Description Sune Kloppenborg Jeppesen gentoo-dev 2007-10-22 19:50:06 UTC
Secunia Research has discovered some vulnerabilities in Xpdf, which can
be exploited by malicious people to compromise a user's system.

1) An array indexing error exists within the
"DCTStream::readProgressiveDataUnit()" method in xpdf/ This
can be exploited to corrupt memory via a specially crafted PDF file.

2) An integer overflow error exists within the "DCTStream::reset()"
method in xpdf/ This can be exploited to cause a heap-based
buffer overflow via a specially crafted PDF file.

Successful exploitation of the vulnerabilities may allow execution of
arbitrary code.

3) A boundary error exists within the "CCITTFaxStream::lookChar()"
method in xpdf/ This can be exploited to cause a heap-based
buffer overflow by tricking a user into opening a PDF file containing a
specially crafted "CCITTFaxDecode" filter.

Successful exploitation allows execution of arbitrary code.

The vulnerabilities are confirmed in Xpdf 3.02. Other versions may also
be affected.

Vulnerability Details:

1) The vulnerability is caused by missing checks when indexing the
"dctZigZag" array in xpdf/ at lines 2405, 2429, 2454, 2476 and

2) The vulnerability is present in xpdf/ at line 1967.

3) The vulnerability can be triggered when filling the "codingLine"
array in xpdf/ at lines 1373, 1375, 1379, 1381, 1480 or 1489.
This is triggered when the sum of all black and white codes is smaller
than the "/Columns" parameter in "/DecodeParms" (e.g. "getWhiteCode()"
constantly returns 0 and "getBlackCode()" constantly returns 1).   

Closing comments:

We have assigned these vulnerabilities Secunia advisory SA27260 and the
following CVE identifiers:
1) CVE-2007-4352
2) CVE-2007-5392
3) CVE-2007-5393

Upstream contacted.
Disclosure date: As soon as the vendor releases a patch, or 2007-10-31.

This one is public now. Do we have a list of affected packages?
Comment 7 Robert Buchholz (RETIRED) gentoo-dev 2007-11-07 23:24:22 UTC
From our embedded-copies list:

== XPDF ==
* app-text/poppler
* app-text/tetex
* app-text/cstetex
* app-text/ptex
* app-office/kword
* app-office/koffice
* kde-base/kpdf
* kde-base/kdegraphics

False positives:
* media-libs/libextractor: Since 0.5.12 libextractor is shipping its own PDF support
  and at least in 0.5.15 it is also enabled by default.
* net-print/cups: Uses poppler
* app-text/xpdf: Uses poppler
* gnustep-libs/pdfkit: removed
* gnustep-libs/imagekits: removed
* okular (kpdf in kde 4): Uses poppler

Sorry, I accidently did not remove arches from that bug. I'll leave it up to the assignee to close.
