Vulnerability Name:

CCN-11470

Published:2003-03-03
Updated:2003-03-03
Summary:Adobe Acrobat Reader could allow a remote attacker to bypass signature checks, caused by a vulnerability when the Adobe Document Server for Reader Extensions is used to process a PDF file. Adobe Document Server for Reader Extensions allows owners of PDF files to assign certain rights to their PDF files. A remote attacker can submit a modified PDF file to bypass signature checks by spoofing the "Rights" Dictionary and Page Content signatures, which would allow the PDF file to be processed as a "rights-enabled" file. An attacker could use this vulnerability to enable certain features within the Acrobat Reader, such as allowing users to download, digitally sign, distribute, and submit PDF files.
