site_archiver@lists.apple.com Delivered-To: security-announce@lists.apple.com -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 APPLE-SA-2006-08-01 Security Update 2006-004 Security Update 2006-004 is now available and addresses the following issues: AFP Server CVE-ID: CVE-2006-1472 Available for: Mac OS X v10.3.9, Mac OS X Server v10.3.9 Impact: When file sharing is enabled, file and folder items may be disclosed to unauthorized users Description: An issue in the AFP server allows search results to include files and folders for which the user performing the search has no access. This may lead to information disclosure if the names themselves are sensitive information. If the permissions of the items allow it, the contents may also be accessible. This update addresses the issue in Mac OS X v10.3.9 by ensuring that search results only include items for which the user is authorized. For Mac OS X v10.4 systems, the issue was addressed in Mac OS X v10.4.7. AFP Server CVE-ID: CVE-2006-1473 Available for: Mac OS X v10.3.9, Mac OS X Server v10.3.9, Mac OS X v10.4.7, Mac OS X Server v10.4.7 Impact: When file sharing is enabled, authenticated users may cause a crash or arbitrary code execution Description: The AFP server contains an integer overflow that can be triggered by an authenticated user. A malicious user with access to the AFP server may be able to cause a denial of service attack or aribtrary code execution with system privileges. The AFP server is not enabled by default on Mac OS X. This update addresses the issue by performing additional validation. Credit to Dino Dai Zovi of Matasano Security for reporting this issue. AFP Server CVE-ID: CVE-2006-3495 Available for: Mac OS X Server v10.3.9, Mac OS X Server v10.4.7 Impact: When file sharing is enabled, authenticated local users may be able to access files or folders of other users through AFP Description: On Mac OS X Server, the AFP server supports reconnection of file sharing sessions after a network outage. The storage of reconnect keys is world-readable. It may be possible for an authenticated local user to read the reconnect keys, use them to impersonate another user over AFP, and access files or folders with the privileges of the impersonated user. This update addresses the issue by protecting the reconnect keys with appropriate file system permissions. This issue only affects Mac OS X Server. AFP Server CVE-ID: CVE-2006-3496 Available for: Mac OS X v10.3.9, Mac OS X Server v10.3.9, Mac OS X v10.4.7, Mac OS X Server v10.4.7 Impact: When file sharing is enabled, a maliciously-crafted AFP request may cause the AFP server to crash Description: An unchecked error condition exists in the AFP server that may lead to a crash. By carefully crafting an invalid AFP request, an attacker may be able to trigger this condition and cause a denial of service. This update addresses the issue by handling the formerly unchecked error condition. AppKit, ImageIO CVE-ID: CVE-2006-3459, CVE-2006-3461, CVE-2006-3462, CVE-2006-3465 Available for: Mac OS X v10.3.9, Mac OS X Server v10.3.9, Mac OS X v10.4.7, Mac OS X Server v10.4.7 Impact: Viewing a maliciously-crafted TIFF image may lead to an application crash or arbitrary code execution Description: Buffer overflows were discovered in TIFF tag handling (CVE-2006-3459, CVE-2006-3465), the TIFF PixarLog decoder (CVE-2006-3461), and the TIFF NeXT RLE decoder (CVE-2006-3462). By carefully crafting a corrupt TIFF image, an attacker can trigger a buffer overflow which may lead to an application crash or arbitrary code execution. This update addresses the issue by performing additional validation of TIFF images. Systems prior to Mac OS X v10.4 are affected only by the TIFF NeXT RLE decoder issue (CVE-2006-3462). Credit to Tavis Ormandy, Google Security Team for reporting this issue. Note: A fifth issue discovered by Tavis Ormandy, CVE-2006-3460, does not affect Mac OS X. Bluetooth Setup Assistant Available for: Mac OS X v10.4.7, Mac OS X Server v10.4.7 Impact: Passkey length increased for Bluetooth pairing Description: The length of the automatically generated passkey used for pairing has been increased from six characters to eight characters.

By carefully crafting a malicious BOOTP request, a remote attacker may be able to trigger the overflow and cause arbitrary code execution with the privileges of the system. Note that bootpd is not enabled by default in Mac OS X, and must be manually configured in order to be enabled. This update addresses the issue by performing additional bounds checking. dyld CVE-ID: CVE-2006-3499 Available for: Mac OS X v10.3.9, Mac OS X Server v10.3.9, Mac OS X v10.4.7, Mac OS X Server v10.4.7 Impact: Malicious local users may influence dynamic linker output with undesirable consequences Description: Malicious local system users may specify dynamic linker options that cause output to standard error. This output contains informational content and potentially user-specified content. As a result, privileged applications that parse or reuse standard error may be influenced inappropriately. This update addresses the issue by ignoring the problematic dynamic linker options in privileged applications. Credit to Neil Archibald of Suresec LTD for reporting this issue. dyld CVE-ID: CVE-2006-3500 Available for: Mac OS X v10.4.7, Mac OS X Server v10.4.7 Impact: Malicious local users may influence the loading of dynamic libraries in order to gain elevated privileges Description: An improperly handled condition in the dynamic linker may lead to including dangerous paths when searching for libraries to load into privileged applications. As a result, malicious local users may cause the dynamic linker to load and execute arbitrary code with elevated privileges. This update addresses the issue by properly selecting search paths when executing privileged applications. Credit to Neil Archibald of Suresec LTD for reporting this issue. fetchmail CVE-ID: CVE-2005-2335, CVE-2005-3088, CVE-2005-4348, CVE-2006-0321 Available for: Mac OS X v10.3.9, Mac OS X Server v10.3.9, Mac OS X v10.4.7, Mac OS X Server v10.4.7 Impact: Multiple issues in the fetchmail utility may lead to denial of service or arbitrary code execution Description: Several issues in the fetchmail utility were discovered. The most serious issue could lead to arbitrary code execution when fetching mail from a malicious POP3 mail server. All issues are described at the fetchmail website (fetchmail.berlios.de). This update addresses the issues by updating fetchmail to version 6.3.4. In addition, fetchmail is no longer distributed as a privileged utility. gunzip CVE-ID: CVE-2005-0988 Available for: Mac OS X v10.3.9, Mac OS X Server v10.3.9, Mac OS X v10.4.7, Mac OS X Server v10.4.7 Impact: Malicious local users may be able to modify permissions of files owned by another user when the command line tool gunzip is run Description: A race condition may allow a malicious local user to modify the permissions of files owned by another user executing gunzip. This issue is only exploitable when executing gunzip on files in directories that are modifiable by other users. This update addresses the issue by properly handling files while decompressing. gunzip CVE-ID: CVE-2005-1228 Available for: Mac OS X v10.3.9, Mac OS X Server v10.3.9, Mac OS X v10.4.7, Mac OS X Server v10.4.7 Impact: Decompressing maliciously-crafted files with "gunzip -N" may lead to arbitrary file replacement or creation Description: A directory traversal vulnerability is present in the command line utility gunzip when it is used with the non-default "-N" option. By carefully crafting a malicious compressed file and persuading a user to open it with "gunzip - -N", an attacker may replace or create arbitrary files with the privileges of the victim. This update addresses the issue by properly stripping paths from files when decompressing. Image RAW CVE-ID: CVE-2006-0392 Available for: Mac OS X v10.4.7, Mac OS X Server v10.4.7 Impact: Viewing a maliciously-crafted Canon RAW image may lead to an application crash or arbitrary code execution Description: By carefully crafting a corrupt Canon RAW image, an attacker can trigger a buffer overflow which may lead to an application crash or arbitrary code execution.

LaunchServices CVE-ID: CVE-2006-3504 Available for: Mac OS X v10.4.7, Mac OS X Server v10.4.7 Impact: Visiting a malicious web site could cause JavaScript to execute in the local domain Description: Download Validation may erroneously identify certain files containing HTML as "safe". If such a file is downloaded in Safari and Safari's "Open `safe' files after downloading" option is enabled, the HTML document will automatically be opened from a local URI. This would allow any JavaScript code embedded in the document to bypass access restrictions normally imposed on remote content. This update provides additional checks to identify potentially malicious file types so that they are not automatically opened. This issue does not affect systems prior to Mac OS X v10.4. OpenSSH CVE-ID: CVE-2006-0393 Available for: Mac OS X v10.4.7, Mac OS X Server v10.4.7 Impact: When remote login is enabled, remote attackers may cause a denial of service or determine whether an account exists Description: Attempting to log in to an OpenSSH server ("Remote Login") using a nonexistent account causes the authentication process to hang. An attacker can exploit this behavior to detect the existence of a particular account. A large number of such attempts may lead to a denial of service. This update addresses the issue by properly handling attempted logins by nonexistent users. This issue does not affect systems prior to Mac OS X v10.4. Credit to Rob Middleton of the Centenary Institute (Sydney, Australia) for reporting this issue. telnet CVE-ID: CVE-2005-0488 Available for: Mac OS X v10.3.9, Mac OS X Server v10.3.9, Mac OS X v10.4.7, Mac OS X Server v10.4.7 Impact: When the command line tool telnet is used to connect to a malicious TELNET server, environmental variables may be disclosed Description: When connected to a TELNET server, the client may send the contents of arbitrary environment variables to the server if the server requests them. Some environment variables may contain sensitive information that should not be sent over the network. This update addresses the issue by ensuring that only non-sensitive variables and variables that the user has explicitly requested are are shared with the server.
