Bug#1004086: apache2-bin: mod_ssl ignores SSLOpenSSLConfCmd DHParameters
Package: apache2-bin
Version: 2.4.52-1~deb11u2
Severity: normal
Dear Maintainer,
I use a 4096-bit RSA certificate and corresponding 4096-bit DH parameters generated with
openssl dhparam -outform pem -out /etc/apache2/ssl/dhparam4k.pem 4096
I configured these parameters in Apache with
SSLOpenSSLConfCmd DHParameters /etc/apache2/ssl/dhparam4k.pem
Since the upgrade to Bullseye, these parameters seem to be ignored:
sslscan and ssllabs show that my DHE parameters are only 3072 bits.
When I test the same configuration on a Buster machine the correct 4096 bits are shown.
