Recent vulnerabilities in Poppler may result in system crashes or unintended code execution on Ubuntu platforms. It's crucial to apply significant updates.
poppler could be made to crash or run programs if it opened a specially crafted file.

Summary

poppler could be made to crash or run programs if it opened a specially

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

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)
