Debian: DSA-1592-1 Urgent: Risk of Kernel Heap Overflow Vulnerability

Wei Wang from McAfee reported a potential heap overflow in the
ASN.1 decode code that is used by the SNMP NAT and CIFS
subsystem. Exploitation of this issue may lead to arbitrary code
execution. This issue is not believed to be exploitable with the
pre-built kernel images provided by Debian, but it might be an
issue for custom images built from the Debian-provided source
package.

CVE-2008-2358

Brandon Edwards of McAfee Avert labs discovered an issue in the
DCCP subsystem. Due to missing feature length checks it is possible
to cause an overflow they may result in remote arbitrary code
execution.

For the stable distribution (etch), this problem has been fixed in
version 2.6.18.dfsg.1-18etch6.

The linux-2.6/mipsel build was not yet available at the time of this
advisory. This advisory will be updated when this this build becomes
available.

We recommend that you upgrade your linux-2.6, fai-kernels, and
user-mode-linux packages.
