New bind packages are available for Slackware 8.1, 9.0, 9.1, 10.0, 10.1, 10.2, and 11.0 to fix security issues. The minimum OpenSSL version was raised to OpenSSL 0.9.7l and OpenSSL 0.9.8d to avoid exposure to known security flaws in older versions (these patches were already issued for Slackware). If you have not upgraded yet, get those as well to prevent a potentially exploitable security problem in named.
In addition, the default RSA exponent was changed from 3 to 65537.
Both of these issues are essentially the same as ones discovered in OpenSSL at the end of September 2006, only now there's protection against compiling using the wrong OpenSSL version. RSA keys using exponent 3 (which was previously BIND's default) will need to be regenerated to protect against the forging of RRSIGs.
More details about this issue may be found in the Common Vulnerabilities and Exposures (CVE) database:
Here are the details from the Slackware 11.0 ChangeLog:
patches/packages/bind-9.3.2_P2-i486-1_slack11.0.tgz: Upgraded to bind-9.3.2-P2. This fixes some security issues related to previous fixes in OpenSSL. The minimum OpenSSL version was raised to OpenSSL 0.9.7l and OpenSSL 0.9.8d to avoid exposure to known security flaws in older versions (these patches were already issued for Slackware). If you have not upgraded yet, get those as well to prevent a potentially exploitable security problem in named. In addition, the default RSA exponent was changed from 3 to 65537. RSA keys using exponent 3 (which was previously BIND's default) will need to be regenerated to protect against the forging of RRSIGs.

HINT: Getting slow download speeds from ftp.slackware.com? Give slackware.osuosl.org a try. This is another primary FTP site for Slackware that can be considerably faster than downloading from ftp.slackware.com.
Thanks to the friendly folks at the OSU Open Source Lab (http://osuosl.org) for donating additional FTP and rsync hosting to the Slackware project! :-)
