Title
Libsoup: null pointer dereference in libsoup may lead to denial of service
Summary
A denial-of-service vulnerability has been identified in the libsoup HTTP client library. This flaw can be triggered when a libsoup client receives a 401 (Unauthorized) HTTP response containing a specifically crafted domain parameter within the WWW-Authenticate header. Processing this malformed header can lead to a crash of the client application using libsoup. An attacker could exploit this by setting up a malicious HTTP server. If a user's application using the vulnerable libsoup library connects to this malicious server, it could result in a denial-of-service. Successful exploitation requires tricking a user's client application into connecting to the attacker's malicious server.

Title
Gnome-remote-desktop: freerdp: unauthenticated rdp packet causes segfault in freerdp leading to denial of service
Summary
A flaw was found in the FreeRDP used by Anaconda's remote install feature, where a crafted RDP packet could trigger a segmentation fault. This issue causes the service to crash and remain defunct, resulting in a denial of service. It occurs pre-boot and is likely due to a NULL pointer dereference. Rebooting is required to recover the system.

CVE-2025-45525 (GCVE-0-2025-45525)
Vulnerability from cvelistv5 – Published: 2025-06-17 00:00 – Updated: 2025-08-26 18:51 Disputed
VLAI
Summary
A NULL pointer dereference vulnerability has been identified in the JavaScript library microlight version 0.0.7, a lightweight syntax highlighting library. When processing elements with non-standard CSS color values, the library fails to validate the result of a regular expression match before accessing its properties, leading to an uncaught TypeError and potential application crash. NOTE: this is disputed by multiple parties because there is no common scenario in which an adversary can insert those non-standard values.

Mitigation ID: MIT-56
Phase: Implementation
Description:
- For any pointers that could have been modified or provided from a function that can return NULL, check the pointer for NULL before use. When working with a multithreaded or otherwise asynchronous environment, ensure that proper locking APIs are used to lock before the check, and unlock when it has finished [REF-1484].
Mitigation
Phase: Requirements
Description:
- Select a programming language that is not susceptible to these issues.
Mitigation
Phase: Implementation
Description:
- Check the results of all functions that return a value and verify that the value is non-null before acting upon it.
Mitigation
Phase: Architecture and Design
Description:
- Identify all variables and data stores that receive information from external sources, and apply input validation to make sure that they are only initialized to expected values.
Mitigation
Phase: Implementation
Description:
- Explicitly initialize all variables and other data stores, either during declaration or just before the first usage.
