Microsoft Security Advisory (961509): Research proves feasibility of collision attack
Revision Note: Advisory published Advisory Summary:Microsoft is aware that research was published at a security conference proving a successful attack against X.509 digital certificates signed using the MD5 hashing algorithm. This attack method would allow an attacker to generate additional digital certificates with different content that have the same digital signature as an original certificate. The MD5 algorithm had previously shown a vulnerability, but a practical attack had not yet been demonstrated.

AUDIT_WARN(5)						      BSD File Formats Manual						     AUDIT_WARN(5)

NAME

     audit_warn -- alert when audit daemon issues warnings

DESCRIPTION

     The audit_warn script runs when auditd(8) generates warning messages.

     The default audit_warn is a script whose first parameter is the type of warning; the script appends its arguments to
     /etc/security/audit_messages.  Administrators may replace this script: a more comprehensive one would take different actions based on the
     type of warning.  For example, a low-space warning could result in an email message being sent to the administrator.

FILES

     /etc/security/audit_warn
     /etc/security/audit_messages

SEE ALSO

     audit(4), auditd(8)

HISTORY

     The OpenBSM implementation was created by McAfee Research, the security division of McAfee Inc., under contract to Apple Computer Inc. in
     2004.  It was subsequently adopted by the TrustedBSD Project as the foundation for the OpenBSM distribution.
