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.

The control for Adobe Reader 5.0.9 and 5.0.10 on Linux, Solaris, HP-UX, and AIX creates temporary files with the permissions as specified in a user's umask, which could allow local users to read PDF documents of that user if the umask allows it.

Stack-based buffer overflow in the UnixAppOpenFilePerform function in Adobe Reader 5.0.9 and 5.0.10 for Unix allows remote attackers to execute arbitrary code via a PDF document with a long /Filespec tag.

The Acrobat web control in Adobe Acrobat and Acrobat Reader 7.0 and earlier, when used with Internet Explorer, allows remote attackers to determine the existence of arbitrary files via the LoadFile ActiveX method.

Buffer overflow in the mailListIsPdf function in Adobe Acrobat Reader 5.09 for Unix allows remote attackers to execute arbitrary code via an e-mail message with a crafted PDF attachment.

Buffer overflow in the ActiveX component (pdf.ocx) for Adobe Acrobat 5.0.5 and Acrobat Reader, and possibly other versions, allows remote attackers to execute arbitrary code via a URI for a PDF file with a null terminator (%00) followed by a long string.

The uudecoding feature in Adobe Acrobat Reader 5.0.5 and 5.0.6 for Unix and Linux, and possibly other versions including those before 5.0.9, allows remote attackers to execute arbitrary code via shell metacharacters ("`" or backtick) in the filename of the PDF file that is provided to the uudecode command.

Buffer overflow in the uudecoding feature for Adobe Acrobat Reader 5.0.5 and 5.0.6 for Unix and Linux, and possibly other versions including those before 5.0.9, allows remote attackers to execute arbitrary code via a long filename for the PDF file that is provided to the uudecode command.

Various PDF viewers including (1) Adobe Acrobat 5.06 and (2) Xpdf 1.01 allow remote attackers to execute arbitrary commands via shell metacharacters in an embedded hyperlink.

Adobe Acrobat 5 does not properly validate JavaScript in PDF files, which allows remote attackers to write arbitrary files into the Plug-ins folder that spread to other PDF documents, as demonstrated by the W32.Yourde virus.
