This update had been scheduled before the end of security support for the oldstable distribution (squeeze), hence an exception has been made and was released through the security archive. However, no further updates should be expected.

For the oldstable distribution (squeeze), these problems have been fixed in version 1.15.11.

For the stable distribution (wheezy), these problems have been fixed in version 1.16.15.

For the testing distribution (jessie), these problems will be fixed soon.

For the unstable distribution (sid), these problems have been fixed in version 1.17.10.

We recommend that you upgrade your dpkg packages.");
