The "faster LJPEG decoder" in libraw 0.13.x, 0.14.x, and 0.15.x before 0.15.4 allows context-dependent attackers to cause a denial of service (NULL pointer dereference) via a crafted photo file.

This update hardens dcraw against corrupt input files which might trigger a division by zero, an infinite loop, or a NULL pointer dereference otherwise.

Note that Tenable Network Security has extracted the preceding description block directly from the Fedora security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Updated libraw packages fix security vulnerabilities :

It was discovered that LibRaw incorrectly handled photo files. If a user or automated system were tricked into processing a specially crafted photo file, applications linked against LibRaw could be made to crash, resulting in a denial of service (CVE-2013-1438, CVE-2013-1439).

It was discovered that libKDcraw incorrectly handled photo files. If a user or automated system were tricked into processing a specially crafted photo file, applications linked against libKDcraw could be made to crash, resulting in a denial of service. (CVE-2013-1438, CVE-2013-1439).

The remote host is affected by the vulnerability described in GLSA-201309-09 (LibRaw, libkdcraw: Multiple vulnerabilities)

    Multiple vulnerabilities have been discovered in LibRaw and libkdcraw.
      Please review the CVE identifiers referenced below for details.
  Impact :

    A remote attacker could entice a user to open a specially crafted file,       possibly resulting in arbitrary code execution or Denial of Service.
  Workaround :

    There is no known workaround at this time.

Raphael Geissert reported two denial of service flaws in LibRaw [1] :

CVE-2013-1438 :

Specially crafted photo files may trigger a division by zero, an infinite loop, or a NULL pointer dereference in libraw leading to denial of service in applications using the library. These vulnerabilities appear to originate in dcraw and as such any program or library based on it is affected. To name a few confirmed applications: dcraw, ufraw. Other affected software: shotwell, darktable, and libkdcraw (Qt-style interface to libraw, using embedded copy) which is used by digikam.

Google Picasa apparently uses dcraw/ufraw so it might be affected.
dcraw's homepage has a list of applications that possibly still use it: http://cybercom.net/~dcoffin/dcraw/

Affected versions of libraw: confirmed: 0.8-0.15.3; but it is likely that all versions are affected.

Fixed in: libraw 0.15.4

CVE-2013-1439 :

Specially crafted photo files may trigger a series of conditions in which a NULL pointer is dereferenced leading to denial of service in applications using the library. These three vulnerabilities are in/related to the 'faster LJPEG decoder', which upstream states was introduced in LibRaw 0.13 and support for which is going to be dropped in 0.16.

Affected versions of libraw: 0.13.x-0.15.x
