Denial Of Service (DoS)

kernel is vulnerable to denial of service DoS. The vulnerability exists as a flaw was found in the backported stack unwinder fixes in Red Hat Enterprise Linux 5. On AMD64 and Intel 64 platforms, a local user could trigger this flaw and cause a denial of service...

Arbitrary Code Execution

kernel is vulnerable to arbitrary code execution. A flaw was found in the IA32 system call emulation provided on AMD64 and Intel 64 platforms. An improperly validated 64-bit value could be stored in the %RAX register, which could trigger an out-of-bounds system call table access. An untrusted loc...
