Ubuntu Security Notice 6300-1 - William Zhao discovered that the Traffic Control subsystem in the Linux kernel did not properly handle network packet retransmission in certain situations. A local attacker could use this to cause a denial of service. It was discovered that the NTFS file system implementation in the Linux kernel did not properly check buffer indexes in certain situations, leading to an out-of-bounds read vulnerability. A local attacker could possibly use this to expose sensitive information.

Flarum is an open source forum software. Flarum is affected by a vulnerability that allows an attacker to conduct a Blind Server-Side Request Forgery (SSRF) attack or disclose any file on the server, even with a basic user account on any Flarum forum. By uploading a file containing a URL and spoofing the MIME type, an attacker can manipulate the application to execute unintended actions. The vulnerability is due to the behavior of the `intervention/image` package, which attempts to interpret the supplied file contents as a URL, which then fetches its contents. This allows an attacker to exploit the vulnerability to perform SSRF attacks, disclose local file contents, or conduct a blind oracle attack. This has been patched in Flarum version 1.8.0. Users are advised to upgrade. Users unable to upgrade may disable PHP's `allow_url_fopen` which will prevent the fetching of external files via URLs as a temporary workaround for the SSRF aspect of the vulnerability.

Ubuntu Security Notice 6288-1 - Multiple security issues were discovered in MySQL and this update includes new upstream MySQL versions to fix these issues. MySQL has been updated to 8.0.34 in Ubuntu 20.04 LTS, Ubuntu 22.04 LTS, and Ubuntu 23.04. In addition to security fixes, the updated packages contain bug fixes, new features, and possibly incompatible changes.

Versions of `ed25519-dalek` prior to v2.0 model private and public keys as separate types which can be assembled into a `Keypair`, and also provide APIs for serializing and deserializing 64-byte private/public keypairs. Such APIs and serializations are inherently unsafe as the public key is one of the inputs used in the deterministic computation of the `S` part of the signature, but not in the `R` value. An adversary could somehow use the signing function as an oracle that allows arbitrary public keys as input can obtain two signatures for the same message sharing the same `R` and only differ on the `S` part. Unfortunately, when this happens, one can easily extract the private key. Revised public APIs in v2.0 of `ed25519-dalek` do NOT allow a decoupled private/public keypair as signing input, except as part of specially labeled "hazmat" APIs which are clearly labeled as being dangerous if misused.

Ubuntu Security Notice 6283-1 - Ruihan Li discovered that the bluetooth subsystem in the Linux kernel did not properly perform permissions checks when handling HCI sockets. A physically proximate attacker could use this to cause a denial of service. Zheng Zhang discovered that the device-mapper implementation in the Linux kernel did not properly handle locking during table_clear operations. A local attacker could use this to cause a denial of service.

Ubuntu Security Notice 6284-1 - It was discovered that the netlink implementation in the Linux kernel did not properly validate policies when parsing attributes in some situations. An attacker could use this to cause a denial of service. Billy Jheng Bing Jhong discovered that the CIFS network file system implementation in the Linux kernel did not properly validate arguments to ioctl in some situations. A local attacker could possibly use this to cause a denial of service.
