Mac OS X 10.2.5 is now available. It contains fixes for recent
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.
Credit to Dave G. from @stake, Inc. for the discovery of this
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.
