iChat in Apple Mac OS X 10.5 before 10.5.7 disables SSL for AOL Instant Messenger (AIM) communication in certain circumstances that are inconsistent with the Require SSL setting, which allows remote attackers to obtain sensitive information by sniffing the network.

Stack-based buffer overflow in Apple Mac OS X 10.5 before 10.5.7 allows local users to gain privileges or cause a denial of service (application crash) by attempting to mount a crafted sparse disk image.

Apple Mac OS X 10.4.11 and 10.5 before 10.5.7 allows local users to gain privileges or cause a denial of service (application crash) by attempting to mount a crafted sparse disk image that triggers memory corruption.

CoreGraphics in Apple Mac OS X 10.4.11 and 10.5 before 10.5.7, iPhone OS 1.0 through 2.2.1, and iPhone OS for iPod touch 1.1 through 2.2.1 allows remote attackers to execute arbitrary code or cause a denial of service (application crash) via a crafted PDF file that triggers memory corruption.

CFNetwork in Apple Mac OS X 10.5 before 10.5.7 does not properly parse noncompliant Set-Cookie headers, which allows remote attackers to obtain sensitive information by sniffing the network for "secure cookies" that are sent over unencrypted HTTP connections.

Integer underflow in QuickDraw Manager in Apple Mac OS X 10.4.11 and 10.5 before 10.5.7, and Apple QuickTime before 7.6.2, allows remote attackers to execute arbitrary code or cause a denial of service (application crash) via a PICT image with a crafted 0x77 Poly tag and a crafted length field, which triggers a heap-based buffer overflow.

Array index error in the xnu (Mach) kernel in Apple Mac OS X 10.5 before 10.5.7 allows local users to gain privileges or cause a denial of service (system shutdown) via unspecified vectors related to workqueues.

The asn1_decode_generaltime function in lib/krb5/asn.1/asn1_decode.c in the ASN.1 GeneralizedTime decoder in MIT Kerberos 5 (aka krb5) before 1.6.4 allows remote attackers to cause a denial of service (daemon crash) or possibly execute arbitrary code via vectors involving an invalid DER encoding that triggers a free of an uninitialized pointer.

Race condition in the HFS vfs sysctl interface in XNU 1228.8.20 and earlier on Apple Mac OS X 10.5.6 and earlier allows local users to cause a denial of service (kernel memory corruption) by simultaneously executing the same HFS_SET_PKG_EXTENSIONS code path in multiple threads, which is problematic because of lack of mutex locking for an unspecified global variable.

Multiple memory leaks in XNU 1228.3.13 and earlier on Apple Mac OS X 10.5.6 and earlier allow local users to cause a denial of service (kernel memory consumption) via a crafted (1) SYS_add_profil or (2) SYS___mac_getfsstat system call.

Heap-based buffer overflow in the AppleTalk networking stack in XNU 1228.3.13 and earlier on Apple Mac OS X 10.5.6 and earlier allows remote attackers to cause a denial of service (system crash) via a ZIP NOTIFY (aka ZIPOP_NOTIFY) packet that overwrites a certain ifPort structure member.

XNU 1228.9.59 and earlier on Apple Mac OS X 10.5.6 and earlier does not properly restrict interaction between user space and the HFS IOCTL handler, which allows local users to overwrite kernel memory and gain privileges by attaching an HFS+ disk image and performing certain steps involving HFS_GET_BOOT_INFO fcntl calls.

The PNG reference library (aka libpng) before 1.0.43, and 1.2.x before 1.2.35, as used in pngcrush and other applications, allows context-dependent attackers to cause a denial of service (application crash) or possibly execute arbitrary code via a crafted PNG file that triggers a free of an uninitialized pointer in (1) the png_read_png function, (2) pCAL chunk handling, or (3) setup of 16-bit gamma tables.

Unspecified vulnerability in Apple QuickTime before 7.6 allows remote attackers to cause a denial of service (application termination) and possibly execute arbitrary code via a crafted H.263 encoded movie file that triggers memory corruption.

Buffer overflow in Apple QuickTime before 7.6 allows remote attackers to cause a denial of service (application termination) and possibly execute arbitrary code via a crafted MP3 audio file.

Heap-based buffer overflow in Apple QuickTime before 7.6 allows remote attackers to cause a denial of service (application termination) and execute arbitrary code via an AVI movie file with an invalid nBlockAlign value in the _WAVEFORMATEX structure.

Heap-based buffer overflow in Apple QuickTime before 7.6 allows remote attackers to cause a denial of service (application termination) and possibly execute arbitrary code via a QTVR movie file with crafted THKD atoms.

Heap-based buffer overflow in Apple QuickTime before 7.6 allows remote attackers to cause a denial of service (application termination) and possibly execute arbitrary code via a crafted RTSP URL.

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.
