Tip: For more information about CVE-IDs referenced below, see (http://www.cve.mitre.org/).
Component: Apache 2
CVE-IDs: CAN-2004-0493, CAN-2004-0488
Available for: Mac OS X Server 10.2.8, Mac OS X Server 10.3.4, Mac OS X Server 10.3.5
Impact: Exposure to a potential Denial of Service.
Description: The Apache Organization has released Apache version
2.0.50. This release fixes a number of denial of service
vulnerabilities. We have updated Apache to version 2.0.50 which only
ships with Mac OS X Server, and is off by default.
Component: CoreFoundation
CVE-ID: CAN-2004-0821
Available for: Mac OS X 10.2.8, Mac OS X 10.3.4, Mac OS X 10.3.5, Mac
OS X Server 10.2.8, Mac OS X Server 10.3.4, Mac OS X Server 10.3.5
Impact: Privileged programs using CoreFoundation can be made to load a user supplied library.
Description: Bundles using the CoreFoundation CFPlugIn facilities can
include directions to automatically load plugin executables. With a
specially crafted bundle this could also occur for privileged programs,
permitting a local privilege escalation. CoreFoundation now prevents
automatic executable loading for bundles that already have a loaded
executable. Credit to Kikuchi Masashi for
reporting this issue.
Component: CoreFoundation
CVE-ID: CAN-2004-0822
Available for: Mac OS X 10.2.8, Mac OS X 10.3.4, Mac OS X 10.3.5, Mac
OS X Server 10.2.8, Mac OS X Server 10.3.4, Mac OS X Server 10.3.5
Impact: An environment variable can be manipulated to cause a buffer overflow which can result in a privilege escalation
Description: By manipulating local environment variables a program
could potentially be leveraged by a local attacker to execute arbitrary
code. This can only be exploited with access to a local account.
Validity checks for local environment variables are now provided.

Component: IPSec
CVE-ID: CAN-2004-0607
Available for: Mac OS X 10.2.8, Mac OS X 10.3.4, Mac OS X 10.3.5, Mac
OS X Server 10.2.8, Mac OS X Server 10.3.4, Mac OS X Server 10.3.5
Impact: When using certificates, unauthenticated hosts may be able to negotiate an IPSec connection.
Description: When configured to use X.509 certificates to authenticate
remote hosts, a certificate verification failure does not abort the key
exchange. Mac OS X does not use certificates for IPSec by default so
this issue only affects configurations that have been manually
configured. IPSec now verifies and aborts a key exchange if a
certificate verification failure occurs.
Component: Kerberos
CVE-ID: CAN-2004-0523
Available for: Mac OS X 10.2.8, Mac OS X 10.3.4, Mac OS X 10.3.5, Mac
OS X Server 10.2.8, Mac OS X Server 10.3.4, Mac OS X Server 10.3.5
Impact: Multiple buffer overflows in krb5_aname_to_localname for MIT
Kerberos 5 (krb5) 1.3.3 and earlier could permit remote attackers to
execute arbitrary code.
Description: The buffer overflow can only be exploited if
"auth_to_local_names" or "auth_to_local" support is also configured in
the edu.mit.Kerberos file. Apple does not enable this by default. The
security fix was back ported and applied to the Mac OS X versions of
Kerberos. The Mac OS X and Mac OS X Server version of Kerberos is not
susceptible to the recent "double-free" issue reported in the CERT
vulnerability note VU#350792 (CAN-2004-0772). Credit to the MIT
Kerberos Development Team for informing us of this issue.
Component: lukemftpd
CVE-ID: CAN-2004-0794
Available for: Mac OS X 10.2.8, Mac OS X 10.3.4, Mac OS X 10.3.5, Mac
OS X Server 10.2.8, Mac OS X Server 10.3.4, Mac OS X Server 10.3.5
Impact: A race condition that can permit an authenticated remote attacker to cause a denial of service or execute arbitrary code
Description: If the FTP service has been enabled, and a remote attacker
can correctly authenticate, then a race condition would permit them to
stop the FTP service or execute arbitary code. The fix is to replace
the lukemftpd FTP service with tnftpd. lukemftp is installed but not
activated in Mac OS X Server, which instead uses xftp. Credit to Luke
Mewburn of the NetBSD Foundation for informing us of this issue.
Component: OpenLDAP
CVE-ID: CAN-2004-0823
Available for: Mac OS X 10.3.4, Mac OS X 10.3.5, Mac OS X Server 10.3.4, Mac OS X Server 10.3.5
Impact: A crypt password can be used as if it were a plain text password.
Description: Backwards compatibility with older LDAP implementations
permits the storing of a crypt password in the userPassword attribute.
Some authentication validation schemes can use this value as if it were
a plain text password. The fix removes the ambiguity and always uses
this type of field as a crypt password. This issue does not occur in
Mac OS X 10.2.8. Credit to Steve Revilak of Kayak Software Corporation
for reporting this issue.
Component: OpenSSH
CVE-ID: CAN-2004-0175
Available for: Mac OS X 10.2.8, Mac OS X 10.3.4, Mac OS X 10.3.5, Mac
OS X Server 10.2.8, Mac OS X Server 10.3.4, Mac OS X Server 10.3.5
Impact: A malicious ssh/scp server can overwrite local files
Description: A directory traversal vulnerability in the scp program
permits a malicious remote server to overwrite local files. The
security fix was backported and applied to the Mac OS X versions of
OpenSSH.
Component: PPPDialer
CVE-ID: CAN-2004-0824
Available for: Mac OS X 10.2.8, Mac OS X 10.3.4, Mac OS X 10.3.5, Mac
OS X Server 10.2.8, Mac OS X Server 10.3.4, Mac OS X Server 10.3.5
Impact: A malicious user can overwrite system files resulting in a local privilege escalation
Description: PPP components performed insecure accesses of a file
stored in a world-writeable location. The fix moves the log files to a
non-world-writeable location.
Component: QuickTime Streaming Server
Available for: Mac OS X Server 10.2.8, Mac OS X Server 10.3.4, Mac OS X Server 10.3.5
CVE-ID: CAN-2004-0825
Impact: A denial of service requiring a restart of the QuickTime Streaming Server
Description: A particular sequence of client operations can cause a
deadlock on the QuickTime Streaming Server. The fix updates the code to
eliminate this deadlock condition.
Component: rsync
CVE-ID: CAN-2004-0426
Available for: Mac OS X 10.2.8, Mac OS X 10.3.4, Mac OS X 10.3.5, Mac
OS X Server 10.2.8, Mac OS X Server 10.3.4, Mac OS X Server 10.3.5
Impact: When rsync is run in daemon mode a remote attacker can write
outside of the module path unless the chroot option has been set.
Description: rsync before version 2.6.1 does not properly sanitize
paths when running a read/write daemon with the chroot option turned
off. The fix updates rsync to version 2.6.2.
Component: Safari
CVE-ID: CAN-2004-0361
Available for: Mac OS X 10.2.8, Mac OS X Server 10.2.8
Impact: A JavaScript array of negative size can cause Safari to access out of bounds memory resulting in an application crash.
Description: Storing objects into a JavaScript array allocated with
negative size can overwrite memory. Safari now stops processing
JavaScript programs if an array allocation fails.
This security enhancement was previously made available in Safari
1.0.3, and is being applied inside the Mac OS X 10.2.8 operating system
as an extra layer of protection for customers who have not installed
that version of Safari. This is a specific fix for Mac OS X 10.2.8 and
the issue does not exist in Mac OS X 10.3 or later systems.
Component: Safari
CVE-ID: CAN-2004-0720
Available for: Mac OS X 10.2.8, Mac OS X 10.3.4, Mac OS X 10.3.5, Mac
OS X Server 10.2.8, Mac OS X Server 10.3.4, Mac OS X Server 10.3.5
Impact: An untrusted web site can inject content into a frame intended to be used by another domain.
Description: A web site that uses multiple frames can have some of its
frames replaced with content from a malicious site if the malicious
site is visited first. The fix imposes a set of parent/child rules
preventing the attack.
Component: SquirrelMail
CVE-ID: CAN-2004-0521
Available for: Mac OS X 10.2.8, Mac OS X 10.3.4, Mac OS X 10.3.5, Mac
OS X Server 10.2.8, Mac OS X Server 10.3.4, Mac OS X Server 10.3.5
Impact: SquirrelMail before 1.4.3 RC1 allows remote attackers to execute unauthorized SQL statements
Description: SquirrelMail before 1.4.3 RC1 is vulnerable to SQL
injection which permits unauthorized SQL statements to be run. The fix
updates SquirrelMail to version 1.4.3a
Component: tcpdump
CVE-IDs: CAN-2004-0183, CAN-2004-0184
Available for: Mac OS X 10.2.8, Mac OS X 10.3.4, Mac OS X 10.3.5, Mac
OS X Server 10.2.8, Mac OS X Server 10.3.4, Mac OS X Server 10.3.5
Impact: Maliciously crafted packets can cause a crash of a running tcpdump
Description: The detailed printing functions for ISAKMP packets do not
perform correct bounds checking and cause an out-of-bounds read which
results in a crash. The fix updates tcpdump to version 3.8.3.
