=========================================================================
A security issue affects these releases of Ubuntu and its derivatives:

crafted file.

Software Description:
- poppler: PDF rendering library

Details:

It was discovered that the poppler pdfseparate tool incorrectly handled
certain filenames. A local attacker could use this issue to cause the tool
to crash, resulting in a denial of service, or possibly execute arbitrary
code. This issue only applied to Ubuntu 12.04 LTS. (CVE-2013-4473,
CVE-2013-4474)

It was discovered that poppler incorrectly parsed certain malformed PDF

crafted PDF file, an attacker could cause a denial of service or possibly
execute arbitrary code with privileges of the user invoking the program.
(CVE-2015-8868)
