable, will be fixed in future updates to linux-2.6 and linux-2.6.24. We recommend that you upgrade your linux-2.6 packages.
