TITLE:
Adobe Reader / Acrobat AcroPDF ActiveX Control Bugs

SECUNIA ADVISORY ID:
SA23138

VERIFY ADVISORY:
http://secunia.com/advisories/23138/

CRITICAL:
Not critical

IMPACT:
DoS

WHERE:
Local system

SOFTWARE:
Adobe Reader 7.x
http://secunia.com/product/4546/
Adobe Acrobat 7.x
http://secunia.com/product/4594/

DESCRIPTION:
Some bugs have been discovered in Adobe Reader and Adobe Acrobat,
which may cause an included ActiveX control to crash.

The bugs are caused due to errors in the AcroPDF ActiveX control
(AcroPDF.dll) when processing arbitrary arguments passed to the
"setPageMode()", "setLayoutMode()", "setNamedDest()", and
"LoadFile()" methods.

NOTE: Secunia has currently decided to treat these issues as crash
bugs as further internal research and dialogue with the vendor
indicates that no risk of potential remote code execution has been
proven. Currently, only crashes have been confirmed by locally
executing a WSF file (Windows Script File), which is considered an
untrusted file type.

The bugs are confirmed in Adobe Reader 7.0.5 and 7.0.8 for Windows.
They have also been reported in Adobe Reader 7.0.0 through 7.0.8 and
Adobe Acrobat Standard and Professional 7.0.0 through 7.0.8 on the
Windows platform. Prior versions may also be affected.

SOLUTION:
The vendor recommends deleting AcroPDF.dll (this workaround will
prevent PDF documents from opening in Internet Explorer).

The vendor is currently working on an update for version 7.0.8 for
Adobe Reader and Adobe Acrobat.

PROVIDED AND/OR DISCOVERED BY:
Originally reported in the "LoadFile()" method by Michal Bucko
(sapheal), hack.pl.
Other bugs reported by FrSIRT.
