Adobe Acrobat Reader uudecode filename buffer overflow

adobe-acrobat-uudecode-bo (16972) The risk level is classified as HighHigh Risk

Description:

Adobe Acrobat Reader is a program used for reading PDF files. Acrobat Reader versions 5.05 and 5.06 and possibly other versions running on Unix and Linux platforms are vulnerable to a buffer overflow in the uudecode feature, caused by improper bounds checking of filenames. By creating a specially-crafted PDF file, a remote attacker could overflow a buffer and execute arbitrary code on the system with user privileges, once the file is opened. A remote attacker could exploit this vulnerability by sending the malicious file to a victim in an email.
