Managed Client in Apple Mac OS X before 10.5.6 sometimes misidentifies a system when installing per-host configuration settings, which allows context-dependent attackers to have an unspecified impact by leveraging unintended settings, as demonstrated by the screen saver lock setting.

Apple Type Services (ATS) in Apple Mac OS X 10.5 before 10.5.6 allows remote attackers to cause a denial of service (infinite loop) via a crafted embedded font in a PDF file.

Incomplete blacklist vulnerability in the Quarantine feature in CoreTypes in Apple Mac OS X 10.5 before 10.5.6 allows user-assisted remote attackers to execute arbitrary code via an executable file with the content type indicating no application association for the file, which does not trigger a "potentially unsafe" warning message.

UDF in Apple Mac OS X before 10.5.6 allows user-assisted attackers to cause a denial of service (system crash) via a malformed UDF volume in a crafted ISO file.

natd in network_cmds in Apple Mac OS X before 10.5.6, when Internet Sharing is enabled, allows remote attackers to cause a denial of service (infinite loop) via a crafted TCP packet.

The strptime API in Libsystem in Apple Mac OS X before 10.5.6 allows context-dependent attackers to cause a denial of service (memory corruption and application crash) or execute arbitrary code via a crafted date string, related to improper memory allocation.

Integer overflow in the inet_net_pton API in Libsystem in Apple Mac OS X before 10.5.6 allows context-dependent attackers to execute arbitrary code or cause a denial of service (application crash) via unspecified vectors. NOTE: this may be related to the WLB-2008080064 advisory published by SecurityReason on 20080822; however, as of 20081216, there are insufficient details to be sure.

The kernel in Apple Mac OS X before 10.5.6 allows local users to cause a denial of service (infinite loop and system halt) by running an application that is dynamically linked to libraries on an NFS server, related to occurrence of an exception in this application.

Multiple integer overflows in the kernel in Apple Mac OS X before 10.5.6 on Intel platforms allow local users to gain privileges via a crafted call to (1) i386_set_ldt or (2) i386_get_ldt.

Integer signedness error in BOM in Apple Mac OS X before 10.5.6 allows remote attackers to execute arbitrary code via the headers in a crafted CPIO archive, leading to a stack-based buffer overflow.

cupsd in CUPS 1.3.9 and earlier allows local users, and possibly remote attackers, to cause a denial of service (daemon crash) by adding a large number of RSS Subscriptions, which triggers a NULL pointer dereference. NOTE: this issue can be triggered remotely by leveraging CVE-2008-5184.

Heap-based buffer overflow in the xmlParseAttValueComplex function in parser.c in libxml2 before 2.7.0 allows context-dependent attackers to cause a denial of service (crash) or execute arbitrary code via a long XML entity name.

Apple QuickTime before 7.5.5 allows remote attackers to cause a denial of service (application crash) via a crafted PICT image that triggers an out-of-bounds read.

Heap-based buffer overflow in Apple QuickTime before 7.5.5 allows remote attackers to execute arbitrary code or cause a denial of service (application crash) via a QuickTime Virtual Reality (QTVR) movie file with crafted panorama atoms.

Cross-site scripting (XSS) vulnerability in proxy_ftp.c in the mod_proxy_ftp module in Apache 2.0.63 and earlier, and mod_proxy_ftp.c in the mod_proxy_ftp module in Apache 2.2.9 and earlier 2.2 versions, allows remote attackers to inject arbitrary web script or HTML via a wildcard in the last directory component in the pathname in an FTP URI.

Apple Mac OS X does not properly verify the authenticity of updates, which allows man-in-the-middle attackers to execute arbitrary code via a Trojan horse update, as demonstrated by evilgrade and DNS cache poisoning.

Incomplete blacklist vulnerability in CoreTypes in Apple Mac OS X before 10.5.4 allows user-assisted remote attackers to execute arbitrary code via a (1) .xht or (2) .xhtm file, which does not trigger a "potentially unsafe" warning message in (a) the Download Validation feature in Mac OS X 10.4 or (b) the Quarantine feature in Mac OS X 10.5.

Format string vulnerability in c++filt in Apple Mac OS X 10.5 before 10.5.4 allows user-assisted attackers to execute arbitrary code or cause a denial of service (application crash) via a crafted string in (1) C++ or (2) Java source code.

Launch Services in Apple Mac OS X before 10.5, when Open Safe Files is enabled, allows remote attackers to execute arbitrary code via a symlink attack, probably related to a race condition and automatic execution of a downloaded file.

Apple Mac OS X before 10.5 uses weak permissions for the User Template directory, which allows local users to gain privileges by inserting a Trojan horse file into this directory.
