 Mandriva Linux Security Advisory                         MDVSA-2013:022

 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.
