Detail
| The elliptic curve cryptography (ECC) subsystem in OpenSSL 1.0.0d and earlier, when the Elliptic Curve Digital Signature Algorithm (ECDSA) is used for the ECDHE_ECDSA cipher suite, does not properly implement curves over binary fields, which makes it easier for context-dependent attackers to determine private keys via a timing attack and a lattice calculation. |

| Title: | DSA-2309-1 openssl -- compromised certificate authority | ||
| Description: | Several fraudulent SSL certificates have been found in the wild issued by the DigiNotar Certificate Authority, obtained through a security compromise of said company. After further updates on this incident, it has been determined that all of DigiNotar's signing certificates can no longer be trusted. Debian, like other software distributors and vendors, has decided to distrust all of DigiNotar's CAs. In this update, this is done in the crypto library by marking such certificates as revoked. Any application that uses said component should now reject certificates signed by DigiNotar. Individual applications may allow users to overrride the validation failure. However, making exceptions is highly discouraged and should be carefully verified. Additionally, a vulnerability has been found in the ECDHE_ECDS cipher where timing attacks make it easier to determine private keys. The Common Vulnerabilities and Exposures project identifies it as CVE-2011-1945. | ||
