Title
Wagtail: Improper permission handling when comparing revisions
Summary
Wagtail is an open source content management system built on Django. Prior to 7.0.7, 7.3.2, and 7.4, a CMS user without the ability to edit a page could access revisions of the page through the revision compare view if they knew the primary key of two revisions. This could potentially result in disclosure of sensitive information. This vulnerability is fixed in 7.0.7, 7.3.2, and 7.4.

Title
GPU DDK - Insufficient permission check in PhysmemWrapExtMem() when write attribute support enabled
Summary
Software installed and run as a non-privileged user may conduct improper GPU system calls to gain write permission to read-only wrapped user-mode memory.
This is caused by improper handling of the memory protections for the user-mode wrapped memory resource.

Summary
In Modem, there is a possible escalation of privilege due to a permissions bypass. This could lead to local escalation of privilege if a malicious actor has already obtained the System privilege. User interaction is not needed for exploitation. Patch ID: MOLY01716533; Issue ID: MSV-6309.

Mitigation MIT-46
Architecture and Design
Strategy: Separation of Privilege
- Compartmentalize the system to have "safe" areas where trust boundaries can be unambiguously drawn. Do not allow sensitive data to go outside of the trust boundary and always be careful when interfacing with a compartment outside of the safe area.
- Ensure that appropriate compartmentalization is built into the system design, and the compartmentalization allows for and reinforces privilege separation functionality. Architects and designers should rely on the principle of least privilege to decide the appropriate time to use privileges and the time to drop privileges.
Mitigation
Implementation
Always check to see if you have successfully accessed a resource or system functionality, and use proper error handling if it is unsuccessful. Do this even when you are operating in a highly privileged mode, because errors or environmental conditions might still cause a failure. For example, environments with highly granular permissions/privilege models, such as Windows or Linux capabilities, can cause unexpected failures.
