Notes

Title of the patch
Security update for rage-encryption
Description of the patch
This update for rage-encryption fixes the following issues: -CVE-2023-42811: chosen ciphertext attack possible against aes-gcm (bsc#1215657) * update vendor.tar.zst to contain aes-gcm >= 0.10.3 - Update to version 0.9.2+0: * CI: Ensure `apt` repository is up-to-date before installing build deps * CI: Build Linux releases using `ubuntu-20.04` runner * CI: Remove most uses of `actions-rs` actions - Update to version 0.9.2+0: * Fix changelog bugs and add missing entry * Document `PINENTRY_PROGRAM` environment variable * age: Add `Decryptor::new_async_buffered` * age: `impl AsyncBufRead for ArmoredReader` * Pre-initialize vectors when the capacity is known, or use arrays * Use `PINENTRY_PROGRAM` as environment variable for `pinentry` * Document why `impl AsyncWrite for StreamWriter` doesn't loop indefinitely * cargo update * cargo vet prune * Migrate to `cargo-vet 0.7` * build(deps): bump svenstaro/upload-release-action from 2.5.0 to 2.6.1 * Correct spelling in documentation * build(deps): bump codecov/codecov-action from 3.1.1 to 3.1.4 * StreamWriter AsyncWrite: fix usage with futures::io::copy() * rage: Use `Decryptor::new_buffered` * age: Add `Decryptor::new_buffered` * age: `impl BufRead for ArmoredReader` * Update Homebrew formula to v0.9.1 * feat/pinentry: Use env var to define pinentry binary - Update to version 0.9.1+0: * ssh: Fix parsing of OpenSSH private key format * ssh: Support `aes256-gcm@openssh.com` ciphers for encrypted keys * ssh: Add `aes256-gcm@openssh.com` cipher to test cases * ssh: Extract common key material derivation logic for encrypted keys * ssh: Use associated constants for key and IV sizes * ssh: Add test cases for encrypted keys - Add shell completions for fish and zsh.

Starting in version 0.10.0 and prior to version 0.10.3, in the AES GCM implementation of decrypt_in_place_detached, the decrypted ciphertext (i.e. the correct plaintext) is exposed even if tag verification fails. If a program using the `aes-gcm` crate\u0027s `decrypt_in_place*` APIs accesses the buffer after decryption failure, it will contain a decryption of an unauthenticated input. Depending on the specific nature of the program this may enable Chosen Ciphertext Attacks (CCAs) which can cause a catastrophic breakage of the cipher including full plaintext recovery.
