Chris Williams discovered a flaw in the handling of mounts for
persistent directories in Flatpak, an application deployment framework
for desktop apps. A malicious or compromised Flatpak app using
persistent directories could take advantage of this flaw to access files
outside of the sandbox.

Details can be found in the upstream advisory at

Multiple vulnerabilities have been discovered in Adobe products, the most severe of which could allow for arbitrary code execution.

Adobe is a software that is used for creating and publishing a wide variety of contents including graphics, photography, illustration, animation, multimedia, motion pictures and print.

Successful exploitation of the most severe of these vulnerabilities could allow for arbitrary code execution in the context of the logged on user. Depending on the privileges associated with the user, an attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. Users whose accounts are configured to have fewer user rights on the system could be less impacted than those who operate with administrative user rights

Multiple vulnerabilities have been discovered in Ivanti products, the most severe of which could allow for remote code execution.

Ivanti Avalanche is a mobile device management system.
Ivanti Neurons for ITSM is an IT Service Management Software.
Ivanti Virtual Traffic Manager is a software-based application delivery controller.

Successful exploitation could allow for remote code execution in the context of the system. Depending on the privileges associated with the system, an attacker could then install programs; view, change, or delete data.

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

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…
