Impact
A bug in the parsing of name constraint extensions in X.509 certificates meant that if the extension included both permitted subtrees and excluded subtrees, only the permitted subtree would be checked. If a certificate included a name which was permitted by the permitted subtree but also excluded by excluded subtree, it would be accepted.
Patches
Fixed in versions 3.5.0 and 2.19.5
Workarounds
No workaround available.
