POP3 service in Avaya Modular Messaging Message Storage Server (MSS) 2.0 SP 4 and earlier allows remote attackers to cause a denial of service (infinite loop) via crafted packets.

The 64 bit ELF support in Linux kernel 2.6 before 2.6.10, on 64-bit architectures, does not properly check for overlapping VMA (virtual memory address) allocations, which allows local users to cause a denial of service (system crash) or execute arbitrary code via a crafted ELF or a.out file.

Race condition in the (1) load_elf_library and (2) binfmt_aout function calls for uselib in Linux kernel 2.4 through 2.429-rc2 and 2.6 through 2.6.10 allows local users to execute arbitrary code by manipulating the VMA descriptor.

Internet Explorer 6.x allows remote attackers to install arbitrary programs via mousedown events that call the Popup.show method and use drag-and-drop actions in a popup window, aka "HijackClick 3" and the "Script in Image Tag File Download Vulnerability."

Internet Explorer 6.0 SP1 and earlier, and possibly other versions, allows remote attackers to cause a denial of service (application crash from "memory corruption") via certain malformed Cascading Style Sheet (CSS) elements that trigger heap-based buffer overflows, as demonstrated using the "<STYLE>@;/*" string, possibly due to a missing comment terminator that may cause an invalid length to trigger a large memory copy operation, aka the "CSS Heap Memory Corruption Vulnerability."

Integer overflow in the TIFFFetchStripThing function in tif_dirread.c for libtiff 3.6.1 allows remote attackers to execute arbitrary code via a TIFF file with the STRIPOFFSETS flag and a large number of strips, which causes a zero byte buffer to be allocated and leads to a heap-based buffer overflow.

Internet Explorer in Windows XP SP2, and other versions including 5.01 and 5.5, allows remote attackers to install arbitrary programs via a web page that uses certain styles and the AnchorClick behavior, popup windows, and drag-and-drop capabilities to drop the program in the local startup folder, as demonstrated by "wottapoop.html".

Linux kernel 2.4.x and 2.6.x for x86 allows local users to cause a denial of service (system crash), possibly via an infinite loop that triggers a signal handler with a certain sequence of fsave and frstor instructions, as originally demonstrated using a "crash.c" program.

Multiple unknown vulnerabilities in Linux kernel 2.4 and 2.6 allow local users to gain privileges or access kernel memory, as found by the Sparse source code checking tool.

mod_digest_apple for Apache 1.3.31 and 1.3.32 on Mac OS X Server does not properly verify the nonce of a client response, which allows remote attackers to replay credentials.
