[SECURITY] [DLA 1205-1] simplesamlphp security update

Package : simplesamlphp
Version : 1.9.2-1+deb7u1
CVE ID : CVE-2017-12867 CVE-2017-12868 CVE-2017-12869 CVE-2017-12872
CVE-2017-12873 CVE-2017-12874

The simplesamlphp package in wheezy is vulnerable to multiple attacks
on authentication-related code, leading to unauthorized access and
information disclosure.

CVE-2017-12867

The SimpleSAML_Auth_TimeLimitedToken class allows attackers with
access to a secret token to extend its validity period by manipulating
the prepended time offset.

CVE-2017-12869

The multiauth module allows remote attackers to bypass authentication
context restrictions and use an authentication source defined in
config/authsources.php via vectors related to improper validation of
user input.

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 iattackers 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.

CVE-2017-12873

SimpleSAMLphp might allow attackers to obtain sensitive information,
gain unauthorized access, or have unspecified other impacts by
leveraging incorrect persistent NameID generation when an Identity
Provider (IdP) is misconfigured.

CVE-2017-12874

The InfoCard module for SimpleSAMLphp allows attackers to spoof
XML messages by leveraging an incorrect check of return values in
signature validation utilities.

For Debian 7 "Wheezy", these problems have been fixed in version
1.9.2-1+deb7u1.

We recommend that you upgrade your simplesamlphp packages.
