Description

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 documents. If a user or automated system were tricked into opening a 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).

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