** Description changed:
See http://www.kb.cert.org/vuls/id/268267, VU#268267
opendkim in squeeze, wheezy, sid offers no method to prevent use of keys
less than 1024 bits. This is added in the new upstream release, 2.6.8, that
was released just for this issue.
+
+ [IMPACT]
+
+ * DKIM verifiers using opendkim will use insecure keys to produce valid
+ results.
+
+ [TESTCASE]
+
+ * The new functionality to limit key sizes is not easy to test, but is
covered by
+ additions to the test suite.
+
+ * In order to verify this package, it needs to be installed and tested that
it
+ generally works as before.
+
+ * Because of the specialized nature of this package, it's not possible to
produce
+ a test case that just anyone can verify.
+
+ [Regression Potential]
+
+ * Regression potential is very small as the only code changes in this
release are
+ the changes to resolve this issue.
+
+ [Other Info]
+
+ * Almost all of the diff is tool related noise. I've attached the non-noise
part
+ of the diff to this bug for reference. I think it's lower risk to just
update
+ to the new release to match what upstream is doing since there are no
other
+ changes in this release.
+
+ * The security team has reviewed this bug and said it should go via SRU and
not in
+ -security since it causes a config file change.
