SWEET32: TLS 6 4-bit block cipher birthday attack(CVE-2 0 1 6-2 1 8 3)-vulnerability warning-the black bar safety net

The problem of the attack of harsh conditions. The attacker needs to get a lot of ciphertext, the thesis of the author is by 3 0 hours, 610GB of data to achieve. In addition, the need to plaintext in Important Information a lot of repetition which is to eventually be able to decrypt it's content,...

SSL/TLS: Cross-protocol attack on TLS using SSLv2 (DROWN)

A padding oracle flaw was found in the Secure Sockets Layer version 2.0 SSLv2 protocol. An attacker could potentially use this flaw to decrypt RSA-encrypted cipher text from a connection using a newer SSL/TLS protocol version, allowing them to decrypt such connections. This cross-protocol attack ...

The vulnerability of the Linter Bastion database management system allows a malicious individual to decode user credentials.

User accounts in a database are stored in the system table “$$$USR”. This table contains the names of users and their encrypted passwords. By default, the Linter Bastion database management system encrypts user passwords using the user’s name as the encryption key; that is, the encryption key is...

OpenSSL 1.0.1 < 1.0.1s Multiple Vulnerabilities

The version of OpenSSL installed on the remote host is prior to 1.0.1s. It is, therefore, affected by multiple vulnerabilities as referenced in the 1.0.1s advisory. - The SSLv2 protocol, as used in OpenSSL before 1.0.1s and 1.0.2 before 1.0.2g and other products, requires a server to send a...

CVE-2016-0800

The SSLv2 protocol, as used in OpenSSL before 1.0.1s and 1.0.2 before 1.0.2g and other products, requires a server to send a ServerVerify message before establishing that a client possesses certain plaintext RSA data, which makes it easier for remote attackers to decrypt TLS ciphertext data by...

CVE-2015-7756

VPN decryption vulnerability in Juniper ScreenOS (CVE-2015-7756) affects 6.2.0r15–6.2.0r18 and 6.3.0r12–6.3.0r20; encryption implementation allows a knowledgeable attacker monitoring ciphertext data to decrypt VPN traffic. Impact: confidentiality of VPN sessions can be compromised. No detection m...
