Description :

A Denial of Service vulnerability was discovered in the
sys_set_mempolicy() function. By calling the function with a negative
first argument, a local attacker could cause a kernel crash.
(CVE-2005-3053)

A race condition was discovered in the handling of shared memory
mappings with CLONE_VM. A local attacker could exploit this to cause a
deadlock (Denial of Service) by triggering a core dump while waiting
for a thread which had just performed an exec() system call.
(CVE-2005-3106)

A race condition was found in the handling of traced processes. When
one thread was tracing another thread that shared the same memory map,
a local attacker could trigger a deadlock (Denial of Service) by
forcing a core dump when the traced thread was in the TASK_TRACED
state. (CVE-2005-3107)

A vulnerability has been found in the "ioremap" module. By performing
certain IO mapping operations, a local attacker could either read
memory pages he has not normally access to (information leak) or cause
a kernel crash (Denial of Servic
