USN37-1 : cyrus21-imapd vulnerability |

cyrus21-imapd vulnerability Detailed Explanation for this Vulnerability Assessment Summary : These remote packages are missing security patches : - cyrus21-admin - cyrus21-clients - cyrus21-common - cyrus21-dev - cyrus21-doc - cyrus21-imapd - cyrus21-murder - cyrus21-pop3d - libcyrus-imap-perl21 Description : Recently another buffer overflow has been discovered in the SASL authentication module of the Cyrus IMAP server. An off-by-one comparison error in the mysasl_canon_user() function could lead to a missing termination of an user name string. This vulnerability could permit remote, attacker-supplied machine code to be executed in the context of the affected server process. Since the IMAP server usually runs as unprivileged user 'cyrus', there is no possibility of root privilege escalation. Solution : Upgrade to : - cyrus21-admin-2.1.16-6ubuntu0.2 (Ubuntu 4.10) - cyrus21-clients-2.1.16-6ubuntu0.2 (Ubuntu 4.10) - cyrus21-common-2.1.16-6ubuntu0.2 (Ubuntu 4.10) - cyrus21-dev-2.1.16-6ubuntu0.2 (Ubuntu 4.10) - cyrus21-doc-2.1.16-6ubuntu0.2 (Ubuntu 4.10) - cyrus21-imapd-2.1.16-6ubuntu0.2 (Ubuntu 4.10) - cyrus21-murder-2.1.16-6ubuntu0.2 (Ubuntu 4.10) - cyrus21-pop3d-2.1.16-6ubuntu0.2 (Ubuntu 4.10) - libcyrus-imap-perl21-2.1.16-6ubuntu0.2 (Ubuntu 4.10) Network Security Threat Level: High Networks Security ID: Vulnerability Assessment Copyright: Ubuntu Security Notice (C) 2005 Canonical, Inc. / NASL script (C) 2005 Michel Arboi |
