Detail

Yutaka Oiwa discovered a vulnerability in the Open Secure Socket Layer (OpenSSL) library that can allow an attacker to perform active protocol-version rollback attacks that could lead to the use of the weaker SSL 2.0 protocol even though both ends support SSL 3.0 or TLS 1.0.

The following matrix explains which version in which distribution has this problem corrected.

oldstable (woody) stable (sarge) unstable (sid) openssl 0.9.6c-2.woody.8 0.9.7e-3sarge1 0.9.8-3 openssl 094 0.9.4-6.woody.4 n/a n/a openssl 095 0.9.5a-6.woody.6 n/a n/a openssl 096 n/a 0.9.6m-1sarge1 n/a openssl 097 n/a n/a 0.9.7g-5

We recommend that you upgrade your libssl packages.
