Apple Mac OS X Server

libsecurity in Apple Mac OS X before 10.7.4 accesses uninitialized memory locations during the processing of X.509 certificates, which allows remote attackers to execute arbitrary code or cause a denial of service (application crash) via a crafted certificate.

Apple Filing Protocol (AFP) Server in Apple Mac OS X 10.6.x through 10.6.4 does not properly handle errors, which allows remote attackers to bypass the password requirement for shared-folder access by leveraging knowledge of a valid account name.

A certain pseudo-random number generator (PRNG) algorithm that uses XOR and 2-bit random hops (aka "Algorithm X2"), as used in OpenBSD 2.6 through 3.4, Mac OS X 10 through 10.5.1, FreeBSD 4.4 through 7.0, and DragonFlyBSD 1.0 through 1.10.1, allows remote attackers to guess sensitive values such as IP fragmentation IDs by observing a sequence of previously generated values. NOTE: this issue can be leveraged for attacks such as injection into TCP packets and OS fingerprinting.

Multiple format string vulnerabilities in AppleScript in Apple Mac OS X before 10.6.7 allow context-dependent attackers to execute arbitrary code or cause a denial of service (application crash) via format string specifiers in a (1) display dialog or (2) display alert command in a dialog in an AppleScript Studio application.

A certain pseudo-random number generator (PRNG) algorithm that uses ADD with 0 random hops (aka "Algorithm A0"), as used in OpenBSD 3.5 through 4.2 and NetBSD 1.6.2 through 4.0, allows remote attackers to guess sensitive values such as (1) DNS transaction IDs or (2) IP fragmentation IDs by observing a sequence of previously generated values. NOTE: this issue can be leveraged for attacks such as DNS cache poisoning, injection into TCP packets, and OS fingerprinting.

A certain pseudo-random number generator (PRNG) algorithm that uses XOR and 3-bit random hops (aka "Algorithm X3"), as used in OpenBSD 2.8 through 4.2, allows remote attackers to guess sensitive values such as DNS transaction IDs by observing a sequence of previously generated values. NOTE: this issue can be leveraged for attacks such as DNS cache poisoning against OpenBSD's modification of BIND.

The SSL implementation in Apple Safari before 5.1.1 on Mac OS X before 10.7 accesses uninitialized memory during the processing of X.509 certificates, which allows remote web servers to execute arbitrary code via a crafted certificate.

Multiple use-after-free vulnerabilities in libxml2 2.5.10, 2.6.16, 2.6.26, 2.6.27, and 2.6.32, and libxml 1.8.17, allow context-dependent attackers to cause a denial of service (application crash) via crafted (1) Notation or (2) Enumeration attribute types in an XML file, as demonstrated by the Codenomicon XML fuzzing framework.

Open Directory in Apple Mac OS X 10.7 before 10.7.2 does not require a user to provide the current password before changing this password, which allows remote attackers to bypass intended password-change restrictions by leveraging an unattended workstation.

Dovecot in Apple Mac OS X 10.6 before 10.6.3, when Kerberos is enabled, does not properly enforce the service access control list (SACL) for sending and receiving e-mail, which allows remote authenticated users to bypass intended access restrictions via unspecified vectors.

Multiple heap-based buffer overflows in Mac OS X 10.4.6 and earlier allow remote attackers to cause a denial of service and possibly execute arbitrary code via the (1) PredictorVSetField function for TIFF or (2) CFAllocatorAllocate function for GIF, as used in applications that use ImageIO or AppKit. NOTE: the BMP vector has been re-assigned to CVE-2006-2238 because it affects a separate product family.

Stack-based buffer overflow in Safari in Mac OS X 10.4.5 and earlier, and 10.3.9 and earlier, allows remote attackers to execute arbitrary code via unspecified vectors involving a web page with crafted JavaScript, a different vulnerability than CVE-2005-4504.

Foundation in Apple Mac OS X 10.4.11 might allow context-dependent attackers to execute arbitrary code via a malformed selector name to the NSSelectorFromString API, which causes an "unexpected selector" to be used.

Heap-based buffer overflow in LibSystem in Mac OS X 10.4 through 10.4.5 allows context-dependent attackers to execute arbitrary code by causing an application that uses LibSystem to request a large amount of memory.

Perl-Compatible Regular Expression (PCRE) library before 7.3 backtracks too far when matching certain input bytes against some regex patterns in non-UTF-8 mode, which allows context-dependent attackers to obtain sensitive information or cause a denial of service (crash), as demonstrated by the "\X?\d" and "\P{L}?\d" patterns.

servermgrd in Apple Mac OS X before 10.6.8 allows remote attackers to read arbitrary files, and possibly send HTTP requests to intranet servers or cause a denial of service (CPU and memory consumption), via an XML-RPC request containing an entity declaration in conjunction with an entity reference, related to an XML External Entity (aka XXE) issue.

The OpenSSL::OCSP module for Ruby in Apple Mac OS X 10.5 before 10.5.7 misinterprets an unspecified invalid response as a successful OCSP certificate validation, which might allow remote attackers to spoof certificate authentication via a revoked certificate.

The Application Firewall in Apple Mac OS X 10.5.8 drops unspecified firewall rules after a reboot, which might allow remote attackers to bypass intended access restrictions via packet data, related to a "timing issue."

freshclam in ClamAV in Apple Mac OS X 10.5.8 with Security Update 2009-005 has an incorrect launchd.plist ProgramArguments key and consequently does not run, which might allow remote attackers to introduce viruses into the system.

libsecurity in Apple Mac OS X before 10.7.4 does not properly restrict the length of RSA keys within X.509 certificates, which makes it easier for remote attackers to defeat cryptographic protection mechanisms by conducting a spoofing or network-sniffing attack during communication with a site that uses a short key.

Mac OS X before 10.2.5 allows guest users to modify the permissions of the DropBox folder and read unauthorized files.

libsecurity in Apple Mac OS X 10.5.8 and 10.6.4 does not properly perform comparisons to domain-name strings in X.509 certificates, which allows man-in-the-middle attackers to spoof SSL servers via a certificate associated with a similar domain name, as demonstrated by use of a www.example.con certificate to spoof www.example.com.

Login Window in Apple Mac OS X 10.4.11 does not clear the current password when a user makes a password-change attempt that is denied by policy, which allows opportunistic, physically proximate attackers to bypass authentication and change this user's password by later entering an acceptable new password on the same login screen.

Race condition in Login Window in Apple Mac OS X 10.6.x before 10.6.2, when at least one account has a blank password, allows attackers to bypass password authentication and obtain login access to an arbitrary account via unspecified vectors.

Samba 3.4 before 3.4.2, 3.3 before 3.3.8, 3.2 before 3.2.15, and 3.0.12 through 3.0.36, as used in the SMB subsystem in Apple Mac OS X 10.5.8 when Windows File Sharing is enabled, Fedora 11, and other operating systems, does not properly handle errors in resolving pathnames, which allows remote authenticated users to bypass intended sharing restrictions, and read, create, or modify files, in certain circumstances involving user accounts that lack home directories.

Directory traversal vulnerability in AFP Server in Apple Mac OS X 10.5.8 and 10.6.x before 10.6.5 allows remote authenticated users to execute arbitrary code by creating files that are outside the bounds of a share.

Cross-site request forgery (CSRF) vulnerability in the web interface in CUPS before 1.4.4, as used on Apple Mac OS X 10.5.8, Mac OS X 10.6 before 10.6.4, and other platforms, allows remote attackers to hijack the authentication of administrators for requests that change settings.
