openssh

Two denial of service problems have been found in the OpenSSH
server. The Common Vulnerabilities and Exposures project identifies the
following vulnerabilities:

• CVE-2006-4924
  The sshd support for ssh protocol version 1 does not properly
  handle duplicate incoming blocks. This could allow a remote
  attacker to cause sshd to consume significant CPU resources
  leading to a denial of service.
• CVE-2006-5051
  A signal handler race condition could potentially allow a remote
  attacker to crash sshd and could theoretically lead to the
  ability to execute arbitrary code.

For the stable distribution (sarge), these problems have been fixed in
version 1:3.8.1p1-8.sarge.6.

For the unstable and testing distributions, these problems have been
fixed in version 1:4.3p2-4.

We recommend that you upgrade your openssh package.
