After a standard system upgrade you need to reboot your computer to affect the necessary changes.

Details follow:

Evan Teran discovered that the Linux kernel ptrace routines did not correctly handle certain requests robustly. Local attackers could exploit this to crash the system, causing a denial of service. (CVE-2007-3731)

It was discovered that hugetlb kernels on PowerPC systems did not prevent the stack from colliding with reserved kernel memory. Local attackers could exploit this and crash the system, causing a denial of service. (CVE-2007-3739)

It was discovered that certain CIFS filesystem actions did not honor the umask of a process. Local attackers could exploit this to gain additional privileges. (CVE-2007-3740)

Wojciech Purczynski discovered that the Linux kernel ia32 syscall emulation in x86_64 kernels did not correctly clear the high bits of registers. Local attackers could exploit this to gain root privileges. (CVE-2007-4573)

Title: The Linux kernel 2.6.20 and 2.6.21 does not properly handle an invalid LDT segment selector in %cs (the xcs field) during ptrace single-step operations, which allows local users to cause a denial of service (NULL dereference and OOPS) via certain code that makes ptrace PTRACE_SETREGS and PTRACE_SINGLESTEP requests, related to the TRACE_IRQS_ON function, and possibly related to the arch_ptrace function.
