CVE-2016-0800 & CVE-2016-0703 OpenSSL vulnerabilities High Vendor OpenSSL Versions Affected SSLv2 Description 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 possess...

Code injection

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-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...

Crypto Panel Experts Clash on FBI-Apple Debate

SAN FRANCISCO—One would think that six of the smartest security people on the planet could come to some sort of collective conclusion on the FBI-Apple debate. But that wasn’t the case today during the annual Cryptographers’ Panel at RSA Conference. The debate over whether Apple should assist the...

ownCloud: DROWN Attack

Hi, I want to report a drown attack in .owncloud.com. A cross-protocol attack was discovered that could lead to decryption of TLS sessions by using a server supporting SSLv2 and EXPORT cipher suites as a Bleichenbacher RSA padding oracle. Note that traffic between clients and non-vulnerable serve...

openssl security update

CentOS Errata and Security Advisory CESA-2016:0301 Updated openssl packages that fix multiple security issues are now available for Red Hat Enterprise Linux 6 and 7. Red Hat Product Security has rated this update as having Important security impact. Common Vulnerability Scoring System CVSS base...

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 ...

USN-2914-1 openssl vulnerabilities

Yuval Yarom, Daniel Genkin, and Nadia Heninger discovered that OpenSSL was vulnerable to a side-channel attack on modular exponentiation. On certain CPUs, a local attacker could possibly use this issue to recover RSA keys. This flaw is known as CacheBleed. CVE-2016-0702 Adam Langley discovered th...

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-2016-0702

The MODEXPCTIMECOPYFROMPREBUF function in crypto/bn/bnexp.c in OpenSSL 1.0.1 before 1.0.1s and 1.0.2 before 1.0.2g does not properly consider cache-bank access times during modular exponentiation, which makes it easier for local users to discover RSA keys by running a crafted application on the...

Vulnerability in OpenSSL - Side channel attack on modular exponentiation

A side-channel attack was found which makes use of cache-bank conflicts on the Intel Sandy-Bridge microarchitecture which could lead to the recovery of RSA keys. The ability to exploit this issue is limited as it relies on an attacker who has control of code in a thread running on the same...

Network traffic encrypted using RSA-based SSL certificates over SSLv2 may be decrypted by the DROWN attack

Overview Network traffic encrypted using an RSA-based SSL certificate may be decrypted if enough SSLv2 handshake data can be collected. This is known as the "DROWN" attack in the media. Description According to the researcher, "DROWN" is a new form of cross-protocol Bleichenbacher padding oracle...

SSLv2 DROWN Attack

Network traffic encrypted using an RSA-based SSL certificate may be decrypted if enough SSLv2 handshake data can be collected. Exploitation of this vulnerability—referred to as DROWN in public reporting—may allow a remote attacker to decrypt individual messages from a server supporting SSLv2...
