linux-kernel-2.4.19-mips - several vulnerabilities

Several serious problems have been discovered in the Linux kernel.
This update takes care of Linux 2.4.19 for the MIPS architecture. The
Common Vulnerabilities and Exposures project identifies the following
problems that will be fixed with this update:

• CAN-2004-0003
  A vulnerability has been discovered in the R128 DRI driver 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 an attacker could read sensitive data such
  as cryptographic keys 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.

We recommend that you upgrade your kernel packages immediately, either
with a Debian provided kernel or with a self compiled one.
