didiwiki - security update

Alexander Izmailov discovered that didiwiki, a wiki implementation,
failed to correctly validate user-supplied input, thus allowing a
malicious user to access any part of the filesystem.

For the oldstable distribution (wheezy), this problem has been fixed
in version 0.5-11+deb7u1.

For the stable distribution (jessie), this problem has been fixed in
version 0.5-11+deb8u1.

For the testing (stretch) and unstable (sid) distributions, this
problem has been fixed in version 0.5-12.

We recommend that you upgrade your didiwiki packages.
