Joplin version 2.8.8 allows an external attacker to execute arbitrary commands remotely on any client that opens a link in a malicious markdown file, via Joplin. This is possible because the application does not properly validate the schema/protocol of existing links in the markdown file before passing them to the 'shell.openExternal' function.

Ubuntu Security Notice 5647-1 - It was discovered that the framebuffer driver on the Linux kernel did not verify size limits when changing font or screen size, leading to an out-of- bounds write. A local attacker could use this to cause a denial of service or possibly execute arbitrary code. Moshe Kol, Amit Klein and Yossi Gilad discovered that the IP implementation in the Linux kernel did not provide sufficient randomization when calculating port offsets. An attacker could possibly use this to expose sensitive information.

Ubuntu Security Notice 5646-1 - Tobias Stoeckmann discovered that libXi did not properly manage memory when handling X server responses. A remote attacker could use this issue to cause libXi to crash, resulting in a denial of service.

### Impact Improperly formed beacon events (from [MSC3488](https://github.com/matrix-org/matrix-spec-proposals/pull/3488)) can disrupt or impede the matrix-js-sdk from functioning properly, potentially impacting the consumer's ability to process data safely. Note that the matrix-js-sdk can appear to be operating normally but be excluding or corrupting runtime data presented to the consumer. ### Patches This is patched in matrix-js-sdk v19.7.0 ### Workarounds Redacting applicable events, waiting for the sync processor to store data, and restarting the client can often fix it. Alternatively, redacting the applicable events and clearing all storage will fix the further perceived issues. Downgrading to an unaffected version, noting that such a version may be subject to other vulnerabilities, will additionally resolve the issue. ### References N/A - This was a logic error in the SDK. ### For more information If you have any questions or comments about this advisory please email us at [...
