Updated mat packages are available for Debian 7 LTS
Package : mat
Version : 0.3.2-1+deb7u1
Debian Bug : 826101
An implementation flaw was discovered in mat, the metadata anonymisation
toolkit. The implementation of PDF support lacks support to anonymize
the metadata in embedded images. As there is no easy fix for this flaw,
it was decided that PDF support will be removed altogether from mat for
the time being.
For Debian 7 "Wheezy", these problems have been fixed in version
0.3.2-1+deb7u1.
We recommend that you upgrade your mat packages.
