Subject: [9.20] chg: usr: named could crash on concurrent TKEY DELETE for the same key
X-Git-Url: http://git.ipfire.org/gitweb/index.cgi?a=commitdiff_plain;h=dd02abde672e76166b4c8bacf6f274a85b743d3e;p=thirdparty%2Fbind9.git

[9.20] chg: usr: named could crash on concurrent TKEY DELETE for the same key

On a server configured with tkey-gssapi-keytab (or tkey-gssapi-credential),
an authenticated peer could crash named by sending two TKEY DELETE requests
for the same dynamic key in rapid succession.  This has been fixed.

Closes #6001
