This also includes the openssl-devel package. This is a security update. It fixes a vulnerability of the RSA encryption. The official security advisory follows: OpenSSL v0.9.7a and 0.9.6i vulnerability ---------------------------------------- Researchers have discovered a timing attack on RSA keys, to which OpenSSL is generally vulnerable, unless RSA blinding has been turned on. Typically, it will not have been, because it is not easily possible to do so when using OpenSSL to provide SSL or TLS. The enclosed patch switches blinding on by default. Applications that wish to can remove the blinding with RSA_blinding_off(), but this is not generally advised. It is also possible to disable it completely by defining OPENSSL_NO_FORCE_RSA_BLINDING at compile-time. The performance impact of blinding appears to be small (a few percent). This problem affects many applications using OpenSSL, in particular, almost all SSL-enabled Apaches. You should rebuild and reinstall OpenSSL, and all affected applications. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2003-0147 to this issue. We strongly advise upgrading OpenSSL in all cases, as a precaution. To update your installation, click on the "Install Cygwin now" link on the http://cygwin.com/ web page. This downloads setup.exe to your system. Once you've downloaded setup.exe, run it and select "Net" ("Devel" for the openssl-devel package) and then click on the appropriate field until the above announced version number appears if it is not displayed already. If you have questions or comments, please send them to the Cygwin mailing list at: cygwin AT cygwin DOT com . I would appreciate it if you would use this mailing list rather than emailing me directly. This includes ideas and comments about the setup utility or Cygwin in general. If you want to make a point or ask a question, the Cygwin mailing list is the appropriate place. *** CYGWIN-ANNOUNCE UNSUBSCRIBE INFO *** If you want to unsubscribe from the cygwin-announce mailing list, look at the "List-Unsubscribe: " tag in the email header of this message.
