More information:

Several vulnerabilities have been discovered in the Linux kernel that may lead to a denial of service, privilege escalation or a leak of sensitive data. The Common Vulnerabilities and Exposures project identifies the following problems:

  • CVE-2008-1514

    Jan Kratochvil reported a local denial of service vulnerability in the ptrace interface for the s390 architecture. Local users can trigger an invalid pointer dereference, leading to a system panic.

  • CVE-2008-3525

    Eugene Teo reported a lack of capability checks in the kernel driver for Granch SBNI12 leased line adapters (sbni), allowing local users to perform privileged operations.

  • CVE-2008-3831

    Olaf Kirch discovered an issue with the i915 driver that may allow local users to cause memory corruption by use of an ioctl with insufficient privilege restrictions.

  • CVE-2008-4113/CVE-2008-4445

    Eugene Teo discovered two issues in the SCTP subsystem which allow local users to obtain access to sensitive memory when the SCTP-AUTH extension is enabled.

For the stable distribution (etch), these problems have been fixed in version 2.6.24-6~etchnhalf.6.

We recommend that you upgrade your linux-2.6.24 packages.

Fixed in:

Debian GNU/Linux 4.0 (etch)
