Vulnerability Assessment Details

[DSA1212] DSA-1212-1 openssh

Vulnerability Assessment Summary
DSA-1212-1 openssh

Detailed Explanation for this Vulnerability Assessment

Two denial of service problems have been found in the OpenSSH
server. The Common Vulnerabilities and Exposures project identifies the
following vulnerabilities:
The sshd support for ssh protocol version 1 does not properly
handle duplicate incoming blocks. This could permit a remote
attacker to cause sshd to consume significant CPU resources
leading to a denial of service.
A signal handler race condition could potentially permit 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.
