FreeRDP has a heap-buffer-overflow in drive_process_irp_read

FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to 3.20.1, a heap-buffer-overflow occurs in drive read when a server-controlled read length is used to read file data into an IRP output stream buffer without a hard upper bound, allowing an oversized read to overwrite heap memory. This vulnerability is fixed in 3.20.1.

Dask distributed Vulnerable to Remote Code Execution via Jupyter Proxy and Dashboard

Dask distributed is a distributed task scheduler for Dask. Prior to 2026.1.0, when Jupyter Lab, jupyter-server-proxy, and Dask distributed are all run together, it is possible to craft a URL which will result in code being executed by Jupyter due to a cross-side-scripting (XSS) bug in the Dask dashboard. It is possible for attackers to craft a phishing URL that assumes Jupyter Lab and Dask may be running on localhost and using default ports. If a user clicks on the malicious link it will open an error page in the Dask Dashboard via the Jupyter Lab proxy which will cause code to be executed by the default Jupyter Python kernel. This vulnerability is fixed in 2026.1.0.

FreeRDP has a heap-buffer-overflow in ndr_read_uint8Array

FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to 3.20.1, RDPEAR’s NDR array reader does not perform bounds checking on the on‑wire element count and can write past the heap buffer allocated from hints, causing a heap buffer overflow in ndr_read_uint8Array. This vulnerability is fixed in 3.20.1.

Gradle's failure to disable repositories failing to answer can expose builds to malicious artifacts

Gradle is a build automation tool, and its native-platform tool provides Java bindings for native APIs. When resolving dependencies in versions before 9.3.0, some exceptions were not treated as fatal errors and would not cause a repository to be disabled. If a build encountered one of these exceptions, Gradle would continue to the next repository in the list and potentially resolve dependencies from a different repository. An exception like NoHttpResponseException can indicate transient errors. If the errors persist after a maximum number of retries, Gradle would continue to the next repository. This behavior could allow an attacker to disrupt the service of a repository and leverage another repository to serve malicious artifacts. This attack requires the attacker to have control over a repository after the disrupted repository. Gradle has introduced a change in behavior in Gradle 9.3.0 to stop searching other repositories when encountering these errors.
