Debian Security Advisory

DSA-2833-1 openssl -- several vulnerabilities

Date Reported:

01 Jan 2014

Affected Packages:

openssl

Vulnerable:

Yes

Security database references:

In the Debian bugtracking system: Bug 732754, Bug 732710.
In Mitre's CVE dictionary: CVE-2013-6449, CVE-2013-6450.

More information:

Multiple security issues have been fixed in OpenSSL: The TLS 1.2 support was susceptible to denial of service and retransmission of DTLS messages was fixed. In addition this update disables the insecure Dual_EC_DRBG algorithm (which was unused anyway, see http://marc.info/?l=openssl-announce&m=138747119822324&w=2 for further information) and no longer uses the RdRand feature available on some Intel CPUs as a sole source of entropy unless explicitly requested.

For the stable distribution (wheezy), these problems have been fixed in version 1.0.1e-2+deb7u1.

For the unstable distribution (sid), these problems have been fixed in version 1.0.1e-5.

We recommend that you upgrade your openssl packages.
