It was discovered that there was a denial of service vulnerability in libpdfbox-java, a PDF library for Java.
A malicious PDF file could have triggered an extremely long running computation when parsing the page tree.
For Debian 8 ‘Jessie’, this issue has been fixed in libpdfbox-java version 1:1.8.7+dfsg-1+deb8u2.
We recommend that you upgrade your libpdfbox-java packages.
NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
