Debian Security Advisory

DSA-253-1 openssl -- information leak

Date Reported:

24 Feb 2003

Affected Packages:

openssl

Vulnerable:

Yes

Security database references:

In the Bugtraq database (at SecurityFocus): BugTraq ID 6884.
In Mitre's CVE dictionary: CVE-2003-0078.

More information:

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.

Fixed in:

Debian GNU/Linux 2.2 (potato)
