Vulnerability Assessment Details

[DSA253] DSA-253-1 openssl

Vulnerability Assessment Summary
DSA-253-1 openssl

Detailed Explanation for this Vulnerability Assessment

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 be 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 supersedes 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.
