<title>Xpdf, GPdf: Stack overflow in Decrypt::makeFileKey2</title>
|
||
|
|
<synopsis>
|
||
|
|
A stack overflow was discovered in Xpdf, potentially resulting in the
|
||
|
|
execution of arbitrary code. GPdf includes Xpdf code and therefore is
|
||
|
|
vulnerable to the same issue.

iDEFENSE reports that the Decrypt::makeFileKey2 function in Xpdf's
|

Decrypt.cc insufficiently checks boundaries when processing /Encrypt

/Length tags in PDF files.

An attacker could entice an user to open a specially-crafted PDF
|
||
|
|
file which would trigger a stack overflow, potentially resulting in
|
||
|
|
execution of arbitrary code with the rights of the user running Xpdf or
|
||
|
|
GPdf.
