Test ID:1.3.6.1.4.1.25623.1.0.57613
Category:Mandrake Local Security Checks
Title:Mandrake Security Advisory MDKSA-2006:179 (openssh)
Summary:Mandrake Security Advisory MDKSA-2006:179 (openssh)
Description:
The remote host is missing an update to openssh
announced via advisory MDKSA-2006:179.

Tavis Ormandy of the Google Security Team discovered a Denial of
Service vulnerability in the SSH protocol version 1 CRC compensation
attack detector. This could allow a remote unauthenticated attacker to
trigger excessive CPU utilization by sending a specially crafted SSH
message, which would then deny ssh services to other users or processes
(CVE-2006-4924, CVE-2006-4925). Please note that Mandriva ships with
only SSH protocol version 2 enabled by default.

Next, an unsafe signal handler was found by Mark Dowd. This signal
handler was vulnerable to a race condition that could be exploited to
perform a pre-authentication DoS, and theoretically a
pre-authentication remote code execution in the case where some
authentication methods like GSSAPI are enabled (CVE-2006-5051).

Updated packages have been patched to correct this issue.

Affected: 2006.0, 2007.0, Corporate 3.0, Corporate 4.0,
Multi Network Firewall 2.0


Solution:
To upgrade automatically use MandrakeUpdate or urpmi. The verification
of md5 checksums and GPG signatures is performed automatically for you.
