APPLE-SA-2005-06-08 Security Update 2005-006
Security Update 2005-006 is now available and delivers the following
security enhancements:
AFP Server
CVE-ID: CAN-2005-1721
Available for: Mac OS X v10.4.1, Mac OS X Server v10.4.1
Impact: A buffer overflow in support for legacy clients could permit
the running of arbitrary code
Description: The Mac OS X AFP Server supports a number of legacy
clients. A buffer overflow in the support for one of these clients
could permit the running of arbitrary code. This update modifies the
AFP Server to correct this buffer overflow. This issue does not
affect systems prior to Mac OS X 10.4.
AFP Server
CVE-ID: CAN-2005-1720
Available for: Mac OS X v10.4.1, Mac OS X Server v10.4.1
Impact: On an AFP server using an ACL enabled volume for storage,
the copying of a file with POSIX-only permissions can leave an ACL
attached
Description: When copying a local file to an AFP Server that is
using an ACL enabled volume for storage, a temporary ACL is attached
to the remote object during the copy process. This ACL can be left
behind if the file copy was into a directory that was not using ACLs.
The ACL that is left behind could cause confusion as it will
override the POSIX file permissions for the file owner. The ACL does
not permit other users to access the file. This update modifies the
AFP Server so that it correctly removes the ACL that is used for
copying the file. This issue does not affect systems prior to Mac OS
X 10.4.
Bluetooth
CVE-ID: CAN-2005-1333
Available for: Mac OS X v10.4.1, Mac OS X Server v10.4.1, Mac OS X
v10.3.9, Mac OS X Server v10.3.9
Impact: Directory traversal via Bluetooth object exchange
Description: Due to insufficient input checking, the Bluetooth
object exchange services could be used to access files outside of the
default file exchange directory. This update provides an additional
security improvement over the previous release by adding enhanced
filtering for path-delimiting characters. Credit to
kf_lists[at]digitalmunition[dot]com for reporting this issue.
CoreGraphics
CVE-ID: CAN-2005-1722
Available for: Mac OS X v10.4.1, Mac OS X Server v10.4.1
Impact: Applications using either PDFKit or CoreGraphics to render
poorly formed PDF documents could abort due to a NULL pointer
dereference.
Description: If a poorly-formed PDF document is passed to PDFKit or
CoreGraphics for rendering, the rending engine will detect an error
and stop processing. As part of the cleanup process, a check for a
NULL pointer was omitted. This omission can cause an application
that handles PDF documents to abort - requiring that the application
be restarted. CoreGraphics is updated to correctly handle the
cleanup of poorly-formed PDF documents. This issue does not affect
systems prior to Mac OS X 10.4. Credit to Chris Evans for reporting
this issue.
CoreGraphics
CVE-ID: CAN-2005-1726
Available for: Mac OS X v10.4.1, Mac OS X Server v10.4.1
Impact: Console users can gain root privileges
Description: The CoreGraphics Window Server is updated to disallow
unprivileged users from launching commands into root sessions. This
issue does not affect systems prior to Mac OS X v10.4.
Folder Permissions
CVE-ID: CAN-2005-1727
Available for: Mac OS X v10.4.1, Mac OS X Server v10.4.1
Impact: Potential file race condition via world- and group-writable
permissions on two directories
Description: Secure folder permissions are applied to protect the
system's cache folder and the Dashboard system widgets. This
exposure does not exist in systems prior to Mac OS X v10.4. Credit
to Michael Haller at email@hidden for reporting this issue.
launchd
CVE-ID: CAN-2005-1725
Available for: Mac OS X v10.4.1, Mac OS X Server v10.4.1
Impact: The setuid program launchd can allow local privilege
escalation
Description: A vulnerability in launchd allows local users to gain
ownership of arbitrary files. The launchd command is updated to
safely change ownership of files. Credit to Neil Archibald of
Suresec LTD for reporting this issue. This issue does not affect
systems prior to Mac OS X v10.4.
LaunchServices
CVE-ID: CAN-2005-1723
Available for: Mac OS X v10.4.1, Mac OS X Server v10.4.1
Impact: File extensions and mime types marked as unsafe but not
mapped to an Apple UTI could bypass download safety checks
Description: Mac OS X 10.4 contains a database of known unsafe file
extensions and mime types. If an addition to the database of unsafe
types was made, without a corresponding Apple UTI (Uniform Type
Identifier), then a query on certain forms of the file extension or
mime type would not be marked as unsafe. All entries in the current
unsafe type database are mapped to an Apple UTI. This update
corrects the query code to correctly identify unsafe file extensions
and mime types regardless of the presence of an Apple UTI. This
issue does not affect systems prior to Mac OS X 10.4.
MCX Client
CVE-ID: CAN-2005-1728
Available for: Mac OS X v10.4.1, Mac OS X Server v10.4.1
Impact: Portable Home Directory credentials may be available to
local system users
Description: MCX Client is updated to not log portable home
directory mounting credentials. This issue does not affect systems
prior to Mac OS X v10.4.
NFS
CVE-ID: CAN-2005-1724
Available for: Mac OS X v10.4.1, Mac OS X Server v10.4.1
Impact: An NFS export restricted using -network / -mask flags will
export to "everyone"
Description: The use of -network and -mask on a filesystem listed in
the NFS exports file would result in that filesystem being exported
to "everyone". This update modifies the NFS exporting code to
correctly set the network and mask parameters. This issue does not
affect systems prior to Mac OS X 10.4.
PHP
CVE-ID: CAN-2005-0524, CAN-2005-0525, CAN-2005-1042, CAN-2005-1043
Available for: Mac OS X v10.4.1, Mac OS X Server v10.4.1, Mac OS X
v10.3.9, Mac OS X Server v10.3.9
Impact: Multiple vulnerabilities in PHP, including remote denial of
service and execution of arbitrary code
Description: PHP is updated to version 4.3.11 to address several
issues. The PHP release announcement for version 4.3.11 is located at
http://www.php.net/release_4_3_11.php
VPN
CVE-ID: CAN-2005-1343
Available for: Mac OS X v10.4.1, Mac OS X Server v10.4.1
Impact: A local user can obtain root privileges if the system is
being used as a VPN server
Description: A buffer overflow in "vpnd" could be used by a local
user to obtain root privileges if the system is configured as a VPN
server. This problem does not occur on systems that are configured
as a VPN client. This issue cannot be exploited remotely. This
update prevents the buffer overflow from occurring. This issue was
fixed for Mac OS X v10.3.9 via Security Update 2005-005. Credit to
Pieter de Boer of the master SNB at the Universiteit van Amsterdam
(UvA) for reporting this issue.
