reads. This could result in information leakage, denial of service, or
potentially incorrect certificate validation results.

For Debian 7 'Wheezy', these problems have been fixed in version
1.10.5-1+deb7u3.

We recommend that you upgrade your botan1.10 packages.

to automatically clean and format it as much as possible without
introducing additional issues."
