-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1

Debian Security Advisory DSA-1212-1 security@...ian.org
http://www.debian.org/security/ Noah Meyerhans
November 15, 2006
- ------------------------------------------------------------------------
Package : openssh (1:3.8.1p1-8.sarge.6)
Vulnerability : Denial of service
Problem type : remote
Debian-specific: no
CVE Id(s) : CVE-2006-4924 CVE-2006-5051
BugTraq ID : 20216 20241
Debian Bug : 392428
Two denial of service vulnerabilities have been found in the OpenSSH
server.
CVE-2006-4924
The sshd support for ssh protcol 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.
Upgrade instructions
- --------------------

apt-get upgrade
will install corrected packages
You may use an automated update by adding the resources from the
footer to the proper configuration.
Debian 3.1 (stable)
- -------------------
Stable updates are available for alpha, amd64, arm, hppa, i386, ia64, m68k, mips, mipsel, powerpc, s390 and sparc.
