SSL/TLS: Padding Oracle On Downgraded Legacy Encryption attack
A flaw was found in the way SSL 3.0 handled padding bytes when decrypting messages encrypted using block ciphers in cipher block chaining CBC mode. This flaw allows a man-in-the-middle MITM attacker to decrypt a selected byte of a cipher text in as few as 256 tries if they are able to force a...

Scientific Linux Security Update : openssl on SL5.x i386/x86_64 (20141016) (POODLE)
This update adds support for the TLS Fallback Signaling Cipher Suite Value TLSFALLBACKSCSV, which can be used to prevent protocol downgrade attacks against applications which re-connect using a lower SSL/TLS protocol version when the initial connection indicating the highest supported protocol...
OpenSSL 3.0 Protocol Vulnerability
US-CERT is aware of a design vulnerability found in the way SSL 3.0 handles block cipher mode padding. Exploitation of this vulnerability may allow a remote attacker to decrypt and extract information from inside an encrypted transaction. US-CERT recommends users and administrators review TA14-29...
SSL Padding Oracle On Downgraded Legacy Encryption (POODLE) Vulnerability
On October 14, 2014, a vulnerability was publicly announced in the Secure Sockets Layer version 3 SSLv3 protocol when using a block cipher in Cipher Block Chaining CBC mode. SSLv3 is a cryptographic protocol designed to provide communication security, which has been superseded by Transport Layer...
Cisco Releases Open Source FNR Cipher
Cisco has released a new open-source block cipher called FNR that is designed for encrypting small chunks of data, such as MAC addresses or IP addresses. The cipher is still in the experimental stage, but Cisco has released the source code and a demo application. The company suggests that the new...
Cisco Open Sources Experimental Small Domain Block Cipher
In cryptography, Block ciphers such as AES or DES are a symmetric key cipher operating on fixed-length groups of bits, called blocks, and typically operate on large input data blocks i.e. 64 or more than 128, 256 bits. Block cipher encrypts Plain-text to Cipher-text by applying cryptographic key...
AIX OpenSSL Advisory : openssl_advisory3.asc
The version of OpenSSL running on the remote host is affected by the following vulnerabilities : - The DTLS implementation in OpenSSL before 0.9.8s and 1.x before 1.0.0f performs a MAC check only if certain padding is valid, which makes it easier for remote attackers to recover plaintext via a...
Juniper Steel-Belted Radius Multiple OpenSSL Vulnerabilities
The version of Juniper Steel-Belted Radius software installed on the remote RedHat or CentOS host is affected by multiple OpenSSL vulnerabilities : - The SSL 3.0 implementation in OpenSSL does not properly initialize data structures for block cipher padding, which could allow remote attackers to...
Debian Security Advisory DSA 2697-1 (gnutls26 - out-of-bounds array read)
It was discovered that a malicious client could crash a GNUTLS server and vice versa, by sending TLS records encrypted with a block cipher which contain invalid padding. The oldstable distribution squeeze is not affected because the security fix that introduced this vulnerability was not applied ...

Medium: openssl
Issue Overview: An integer underflow flaw, leading to a buffer over-read, was found in the way OpenSSL handled DTLS Datagram Transport Layer Security application data record lengths when using a block cipher in CBC cipher-block chaining mode. A malicious DTLS client or server could use this flaw ...
gnutls: TLS record handling issue (GNUTLS-SA-2012-2, MU-201202-01)
gnutlscipher.c in libgnutls in GnuTLS before 2.12.17 and 3.x before 3.0.15 does not properly handle data encrypted with a block cipher, which allows remote attackers to cause a denial of service heap memory corruption and application crash via a crafted record, as demonstrated by a crafted...
