Subject: [USN-57-1] Linux kernel vulnerabilities
===========================================================
Ubuntu Security Notice USN-57-1 January 09, 2005
linux-source-2.6.8.1 vulnerabilities
CAN-2004-1235, CAN-2004-1337
===========================================================
A security issue affects the following Ubuntu releases:
Ubuntu 4.10 (Warty Warthog)
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
The problem can be corrected by upgrading the affected package to
version 2.6.8.1-16.8. In general, a standard system upgrade is
sufficient to effect the necessary changes.
Details follow:
Paul Starzetz discovered a race condition in the ELF library and a.out
binary format loaders, which can be locally exploited in several
different ways to gain root privileges. (CAN-2004-1235)
Liang Bin found a design flaw in the capability module. After this
module was loaded on demand in a running system, all unprivileged user
space processes got all kernel capabilities (thus essentially root
privileges). This is mitigated by the fact that the capability module
is loaded very early in the boot process of a standard Ubuntu system,
when no unprivileged user processes are yet running. (CAN-2004-1337)
Finally, this update fixes a memory leak in the ip_conntrack_ftp
iptables module. However, it is believed that this is not exploitable.
