" <http://www.adobe.com/products/acrobatstd/main.html> Acrobat is the
Adobe family of PDF (Portable Document Format) file editors and viewers(
<http://en.wikipedia.org/wiki/Adobe_Reader> wiki)."
Exploiting flaws in XML parsing of Adobe Acrobat and Adobe Reader allows
remote attacker to discover the existence of local files on a vulnerable
system.
DETAILS
Vulnerable Systems:
* Adobe Reader 7.0, 7.0.1.
* Adobe Acrobat 7.0, 7.0.1
Immune Systems:
* Adobe Reader 7.0.2 ( <http://www.adobe.com/support/downloads/> here)
* Adobe Acrobat 7.0.2 ( <http://www.adobe.com/support/downloads/> here)
A vulnerability within Adobe Reader and Adobe Acrobat has been identified.
Under certain circumstances, using XML scripts it is possible to discover
the existence of local files.
The vulnerability is within the Adobe Reader control. If an XML script is
embedded in JavaScript, it is possible to discover the existence of local
files. An attacker could then use the information gathered for malicious
purposes.
However the impact is minimized due to the fact that the existence of
local files can only be discovered if the complete filenames and paths are
known in advance by the attacker.
