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.

Cross Site Scripting (XSS) vulnerability in Query Report feature in Zoho ManageEngine Password Manager Pro version 11001, allows remote attackers to execute arbitrary code and steal cookies via crafted JavaScript payload.

A widely used Chinese language input app for Windows and Android has been found vulnerable to serious security flaws that could allow a malicious interloper to decipher the text typed by users. The findings from the University of Toronto's Citizen Lab, which carried out an analysis of the encryption mechanism used in Tencent's Sogou Input Method, an app that has over 455 million monthly active

gRPC contains a vulnerability that allows hpack table accounting errors could lead to unwanted disconnects between clients and servers in exceptional cases/ Three vectors were found that allow the following DOS attacks: - Unbounded memory buffering in the HPACK parser - Unbounded CPU consumption in the HPACK parser The unbounded CPU consumption is down to a copy that occurred per-input-block in the parser, and because that could be unbounded due to the memory copy bug we end up with an O(n^2) parsing loop, with n selected by the client. The unbounded memory buffering bugs: - The header size limit check was behind the string reading code, so we needed to first buffer up to a 4 gigabyte string before rejecting it as longer than 8 or 16kb. - HPACK varints have an encoding quirk whereby an infinite number of 0’s can be added at the start of an integer. gRPC’s hpack parser needed to read all of them before concluding a parse. - gRPC’s metadata overflow check was performed per frame, so ...
