Adobe Acrobat Reader Plugin before 8.0.0, and possibly the plugin distributed with Adobe Reader 7.x before 7.1.4, 8.x before 8.1.7, and 9.x before 9.2, when used with Internet Explorer, Google Chrome, or Opera, allows remote attackers to cause a denial of service (memory consumption) via a long sequence of # (hash) characters appended to a PDF URL, related to a "cross-site scripting issue."

Adobe Reader and Acrobat 7.0.8 and earlier allows user-assisted remote attackers to execute code via a crafted PDF file that triggers memory corruption and overwrites a subroutine pointer during rendering.

Multiple Adobe products, including (1) Photoshop CS2, (2) Illustrator CS2, and (3) Adobe Help Center, install a large number of .EXE and .DLL files with write-access permission for the Everyone group, which allows local users to gain privileges via Trojan horse programs.

Buffer overflow in a "core application plug-in" for Adobe Reader 5.1 through 7.0.2 and Acrobat 5.0 through 7.0.2 allows attackers to cause a denial of service (crash) and possibly execute arbitrary code via unknown vectors.
