Hello All,

In my previous post, I shamefully confused two root keys (WMRMECC256
and ECC256MSBCertRootIssuer) while decribing the issue pertaining to
one of them.

The key exploited in the attack is called ECC256MSBCertRootIssuer Key
(not the WMRMECC256) and is identified by the following public
component:

86 4D 61 CF F2 25 6E 42 2C 56 8B 3C 28 00 1C FB
3E 15 27 65 85 84 BA 05 21 B7 9B 18 28 D9 36 DE

It was discovered that Libcroco was incorrectly accessing data structures
when reading bytes from memory, which could cause a heap buffer overflow.
An attacker could possibly use this issue to cause a denial of service.
This issue only affected Ubuntu 14.04 LTS. (CVE-2017-7960)

It was discovered that Libcroco was incorrectly handling invalid UTF-8
values when processing CSS files. An attacker could possibly use this
issue to cause a denial of service. (CVE-2017-8834, CVE-2017-8871)

It was discovered that Libcroco was incorrectly implementing recursion in
one of its parsing functions, which could cause an infinite recursion
loop and a stack overflow due to stack consumption. An attacker could
possibly use this issue to cause a denial of service. (CVE-2020-12825)

Hello All,

There is an architectural / design issue of PlayReady, which can be
successfully exploited to gain access to license server by arbitrary
clients. The problem has its origin in flat certificate namespace /
reliance on a single root key in PlayReady along no auth at license
server end by default (deemed as no bug by Microsoft).

PlayReady client certificates encountered in Windows 10 / 11 and
CANAL+ STB device environments share a…
