Debian DLA-1616-1 : libextractor security update

medium Nessus Plugin ID 119876

Language:

Synopsis

The remote Debian host is missing a security update.

Description

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.

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.

Solution

Upgrade the affected packages.
