Description:
Wojciech Purczynski has reported a vulnerability in the Linux kernel, which can be exploited by malicious, local users to gain escalated privileges.
The vulnerability is caused due to the kernel not zero-extending x86_64 registers after ptrace in the 32bit entry path in arch/x86_64/ia32/ia32entry.S on x86_64 platforms.
The vulnerability is reported in versions prior to 2.4.35.3 and 2.6.22.7.
Note: A problem in the ATM module, which can cause a kernel panic, has also been reported by Gilles Espinasse.
