Secure your Apache server against LOGJAM

Some time ago I wrote a post about the dismaying history of US government attempts to regulate encryption out of existence . I had to omit quite a bit; it was a post and not a book after all. One of the details left out of the story was the DHE_EXPORT cipher suites. During the 90's, developers were forced by the US government to us deliberately insecure ciphers when communicating with entities in foreign countries (readers will remember from the last post that law makers were convinced that encryption should fall under the same rules as weapons technology, and thus could not be shared with anyone outside the Father Land). These insecure ciphers became DHE_EXPORT. The DH stands for Diffie-Hellman; the key exchange system that bears their name was first published in 1976. Along with the cipher suite was a mechanism to force a normal encrypted transaction to downshift to a lower-bit DHE_EXPORT cipher. As so many short-sighted technology regulations have done in the past, this silly

Massive Critical Security Patch Released by Oracle Impacting Most Versions of MySQL

Oracle has released a Critical Security Patch for a long list of Oracle products. For MySQL specifically, the patch purports to resolve a multitude of vulnerabilities that allow remote execution without authentication, and impact nearly all versions of the database software. Oracle provided the following Risk Matrix to their MySQL customers, which outlines the CVE numbers of stated vulnerabilities, the component used by the vulnerability and a number of other details. I've included a copy of that Matrix for readers to review below. As the reader can clearly see, the risk for unpatched MySQL users is huge. A total of 154 vulnerabilities are addressed with this update. Some of these vulnerabilities reach a forehead-slapping CVSS score of 9.0 (just one point beneath the score for  the recent Shellshock bash vulnerability ). 24 of the patches are for MySQL. I highly advise anyone using MySQL or any Oracle product, including Java, to  update their software immediately.
