GNUnet is a peer-to-peer framework with focus on providing security. All peer-to-peer messages in the network are confidential and authenticated. The framework provides a transport abstraction layer and can currently encapsulate the network traffic in UDP (IPv4 and IPv6), TCP (IPv4 and IPv6), HTTP, or SMTP messages. GNUnet supports accounting to provide contributing nodes with better service. The primary service build on top of the framework is anonymous file sharing.

AMD Secure Encrypted Virtualization (SEV) is a hardware memory encryption feature. SEV protects guest virtual machines from the hypervisor, provides confidentiality guarantees at runtime and remote attestation at launch time. The SEV elliptic-curve (ECC) implementation was found to be vulnerable to an invalid curve attack. At launch-start command, an attacker can send small order ECC points not on the official NIST curves, and force the SEV firmware to multiply a small order point by the firmware's private DH scalar. By collecting enough modular residues, an attacker can recover the complete PDH private key. With the PDH, an attacker can recover the session key and the VM's launch secret. This breaks the confidentiality guarantees offered b.

Ubuntu Security Notice 4034-1 - It was discovered that ImageMagick incorrectly handled certain malformed image files. If a user or automated system using ImageMagick were tricked into opening a specially crafted image, an attacker could exploit this to cause a denial of service or possibly execute code with the privileges of the user invoking the program. Due to a large number of issues discovered in GhostScript that prevent it from being used by ImageMagick safely, the update for Ubuntu 18.10 and Ubuntu 19.04 includes a default policy change that disables support for the Postscript and PDF formats in ImageMagick. This policy can be overridden if necessary by using an alternate ImageMagick policy configuration. Various other issues were als.
