A security issue has been reported in the Linux Kernel, which can be exploited by malicious, local users to bypass certain security restrictions.
The security issue is caused due to the improper enforcing of the "mmap_min_addr" limit. This can be exploited to allocate pages lower than "mmap_min_addr" by expanding the stack or via "do_brk()" in specially crafted binaries.
The security issue affects all 2.6.23 versions.
Solution: Fixed in version 2.6.24-rc5.
Provided and/or discovered by: Reported by the vendor.
