[daisy][PATCH 0/5] OpenSSL CVE fixes for the daisy branch

[Paul Eggleton]

NOTE: These patches needs to be applied *after* the OpenSSL
CVE-2010-5298 patch fix in Saul's pending daisy series (which is in
the branch for this pull request or it would not work otherwise.)


The following changes since commit:

  openssl: add openssl-CVE-2010-5298.patch SRC_URI (2014-06-09 14:11:54 +0100)

are available in the git repository at:

[daisy][PATCH 1/5] openssl: fix CVE-2014-0195

[Paul Eggleton]

From the OpenSSL Security Advisory [05 Jun 2014]
http://www.openssl.org/news/secadv_20140605.txt

DTLS invalid fragment vulnerability (CVE-2014-0195)

A buffer overrun attack can be triggered by sending invalid DTLS fragments
to an OpenSSL DTLS client or server. This is potentially exploitable to
run arbitrary code on a vulnerable client or server.

Only applications using OpenSSL as a DTLS client or server affected.

(Patch borrowed from Fedora.)

[daisy][PATCH 2/5] openssl: use upstream fix for CVE-2014-0198

[Paul Eggleton]

This replaces the fix for CVE-2014-0198 with one borrowed from Fedora,
which is the same as the patch which was actually applied upstream for
the issue, i.e.:

https://git.openssl.org/gitweb/?p=openssl.git;a=commit;h=b107586c0c3447ea22dba8698ebbcd81bb29d48c

[daisy][PATCH 3/5] openssl: fix CVE-2014-0221

[Paul Eggleton]

From the OpenSSL Security Advisory [05 Jun 2014]
http://www.openssl.org/news/secadv_20140605.txt

DTLS recursion flaw (CVE-2014-0221)

By sending an invalid DTLS handshake to an OpenSSL DTLS client the code
can be made to recurse eventually crashing in a DoS attack.

Only applications using OpenSSL as a DTLS client are affected.

(Patch borrowed from Fedora.)

[daisy][PATCH 4/5] openssl: fix CVE-2014-0224

[Paul Eggleton]

From the OpenSSL Security Advisory [05 Jun 2014]
http://www.openssl.org/news/secadv_20140605.txt

SSL/TLS MITM vulnerability (CVE-2014-0224)

An attacker using a carefully crafted handshake can force the use of weak
keying material in OpenSSL SSL/TLS clients and servers. This can be exploited
by a Man-in-the-middle (MITM) attack where the attacker can decrypt and
modify traffic from the attacked client and server.

The attack can only be performed between a vulnerable client *and*
server. OpenSSL clients are vulnerable in all versions of OpenSSL. Servers
are only known to be vulnerable in OpenSSL 1.0.1 and 1.0.2-beta1. Users
of OpenSSL servers earlier than 1.0.1 are advised to upgrade as a precaution.

(Patch borrowed from Fedora.)
