Nextcloud End-to-End Encryption before 1.5.3, 1.6.3 and 1.7.1 suffers from a denial of service vulnerability due to permitting any authenticated users to lock files of other users.

The AES encryption project 7.x and 8.x for Drupal does not sufficiently prevent attackers from decrypting data, aka SA-CONTRIB-2017-027. NOTE: This project is not covered by Drupal's security advisory policy.

A weak robustness vulnerability exists in the AWS Encryption SDKs for Java, Python, C and Javalcript prior to versions 2.0.0. Due to the non-committing property of AES-GCM (and other AEAD ciphers such as AES-GCM-SIV or (X)ChaCha20Poly1305) used by the SDKs to encrypt messages, an attacker can craft a unique cyphertext which will decrypt to multiple different results, and becomes especially relevant in a multi-recipient setting. We recommend users update their SDK to 2.0.0 or later.

IBM Security Guardium Data Encryption (GDE) 3.0.0.2 allows web pages to be stored locally which can be read by another user on the system. IBM X-Force ID: 171926.

IBM Security Guardium Data Encryption (GDE) 3.0.0.2 stores user credentials in plain in clear text which can be read by an authenticated user. IBM X-Force ID: 171938.

IBM Security Guardium Data Encryption (GDE) 3.0.0.2 could allow a remote attacker to obtain sensitive information, caused by the failure to properly enable HTTP Strict Transport Security. An attacker could exploit this vulnerability to obtain sensitive information using man in the middle techniques. IBM X-Force ID: 171826.

IBM Security Guardium Data Encryption (GDE) 3.0.0.2 is deployed with active debugging code that can create unintended entry points. IBM X-Force ID: 171936.

IBM Security Guardium Data Encryption (GDE) 3.0.0.2 is vulnerable to cross-site scripting. This vulnerability allows users to embed arbitrary JavaScript code in the Web UI thus altering the intended functionality potentially leading to credentials disclosure within a trusted session. IBM X-Force ID: 171828.

IBM Security Guardium Data Encryption (GDE) 3.0.0.2 generates an error message that includes sensitive information about its environment, users, or associated data. IBM X-Force ID: 171931.

IBM Security Guardium Data Encryption (GDE) 3.0.0.2 does not require that users should have strong passwords by default, which makes it easier for attackers to compromise user accounts. IBM X-Force ID: 171929.
