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.
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.
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.
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.
Vidalia bundle before 0.1.2.18, when running on Windows and Mac OS X, installs Privoxy with a configuration file (config.txt or config) that contains insecure (1) enable-remote-toggle and (2) enable-edit-actions settings, which allows remote attackers to bypass intended access restrictions and modify configuration.
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.
Format string vulnerability in Wireshark 0.99.8 through 1.0.5 on non-Windows platforms allows local users to cause a denial of service (application crash) via format string specifiers in the HOME environment variable.
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.
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.
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.
