Package        : libextractor
Version        : 1:1.3-2+deb8u4
CVE ID         : CVE-2018-20430 CVE-2018-20431
Debian Bug     : 917214 917213

Two security issues were discovered in libextractor, a library for
extracting meta data from files of arbitrary type. An out-of-bounds
read in common/convert.c and a NULL Pointer Dereference in the OLE2
extractor may lead to a denial-of-service (application crash).

For Debian 8 "Jessie", these problems have been fixed in version
1:1.3-2+deb8u4.

We recommend that you upgrade your libextractor packages.
