Name of the Vulnerable Software and Affected Versions OpenSSL versions 1.0.2b through 1.0.2o OpenSSL versions 1.1.0 through 1.1.0h Description The OpenSSL RSA Key generation algorithm is susceptible to a cache timing side channel attack. An attacker with sufficient access to mount cache timing...

VMSA-2018-0002 : VMware ESXi, Workstation and Fusion updates address side-channel analysis due to speculative execution. (Spectre)

Bounds Check bypass and Branch Target Injection issues CPU data cache timing can be abused to efficiently leak information out of mis-speculated CPU execution, leading to at worst arbitrary virtual memory read vulnerabilities across local security boundaries in various contexts. Speculative...

Reading privileged memory with a side-channel

Posted by Jann Horn, Project Zero We have discovered that CPU data cache timing can be abused to efficiently leak information out of mis-speculated execution, leading to at worst arbitrary virtual memory read vulnerabilities across local security boundaries in various contexts. Variants of this...

Libgcrypt Attack Allowed Recovery of RSA-1024 Keys

The cryptographic library Libgcrypt is vulnerable to a local side-channel attack; something researchers warn could allow full key recovery for RSA-1024. The vulnerability CVE-2017-7526 is tied to the fact that Libgcrypt, which is based on code from GnuPG, uses left to right sliding windows...

openSUSE Security Update : libressl (openSUSE-2017-222)

This update for libressl fixes the following issues : - CVE-2016-7056: Difficult to execute cache timing attack that may have allowed a local user to recover the private part from ECDSA P-256 keys boo1019334 %NASLMINLEVEL 70300 C Tenable Network Security, Inc. The descriptive text and package...

Cache-timing Attack

OpenSSL is vulnerable to a cache-timing attack. The attack exists due to a flaw in signing function of crypto/ecdsa/ecdsaossl.c which sets the BNFLGCONSTTIME flag for nonces instead of taking a secure code path in the BNmodinverse method...

OpenSSL ECDSA P-256 Private Key Acquisition Vulnerability

OpenSSL is an open source capable of implementing the Secure Sockets Layer SSL v2/v3 and Secure Transport Layer TLS v1 protocols developed by the OpenSSL team as a general-purpose cryptographic library that supports a wide range of cryptographic algorithms including symmetric ciphers, hash...

openssl -- timing attack vulnerability

Cesar Pereida Garcia reports: The signing function in crypto/ecdsa/ecdsaossl.c in certain OpenSSL versions and forks is vulnerable to timing attacks when signing with the standardized elliptic curve P-256 despite featuring constant-time curve operations and modular inversion. A software defect...

CVE-2016-7440

The C software implementation of AES Encryption and Decryption in wolfSSL formerly CyaSSL before 3.9.10 makes it easier for local users to discover AES keys by leveraging cache-bank timing differences...

nettle: RSA/DSA code is vulnerable to cache-timing related attacks

It was found that nettle's RSA and DSA decryption code was vulnerable to cache-related side channel attacks. An attacker could use this flaw to recover the private key from a co-located virtual-machine instance...

Ubuntu 14.04 LTS / 16.04 LTS : OpenSSL vulnerabilities (USN-3087-1)

The remote Ubuntu 14.04 LTS / 16.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-3087-1 advisory. Shi Lei discovered that OpenSSL incorrectly handled the OCSP Status Request extension. A remote attacker could possibly use this issue to cau...

OpenSSL -- vulnerability in DSA signing

The OpenSSL team reports: Operations in the DSA signing algorithm should run in constant time in order to avoid side channel attacks. A flaw in the OpenSSL DSA implementation means that a non-constant time codepath is followed for certain operations. This has been demonstrated through a...
