Hash: SHA1

Mac OS X 10.2.5 is now available.  It contains fixes for recent
vulnerabilities in:

Apache 2.0:  Fixes CAN-2003-0132, a denial of service vulnerability in
    Apache 2.0 versions through 2.0.44.  Apache 2.0 is distributed only
    with Mac OS X Server, and is not enabled by default.

Directory Services:  Fixes CAN-2003-0171 DirectoryServices Privilege
    Escalation and DoS Attack.  DirectoryServices is part of the Mac OS
    X and Mac OS X Server information services subsystem.  It is
    launched at startup, setuid root and installed by default.  It is
    possible for a local attacker to modify an environment variable
    that would allow the execution of arbitrary commands as root.

File Sharing/Service:  Fixes CAN-2003-0198 where the contents of the
    write-only DropBox folder can be revealed.  When enabled, Personal
    File Sharing on Mac OS X or Apple File Service on Mac OS X Server,
    a "DropBox" folder is available by default to allow people to
    deposit files.   This update no longer allows the permissions of
    the "DropBox" folder to be changed by a guest.

OpenSSL:  Fixes CAN-2003-0131 Klima-Pokorny-Rosa attack on PKCS #1 v1.5
    padding.  The patch from the OpenSSL team, which addresses this
    vulnerability, is applied to Mac OS X and Mac OS X Server.

Samba:  Fixes CAN-2003-0201 which could allow an anonymous user to gain
    remote root access due to a buffer overflow.  The built-in Windows
    file sharing is based on the open source technology called Samba
    and is off by default in Mac OS X.

sendmail:  Fixes CAN-2003-0161, where address parsing code in sendmail
    does not adequately check the length of email addresses.  Only the
    patch from the sendmail team is applied to the currently-shipping
    version of sendmail in Mac OS X and Mac OS X Server.
