Hi,

I searched crt.sh for valid certificates vulnerable to the 2008 Debian
weak key bug. (Only 2048 bit.)

Overall I found 5 unexpired certificates.

Two certificates by Certum (reported on Saturday, Certum told me "We
have taken necessary steps to clarify this situation as soon as
possible", they're not revoked yet):
https://crt.sh/?id=308392091&opt=ocsp
https://crt.sh/?id=6888863&opt=ocsp

Wosign:
https://crt.sh/?id=30347743
StartCom:
https://crt.sh/?id=54187884
https://crt.sh/?id=307753186

As we all know these are no longer trusted by Mozilla, I reported them
nevertheless. No reply yet.

Old bugs never die, I recommend every CA adds a check for the Debian
bug to their certificate issuance process.
