[Secure-testing-team] Bug#683927: CVE-2012-3446: MITM vulnerability in TLS/SSL certificates verification
Package: libcloud Severity: grave Tags: security Justification: user security hole Hi, a new libcloud was released, fixing a MITM vulnerability in the TLS/SSL certificates verification. Basically the hostname/CN check is done using a wrong regular expression which will match even superset of the hostname. See http://libcloud.apache.org/security.html and https://github.com/apache/libcloud/commit/f2af5502dae3ac63e656dd1b7d5f29cc82ded401 and please upload an isolated fix to unstable, since we''re in freeze.
