APPLE-SA-2005-01-25 Security Update 2005-001

Security Update 2005-001 is now available and delivers the following
security enhancements:

at commands
Available for:  Mac OS X v10.3.7, Mac OS X Server v10.3.7
CVE-ID:  CAN-2005-0125
Impact:  Updates the "at" commands to address a local privilege
escalation vulnerability
Description:  The "at" family of commands did not properly drop
privileges.  This could allow a local user to remove files not owned
by them, run programs with added privileges, or read the contents of
normally unreadable files.  This update patches the commands at,
atrm, batch, atq, and atrun.  Credit to
kf_lists[at]digitalmunition[dot]com for reporting this issue.

ColorSync
Available for:  Mac OS X v10.3.7, Mac OS X Server v10.3.7, Mac OS X
v10.2.8, Mac OS X Server v10.2.8
CVE-ID:  CAN-2005-0126
Impact:  Malformed ICC color profiles could overwrite the program
heap resulting in arbitrary code execution.
Description:  An out-of-specification or improperly embedded ICC
color profile could overwrite the program heap and allow arbitrary
code execution.  There are no known exploits for this issue.  With
this update, ColorSync will reject incorrectly-formed ICC color
profiles.

libxml2
Available for:  Mac OS X v10.3.7, Mac OS X Server v10.3.7
CVE-ID:  CAN-2004-0989
Impact:  The libxml2 library contains unsafe code that may be
exploited in applications linked against it.
Description:  This update fixes several functions in the libxml2
library that have been identified as unsafe due to potentially
exploitable buffer overflows.

Mail
Available for:  Mac OS X v10.3.7 Client, Mac OS X Server v10.3.7
CVE-ID:  CAN-2005-0127
Impact:  Email messages sent from a single machine can be identified
Description:  A GUUID containing an identifier associated with the
ethernet networking hardware was used in the construction an RFC-822
required Message-ID header.  Mail now hides this information by
computing the Message-ID using a cryptographic hash of the GUUID
concatenated with data from /dev/random.  Credit to Carl Purvis for
reporting this issue.

PHP
Available for:  Mac OS X v10.3.7, Mac OS X Server v10.3.7, Mac OS X
v10.2.8, Mac OS X Server v10.2.8
CVE-ID:  CAN-2003-0860, CAN-2003-0863, CAN-2004-0594, CAN-2004-0595,
CAN-2004-1018, CAN-2004-1019, CAN-2004-1020, CAN-2004-1063,
CAN-2004-1064, CAN-2004-1065
Impact:  Multiple vulnerabilities in PHP including remote denial of
service and execution of arbitrary code
Description:  PHP is updated to version 4.3.10 to address several
issues.  The PHP release announcement for version 4.3.10 is located
at http://www.php.net/release_4_3_10.php

Safari
Available for:  Mac OS X v10.3.7, Mac OS X Server v10.3.7, Mac OS X
v10.2.8, Mac OS X Server v10.2.8
CVE-ID:  CAN-2004-1314
Impact:  When Safari's "Block Pop-Up Windows" feature is not enabled,
a malicious pop-up window could appear as being from a trusted site
Description:  If the "Block Pop-Up Windows" feature is enabled, then
this issue does not occur.  If the "Block Pop-Up Windows" feature is
not enabled, a user can be misled about the content of a Pop-up
window if they used an untrusted link to navigate to a site they
wanted to view.  This update corrects the issue regardless of the
"Block Pop-Up Windows" setting.  Credit to Secunia Research for
reporting this issue.

SquirrelMail
Available for:  Mac OS X Server 10.3.7
CVE-ID:  CAN-2004-1036
Impact:  SquirrelMail is updated to address a cross-site scripting
