koffice - multiple vulnerabilities

Several vulnerabilities have been discovered in xpdf code that is
embedded in koffice, an integrated office suite for KDE. These flaws
could allow an attacker to execute arbitrary code by inducing the user
to import a specially crafted PDF document. The Common Vulnerabilities and
Exposures project identifies the following problems:

• CVE-2007-4352
  Array index error in the DCTStream::readProgressiveDataUnit method in
  xpdf/Stream.cc in Xpdf 3.02pl1, as used in poppler, teTeX, KDE, KOffice,
  CUPS, and other products, allows remote attackers to trigger memory
  corruption and execute arbitrary code via a crafted PDF file.
• CVE-2007-5392
  Integer overflow in the DCTStream::reset method in xpdf/Stream.cc in
  Xpdf 3.02p11 allows remote attackers to execute arbitrary code via a
  crafted PDF file, resulting in a heap-based buffer overflow.
• CVE-2007-5393
  Heap-based buffer overflow in the CCITTFaxStream::lookChar method in
  xpdf/Stream.cc in Xpdf 3.02p11 allows remote attackers to execute
  arbitrary code via a PDF file that contains a crafted CCITTFaxDecode
  filter.

Updates for the old stable distribution (sarge) will be made available
as soon as possible.

For the stable distribution (etch), these problems have been fixed in version
1:1.6.1-2etch2.

We recommend that you upgrade your koffice package.
