Vulnerability Insight:
Several vulnerabilities have been discovered in the Linux kernel that may lead to denial of service, privilege escalation, or information leak. The Common Vulnerabilities and Exposures project identifies the following problems:
CVE-2008-4307
Bryn M. Reeves reported a denial of service in the NFS filesystem. Local users can trigger a kernel BUG() due to a race condition in the do_setlk function.
CVE-2008-5395
Helge Deller discovered a denial of service condition that allows local users on PA-RISC to crash the system by attempting to unwind a stack containing userspace addresses.
CVE-2008-5701
Vlad Malov reported an issue on 64-bit MIPS where a local user could cause a system crash by crafting a malicious binary which makes o32 syscalls with a number less than 4000.
CVE-2008-5702
Zvonimir Rakamaric reported an off-by-one error in the ib700wdt watchdog driver which allows local users to cause a buffer underflow by making a specially crafted WDIOC_SETTIMEOUT ioctl call.
CVE-2008-5713
Flavio Leitner discovered that a local user can cause a denial of service by generating large amounts of traffic on a large SMP system, resulting in soft lockups.
CVE-2009-0028
Chris Evans discovered a situation in which a child process can send an arbitrary signal to its parent.
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 available kernel memory.
CVE-2009-0065
Wei Yongjun discovered a memory overflow in the SCTP implementation that can be triggered by remote users, permitting remote code execution.
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 (oops) by reading 0 bytes from a sysfs entry.
CVE-2009-0675
Roel Kluin discovered inverted logic in the skfddi driver that permits local, unprivileged users to reset the driver statistics.
CVE-2009-0676
Clement LECIGNE discovered a bug in the sock_getsockopt function that may result in leaking sensitive kernel memory.
CVE-2009-0834
Roland McGrath discovered an issue on amd64 kernels that allows local users to circumvent system call audit configurations which filter based on the syscall numbers or argument details.
CVE-2009-0859
Jiri Olsa discovered that a local user can cause a denial of service (system hang) using a SHM_INFO shmctl call on kernels compiled with CONFIG_SHMEM disabled. This issue does not affect prebuilt Debian kernels.
CVE-2009-1192
Shaohua Li reported an issue in the AGP subsystem that may allow local users to read sensitive kernel memory due to a leak of uninitialized memory.
CVE-2009-1265
