Test ID:	1.3.6.1.4.1.25623.1.0.50496
Category:	Ubuntu Local Security Checks
Title:	Ubuntu 4.10 USN-60-0 (linux-source-2.6.8.1)
Summary:	Ubuntu 4.10 USN-60-0 (linux-source-2.6.8.1)
Description:	The remote host is missing an update to linux-source-2.6.8.1 announced via advisory USN-60-0. CVE-2005-0001: Paul Starzetz discovered a race condition in the Linux page fault handler code. This allowed an unprivileged user to gain root privileges on multiprocessor machines under some circumstances. This also affects the Hyper-Threading mode on Pentium 4 processors. http://lists.netsys.com/pipermail/full-disclosure/2005-January/030660.html: Brad Spengler discovered that some device drivers used copy_from_user() (a function to copy data from userspace tools into kernel memory) with insufficient input validation. This potentially allowed users and/or malicious hardware to overwrite kernel memory which could result in a crash (Denial of Service) or even root privilege escalation. Additionally, this update corrects the SMB file system driver. USN-30-1 fixed some vulnerabilities in this driver (see CVE-2004-0883, CVE-2004-0949). However, it was found that these new validation checks were too strict, which cause some valid operations to fail. The following packages are affected: linux-image-2.6.8.1-4-386 linux-image-2.6.8.1-4-686 linux-image-2.6.8.1-4-686-smp linux-image-2.6.8.1-4-amd64-generic linux-image-2.6.8.1-4-amd64-k8 linux-image-2.6.8.1-4-amd64-k8-smp linux-image-2.6.8.1-4-amd64-xeon linux-image-2.6.8.1-4-k7 linux-image-2.6.8.1-4-k7-smp linux-image-2.6.8.1-4-power3 linux-image-2.6.8.1-4-power3-smp linux-image-2.6.8.1-4-power4 linux-image-2.6.8.1-4-power4-smp linux-image-2.6.8.1-4-powerpc linux-image-2.6.8.1-4-powerpc-smp linux-patch-debian-2.6.8.1 Solution: The problem can be corrected by upgrading the affected package to version 2.6.8.1-16.10. In general, a standard system upgrade is sufficient to effect the necessary changes. http://lists.netsys.com/pipermail/full-disclosure/2005-January/030660.html http://lists.ubuntu.com/archives/ubuntu-security-announce/2005-January/000062.html Risk factor : High
