CVE-2009-0029 Information

Description

The ABI in the Linux kernel 2.6.28 and earlier on s390 powerpc sparc64 and mips 64-bit platforms requires that a 32-bit argument in a 64-bit register was properly sign extended when sent from a user-mode application but cannot verify this which allows local users to cause a denial of service (crash) or possibly gain privileges via a crafted system call.
