New serious openssl vulnerabilities

OpenSSL has announced several new vulnerabilities that affect clients and servers that use OpenSSL.

The various vulnerabilities, if exploited, would allow an attacker to:

  • conduct a man-in-the-middle attack
  • deny service
  • execute arbitrary code.


As this was a properly coordinated release, many vendors already have patches including RedtHat, Debian and others.
