GHSA-6H88-QJPV-P32M OpenSSL gem for Ruby using inadequate encryption strength

The OpenSSL gem for Ruby uses the same initialization vector IV in GCM Mode aes--gcm when the IV is set before the key, which makes it easier for context-dependent attackers to bypass the encryption protection mechanism...

CVE-2017-12871

The aesEncrypt method in lib/SimpleSAML/Utils/Crypto.php in SimpleSAMLphp 1.14.x through 1.14.11 makes it easier for context-dependent attackers to bypass the encryption protection mechanism by leveraging use of the first 16 bytes of the secret key as the initialization vector IV...

CVE-2017-12871

The CVE-2017-12871 issue affects SimpleSAMLphp (1.14.x–1.14.11) in the aesEncrypt method located at lib/SimpleSAML/Utils/Crypto.php. The root cause is using the first 16 bytes of the secret key as the initialization vector (IV), which enables context-dependent attackers to bypass the encryption p...

CVE-2017-11133

An issue was discovered in heinekingmedia StashCat through 1.7.5 for Android, through 0.0.80w for Web, and through 0.0.86 for Desktop. To encrypt messages, AES in CBC mode is used with a pseudo-random secret. This secret and the IV are generated with math.random in previous versions and with...

USN-3365-1 ruby1.9.1, ruby2.0, ruby2.3 vulnerabilities

It was discovered that Ruby DL::dlopen incorrectly handled opening libraries. An attacker could possibly use this issue to open libraries with tainted names. This issue only applied to Ubuntu 14.04 LTS. CVE-2009-5147 Tony Arcieri, Jeffrey Walton, and Steffan Ullrich discovered that the Ruby OpenS...

Archive Cryptography: unarcrypto

Archive Cryptography unarcrypto.py is an educational tool to depict the use of cryptography for password verification, headers and content encryption by popular archivers: zip, 7zip, rar v3 and v5. Supported archives format, encryption and compression algorithms: zip password protected or not,...

Insecure Encryption

aescrypt uses a vulnerable encryption method. The method is vulnerable because it does not randomize the CBC IV when encrypting and decrypting data. This allows attackers to easily defeat the cryptographic mechanism by guessing the CBC IV...

CVE-2013-7463

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...
