Mandriva Linux Security Advisory 2013-022 - 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. 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 by periodically making many new TCP connections. The updated packages have been patched to correct these issues.

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.
