-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 - ------------------------------------------------------------------------ Debian Security Advisory DSA-1212-1 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 - -------------------- wget url will fetch the file for you dpkg -i file.deb will install the referenced file. If you are using the apt-get package manager, use the line for sources.list as given below: apt-get update will update the internal database 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.
