-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ________________________________________________________________________ OpenPKG Security Advisory OpenPKG GmbH http://openpkg.org/security/ http://openpkg.com OpenPKG-SA-2006.032 2006-11-08 ________________________________________________________________________ Package: openssh Vulnerability: security bypass OpenPKG Specific: no Affected Series: Affected Packages: Corrected Packages: E1.0-SOLID <= openssh-4.4p1-E1.0.0 >= openssh-4.4p1-E1.0.1 2-STABLE-20061018 <= openssh-4.4p1-2.20061024 >= openssh-4.5p1-2.20061108 2-STABLE <= openssh-4.4p1-2.20061024 >= openssh-4.5p1-2.20061108 CURRENT <= openssh-4.4p1-20061104 >= openssh-4.5p1-20061108 Description: According to a vendor release announcement [0], a vulnerability exists in the privilege separation functionality of the Secure Shell (SSH) implementation OpenSSH [1]. The vulnerability is caused by an incorrect checking for bad signatures in the sshd(8) privilege separation monitor and this way its verification of successful authentication is weakened. As a result the monitor and the unprivileged process can get out of sync. According to the vendor, this bug is not known to be exploitable in the absence of additional vulnerabilities. Additionally, OpenPKG's OpenSSH configuration for portability reasons has the "privilege separation" functionality not enabled by default. ________________________________________________________________________ References: [0] http://www.openssh.com/txt/release-4.5 [1] http://www.openssh.com/ ________________________________________________________________________ For security reasons, this advisory was digitally signed with the OpenPGP public key "OpenPKG <openpkg@xxxxxxxxxxx>" (ID 63C4CB9F) which you can retrieve from http://openpkg.org/openpkg.org.pgp.
