"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.

NOTE: Tenable Network Security has extracted the preceding description
block directly from the DLA security advisory. Tenable has attempted
to automatically clean and format it as much as possible without
introducing additional issues."
