USN-1357-1: OpenSSL vulnerabilities

It was discovered that the elliptic curve cryptography ECC subsystem in OpenSSL, when using the Elliptic Curve Digital Signature Algorithm ECDSA for the ECDHEECDSA cipher suite, did not properly implement curves over binary fields. This could allow an attacker to determine private keys via a timi...

Medium: openssl

Issue Overview: It was discovered that the Datagram Transport Layer Security DTLS protocol implementation in OpenSSL leaked timing information when performing certain operations. A remote attacker could possibly use this flaw to retrieve plain text from the encrypted packets by using a DTLS serve...

FreeBSD : OpenSSL -- multiple vulnerabilities (78cc8a46-3e56-11e1-89b4-001ec9578670)

The OpenSSL Team reports : 6 security flaws have been fixed in OpenSSL 1.0.0f : If X509VFLAGPOLICYCHECK is set in OpenSSL 0.9.8, then a policy check failure can lead to a double-free. OpenSSL prior to 1.0.0f and 0.9.8s failed to clear the bytes used as block cipher padding in SSL 3.0 records. As ...

OpenSSL 1.0.0 < 1.0.0f Multiple Vulnerabilities

The version of OpenSSL installed on the remote host is prior to 1.0.0f. It is, therefore, affected by multiple vulnerabilities as referenced in the 1.0.0f advisory. - The GOST ENGINE in OpenSSL before 1.0.0f does not properly handle invalid parameters for the GOST block cipher, which allows remot...

Vulnerability in OpenSSL - Malformed RFC 3779 Data Can Cause Assertion Failures

RFC 3779 data can be included in certificates, and if it is malformed, may trigger an assertion failure. This could be used in a denial-of-service attack. Builds of OpenSSL are only vulnerable if configured with “enable-rfc3779”, which is not a default. Found by Andrew Chi...
