CVE-2009-0029

Publication date 15 January 2009

Last updated 24 July 2024

Ubuntu priority

Medium

Why this priority?

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.

From the Ubuntu Security Team

The 64-bit syscall interfaces did not correctly handle sign extension. A local attacker could make malicious syscalls, possibly gaining root privileges. The x86_64 architecture was not affected.
