Debian: kernel 2.4.16 Multiple vulnerabilities
Summary
Several serious problems have been discovered in the Linux kernel.
This update takes care of Linux 2.4.16 for the ARM architecture. The
Common Vulnerabilities and Exposures project identifies the following
problems that will be fixed with this update:
CAN-2003-0127
The kernel module loader allows local users to gain root
privileges by using ptrace to attach to a child process that is
spawned by the kernel
CAN-2004-0003
A vulnerability has been discovered in the R128 drive in the Linux
kernel which could potentially lead an attacker to gain
unauthorised privileges. Alan Cox and Thomas Biege developed a
correction for this
CAN-2004-0010
Arjan van de Ven discovered a stack-based buffer overflow in the
ncp_lookup function for ncpfs in the Linux kernel, which could
lead an attacker to gain unauthorised privileges. Petr Vandrovec
developed a correction for this.
CAN-2004-0109
zen-parse discovered a buffer overflow vulnerability in the
ISO9660 filesystem component of Linux kernel which could be abused
by an attacker to gain unauthorised root access. Sebastian
Krahmer and Ernie Petrides developed a correction for this.
CAN-2004-0177
Solar Designer discovered an information leak in the ext3 code of
Linux. In a worst case a local attacker could obtain sensitive
information (such as cryptographic keys in another worst case)
which would otherwise never hit disk media. Theodore Ts'o
developed a correction for this.
CAN-2004-0178
Andreas Kies discovered a denial of service condition in the Sound
Blaster driver in Linux. He also developed a correction for this.
These problems are also fixed by upstream in Linux 2.4.26 and will be
fixed in Linux 2.6.6.
The following security matrix explains which kernel versions for which
architectures are already fixed and which will be removed instead.
Architecture stable (woody) unstable (sid)
source 2.4.16-1woody2 2.4.25-3
arm/patch 20040419 20040316
arm/lart 20040419 2.4.25-4
arm/netwinder 20040419 2.4.25-4
arm/riscpc 20040419 2.4.25-4
We recommend that you upgrade your kernel packages immediately, either
with a Debian provided kernel or with a self compiled one.
