This vulnerability (CVE-2015-0291) allows anyone to take a certificate, read its contents and modify it accurately to abuse the vulnerability causing a certificate to crash a client or server. If a client connects to an OpenSSL 1.0.2 server and renegotiates with an invalid signature algorithms extension, a null-pointer dereference occurs.
A value of 3 is for what is commonly called domain issued certificate (and DANE-EE). The TLSA record matches the used certificate itself. The used certificate does not need to be signed by other parties. This is useful for self-signed certificates, but also for cases where the validator does not have a list of trusted root certificates.
