Description Olipro 2013-05-03 19:15:16 UTC
A serious vulnerability now exists in all versions of Strongswan prior to 5.0.4 whereby ECDSA is not properly handled when compiled with the openssl use flag ( CVE-2013-2944 ) thus permitting an attacker to generate an invalid ECDSA certificate and successfully authenticate.

Please bump Strongswan to 5.0.4 and consider a fast-track stabilisation.
Comment 1 Bjarke Istrup Pedersen (RETIRED) gentoo-dev 2013-05-04 06:09:40 UTC
Bumped to 5.0.4 - please stabilize ASAP.

Once stable, please remove version 5.0.0 from the tree, to prevent people installing that version, since it still has this issue.

Comment 2 GLSAMaker/CVETool Bot gentoo-dev 2013-05-09 12:09:12 UTC
CVE-2013-2944 (
  strongSwan 4.3.5 through 5.0.3, when using the OpenSSL plugin for ECDSA
  signature verification, allows remote attackers to authenticate as other
  users via an invalid signature.
