xpdf

Alin Rad Pop (Secunia) discovered a number of vulnerabilities in xpdf, a set
of tools for display and conversion of Portable Document Format (PDF) files.
The Common Vulnerabilities and Exposures project identifies the following
three problems:

• CVE-2007-4352
  Inadequate DCT stream validation allows an attacker to corrupt
  memory and potentially execute arbitrary code by supplying a
  maliciously crafted PDF file.
• CVE-2007-5392
  An integer overflow vulnerability in DCT stream handling could
  allow an attacker to overflow a heap buffer, enabling the execution
  of arbitrary code.
• CVE-2007-5393
  A buffer overflow vulnerability in xpdf’s CCITT image compression
  handlers allows overflow on the heap, allowing an attacker to
  execute arbitrary code by supplying a maliciously crafted
  CCITTFaxDecode filter.

For the stable distribution (etch), these problems have been fixed in
version 3.01-9.1+etch2.

For the unstable distribution (sid), these problems have been fixed in
version 3.02-1.3.

We recommend that you upgrade your xpdf packages.
