 Mandriva Linux Security Advisory                         MDKSA-2006:179
 http://www.mandriva.com/security/
 _______________________________________________________________________
 
 Package : openssh
 Date    : October 3, 2006
 Affected: 2006.0, 2007.0, Corporate 3.0, Corporate 4.0,
           Multi Network Firewall 2.0
 _______________________________________________________________________
 
 Problem Description:
 
 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.
