DLA 1273-1: simplesamlphp security update

Package : simplesamlphp
Version : 1.9.2-1+deb7u2
CVE ID : CVE-2017-18121 CVE-2017-18122 CVE-2018-6521
Debian Bug : 889286


simplesamlphp, an authentication and federation application has been
found vulnerable to Cross Site Scripting (XSS), signature validation
byepass and using insecure connection charset.

CVE-2017-18121

A Cross Site Scripting (XSS) issue has been found in the
consentAdmin module of SimpleSAMLphp through 1.14.15, allowing an
attacker to manually craft links that a victim can open, executing
arbitrary javascript code.

CVE-2017-18122

A signature-validation bypass issue was discovered in SimpleSAMLphp
through 1.14.16. Service Provider using SAML 1.1 will regard as
valid any unsigned SAML response containing more than one signed
assertion, provided that the signature of at least one of the
assertions is valid. Attributes contained in all the assertions
received will be merged and the entityID of the first assertion
received will be used, allowing an attacker to impersonate any user
of any IdP given an assertion signed by the targeted IdP.

CVE-2018-6521

The sqlauth module in SimpleSAMLphp before 1.15.2 relies on the
MySQL utf8 charset, which truncates queries upon encountering
four-byte characters. There might be a scenario in which this allows
remote attackers to bypass intended access restrictions.

For Debian 7 "Wheezy", these problems have been fixed in version
1.9.2-1+deb7u2.

We recommend that you upgrade your simplesamlphp packages.

https://www.debian.org/security/
February 08, 2018 https://www.debian.org/security/faq
- -------------------------------------------------------------------------

Package : mpv
CVE ID : CVE-2018-6360
Debian Bug : 889892

A regression was detected in the previously issued fix for CVE-2018-6360.
The patch released with DSA 4105-1 broke the feature of invoking mpv with
raw YouTube ids. This update fixes this functionality issue. For
reference, the relevant part of the original advisory text follows.

It was discovered that mpv, a media player, was vulnerable to remote code
execution attacks. An attacker could craft a malicious web page that,
when used as an argument in mpv, could execute arbitrary code in the host
of the mpv user.

For the stable distribution (stretch), this problem has been fixed in
version 0.23.0-2+deb9u2.

We recommend that you upgrade your mpv packages.
