Multiple vulnerabilites were discovered in privoxy, a privacy enhancing HTTP proxy, like memory leaks, dereference of a NULL pointer, et al.
For Debian 9 stretch, these problems have been fixed in version 3.0.26-3+deb9u1.
We recommend that you upgrade your privoxy packages.
For the detailed security status of privoxy please refer to its security tracker page at:
