Mandriva Linux Security Advisory MDVSA-2013:022 http://www.mandriva.com/en/support/security/


Package : openssh Date : March 13, 2013 Affected: Enterprise Server 5.0


Problem Description:

Multiple vulnerabilities has been found and corrected in openssh:

The auth_parse_options function in auth-options.c in sshd in OpenSSH before 5.7 provides debug messages containing authorized_keys command options, which allows remote authenticated users to obtain potentially sensitive information by reading these messages, as demonstrated by the shared user account required by Gitolite. NOTE: this can cross privilege boundaries because a user account may intentionally have no shell or filesystem access, and therefore may have no supported way to read an authorized_keys file in its own home directory (CVE-2012-0814).

The default configuration of OpenSSH through 6.1 enforces a fixed time limit between establishing a TCP connection and completing a login, which makes it easier for remote attackers to cause a denial of service (connection-slot exhaustion) by periodically making many new TCP connections (CVE-2010-5107).

The updated packages have been patched to correct these issues.
