ESPHome vulnerable to denial-of-service via out-of-bounds check bypass in the API component

Summary An integer overflow in the API component's protobuf decoder allows denial-of-service attacks when API encryption is not used. Details The bounds check ptr + fieldlength end in components/api/proto.cpp can overflow when a malicious client sends a large fieldlength value. This affects all...

CVE-2019-25005

An issue was discovered in the chacha20 crate before 0.2.3 for Rust. A ChaCha20 counter overflow makes it easier for attackers to determine plaintext...

Bkcrack - Crack Legacy Zip Encryption With Biham And Kocher's Known Plaintext Attack

Crack legacy zip encryption with Biham and Kocher's known plaintext attack. Overview A ZIP archive may contain many entries whose content can be compressed and/or encrypted. In particular, entries can be encrypted with a password-based Encryption Algorithm symmetric encryption algorithm referred ...

Nextcloud Server 19.0.1 Encryption Vulnerability (NC-SA-2020-039)

Nextcloud Server is prone to a vulnerability where it is possible to downgrade the encryption scheme and break the integrity through known-plaintext attack. SPDX-FileCopyrightText: 2020 Greenbone AG Some text descriptions might be excerpted from a referenced sources, and are Copyright C by the...

Insecure Encryption

Overview parsel is a gem to encrypt and decrypt data with a given key. Affected versions of this package are vulnerable to Insecure Encryption. In cases where an initialisation vector is not supplied to the encrypt or decrypt call in parsel.rb, the initialisation vector used by the library is set...

Nextcloud: Downgrade encryption scheme and break integrity through known-plaintext attack

The idea behind the Server Side Encryption is that you can move your encrypted files to an external party without that external party being able to to read or modify those files. Some time ago, Nextcloud switched from unauthenticated CFB cipher block mode to authenticated CTR cipher block mode in...

GHSA-4C4W-3Q45-HP9J Aescrypt does not sufficiently use random values

The aescrypt gem 1.0.0 for Ruby does not randomize the CBC IV for use with the AESCrypt.encrypt and AESCrypt.decrypt functions, which allows attackers to defeat cryptographic protection mechanisms via a chosen plaintext attack...

CVE-2013-7463

The CVE refers to the aescrypt gem (Ruby) version 1.0.0, where CBC IVs are not randomized for AESCrypt.encrypt and AESCrypt.decrypt. This omission enables a chosen-plaintext attack that defeats cryptographic protection. The NVD entry lists CVSS v3.0 base score 7.5 (HIGH) with network attack, no p...
