Detail
| A vulnerability has been discovered in OpenSSL, a Secure Socket Layer (SSL) implementation. In an upcoming paper, Brice Canvel (EPFL), Alain Hiltgen (UBS), Serge Vaudenay (EPFL), and Martin Vuagnoux (EPFL, Ilion) describe and demonstrate a timing-based attack on CBC cipher suites used in SSL and TLS. OpenSSL has been found to vulnerable to this attack. For the stable distribution (woody) this problem has been fixed in version 0.9.6c-2.woody.2. For the old stable distribution (potato) this problem has been fixed in version 0.9.6c-0.potato.5. Please note that this updates the version from potato-proposed-updates that superseds the version in potato. For the unstable distribution (sid) this problem has been fixed in version 0.9.7a-1. We recommend that you upgrade your openssl packages. |

|---|---|
| 3945 | OpenSSL Vaudenay Timing Attack OpenSSL versions 0.9.6h and prior and 0.9.7 contains a flaw that may lead to an unauthorized information disclosure. The issue is triggered when a repeated block of plaintext in multiple OpenSSL/TLS sessions occur. A crafted block of ciphertext can be repeatedly injected into each session, which will kill that session but may ultimately lead to the disclosure of the repeated plaintext block, resulting in a loss of confidentiality. |
