0acf6967795b6e572efa6fa96bc8daa4c48aa9762c583cd6ee70d852449a6d06Ubuntu Security Notice 614-1 - 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. 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. 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. The tehuti network driver did not correctly handle certain IO functions. A local attacker could perform malicious requests to the driver, potentially accessing kernel memory, leading to privilege escalation or access to private system information.

b348d7056d7c7999326caf977e83f0e7f35795711a865d85e90ae265f9a90eb3Debian Security Advisory 1565-1 - Several local vulnerabilities have been discovered in the Linux kernel that may lead to a denial of service or the execution of arbitrary code. 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). 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. David Peer discovered that users could escape administrator imposed cpu time limitations (RLIMIT_CPU) by setting a limit of 0. 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 privileges.
