CVE-2017-12872 / CVE-2017-12868

     The (1) Htpasswd authentication source in the authcrypt module and (2)
     SimpleSAML_Session class in SimpleSAMLphp 1.14.11 and earlier allow
     remote attackers to conduct timing side-channel attacks by leveraging
     use of the standard comparison operator to compare secret material
     against user input.

     CVE-2017-12868 was a about an improper fix of CVE-2017-12872 in the
     initial patch released by upstream. We have used the correct patch.


For Debian 8 "Jessie", these problems have been fixed in version
1.13.1-2+deb8u2.

We recommend that you upgrade your simplesamlphp packages.
