Debian DLA-456-1 : openssl security update

Several vulnerabilities were discovered in OpenSSL, a Secure Socket Layer toolkit. CVE-2016-2105 Guido Vranken discovered that an overflow can occur in the function EVPEncodeUpdate, used for Base64 encoding, if an attacker can supply a large amount of data. This could lead to a heap corruption...

USN-2959-1: OpenSSL vulnerabilities

Huzaifa Sidhpurwala, Hanno Böck, and David Benjamin discovered that OpenSSL incorrectly handled memory when decoding ASN.1 structures. A remote attacker could use this issue to cause OpenSSL to crash, resulting in a denial of service, or possibly execute arbitrary code. CVE-2016-2108 Juraj...

CVE-2016-2107

It was discovered that OpenSSL leaked timing information when decrypting TLS/SSL and DTLS protocol encrypted records when the connection used the AES CBC cipher suite and the server supported AES-NI. A remote attacker could possibly use this flaw to retrieve plain text from encrypted packets by...

OpenSSL Patches Padding Oracle Attack Bug

The latest batch of OpenSSL security patches were released today, with a pair of high-severity flaws and four low-severity issues addressed in OpenSSL 1.0.1t and OpenSSL 1.0.2h. One of the high-severity flaws, CVE-2016-2107, opens the door to a padding oracle attack that can allow for the...

CVE-2016-2107

The AES-NI implementation in OpenSSL before 1.0.1t and 1.0.2 before 1.0.2h does not consider memory allocation during a certain padding check, which allows remote attackers to obtain sensitive cleartext information via a padding-oracle attack against an AES CBC session. NOTE: this vulnerability...

Vulnerability in OpenSSL - Padding oracle in AES-NI CBC MAC check

A MITM attacker can use a padding oracle attack to decrypt traffic when the connection uses an AES CBC cipher and the server support AES-NI. This issue was introduced as part of the fix for Lucky 13 padding attack CVE-2013-0169. The padding check was rewritten to be in constant time by making sur...

Name of the Vulnerable Software and Affected Versions Botan versions prior to 1.10.13 Botan versions 1.11.x prior to 1.11.22 Description The issue makes it easier for remote attackers to conduct million-message attacks by measuring time differences, related to the decoding of PKCS1 padding...

Oracle MySQL 5.7.x < 5.7.12 Multiple Vulnerabilities (RPM Check) (April 2016 CPU) (July 2016 CPU) (October 2017 CPU) (DROWN)

The version of Oracle MySQL installed on the remote host is 5.7.x prior to 5.7.12. It is, therefore, affected by the following vulnerabilities : - A cipher algorithm downgrade vulnerability exists in the bundled version of OpenSSL due to a flaw that is triggered when handling cipher negotiation. ...
