"Leon Zhao discovered several security vulnerabilities in libextractor,
a universal library and command-line tool to obtain meta-data about
files. NULL pointer Dereferences, heap-based buffer overflows, integer
signedness errors and out-of-bounds read may lead to a
denial of service (application crash) or have other unspecified
impact.

For Debian 7 'Wheezy', these problems have been fixed in version
1:0.6.3-5+deb7u1.

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."
