  script_tag(name:"insight", value:"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.

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.
