CVE-2010-3081: Buffer Overflow
First published: Thu Sep 16 2010(Updated: )
Description of problem: A vulnerability in the 32-bit compatibility layer for 64-bit systems was reported. It is caused by insecure allocation of user space memory when translating system call inputs to 64-bit. A stack pointer underflow can occur when using the "compat_alloc_user_space" method with an arbitrary length input.
