Package: apache2
Version: 2.4.35-1
Severity: important
After a recent upgrade, apache2 does not start any more:
tglase@tglase:~ $ cat /var/log/apache2/error.log
[Mon Oct 29 20:18:58.090841 2018] [ssl:emerg] [pid 17306] AH01903: Failed to
configure CA certificate chain!
[Mon Oct 29 20:18:58.090919 2018] [ssl:emerg] [pid 17306] AH02311: Fatal error
initialising mod_ssl, exiting. See /var/log/apache2/error.log for more
information
AH00016: Configuration Failed
The certificate itself and the chain are ok, though:
tglase@tglase:~ $ openssl verify -CApath /etc/ssl/certs -show_chain -purpose
sslserver -verify_hostname tglase.lan.tarent.de -untrusted
/etc/ssl/W_lan_tarent_de.ca /etc/ssl/W_lan_tarent_de.cer
/etc/ssl/W_lan_tarent_de.cer: OK
Chain:
depth=0: CN = *.lan.tarent.de (untrusted)
depth=1: C = US, O = DigiCert Inc, OU = www.digicert.com, CN = RapidSSL TLS RSA
CA G1 (untrusted)
depth=2: C = US, O = DigiCert Inc, OU = www.digicert.com, CN = DigiCert Global
Root G2
Postfix, on the same system, using the same certificates…
smtpd_tls_cert_file = /etc/ssl/W_lan_tarent_de.cer
smtpd_tls_key_file = /etc/ssl/private/W_lan_tarent_de.key
smtpd_tls_CAfile = /etc/ssl/W_lan_tarent_de.ca
… runs fine, so this must be some regression in Apache2.

# A self-signed (snakeoil) certificate can be created by
installing

# /usr/share/doc/apache2/README.Debian.gz for more info.
# If both key and certificate are stored in the same file,
only the
# SSLCertificateFile directive is needed.
#SSLCertificateFile /etc/ssl/certs/ssl-cert-snakeoil.pem
#SSLCertificateKeyFile /etc/ssl/private/ssl-cert-snakeoil.key
# Server Certificate Chain:
# Point SSLCertificateChainFile at a file containing the
# concatenation of PEM encoded CA certificates which form the
# certificate chain for the server certificate. Alternatively
# the referenced file can be the same as SSLCertificateFile
# when the CA certificates are directly appended to the server
# certificate for convinience.
#SSLCertificateChainFile /etc/apache2/ssl.crt/server-ca.crt
# Certificate Authority (CA):
# Set the CA certificate verification path where to find CA
# certificates for client authentication or alternatively one
# huge file containing all of them (file must be PEM encoded)
# Note: Inside SSLCACertificatePath you need hash symlinks
# to point to the certificate files. Use the
provided
# Makefile to update the hash symlinks after
changes.
#SSLCACertificatePath /etc/ssl/certs/
#SSLCACertificateFile /etc/apache2/ssl.crt/ca-bundle.crt
# Certificate Revocation Lists (CRL):
# Set the CA revocation path where to find CA CRLs for client
# authentication or alternatively one huge file containing all
# of them (file must be PEM encoded)
# Note: Inside SSLCARevocationPath you need hash symlinks
# to point to the certificate files. Use the
provided
# Makefile to update the hash symlinks after
changes.
#SSLCARevocationPath /etc/apache2/ssl.crl/
#SSLCARevocationFile /etc/apache2/ssl.crl/ca-bundle.crl
# Client Authentication (Type):
# Client certificate verification type and depth. Types are
# none, optional, require and optional_no_ca. Depth is a
# number which specifies how deeply to verify the certificate
# issuer chain before deciding the certificate is not valid.
#SSLVerifyClient require
#SSLVerifyDepth 10
# SSL Engine Options:
# Set various options for the SSL engine.
# o FakeBasicAuth:
# Translate the client X.509 into a Basic Authorisation.
This means that
# the standard Auth/DBMAuth methods can be used for
access control. The
# user name is the `one line' version of the client's
X.509 certificate.
# Note that no password is obtained from the user. Every
entry in the user
# file needs this password: `xxj31ZMTZzkVA'.
# o ExportCertData:
# This exports two additional environment variables:
SSL_CLIENT_CERT and
# SSL_SERVER_CERT. These contain the PEM-encoded
certificates of the
# server (always existing) and the client (only existing
when client
# authentication is used). This can be used to import
the certificates
# into CGI scripts.
# o StdEnvVars:
# This exports the standard SSL/TLS related `SSL_*'
environment variables.
# Per default this exportation is switched off for
performance reasons,
# because the extraction step is an expensive operation
and is usually
# useless for serving static content. So one usually
enables the
# exportation for CGI and SSI requests only.
# o OptRenegotiate:
# This enables optimized SSL connection renegotiation
handling when SSL
# directives are used in per-directory context.

# SSL Protocol Adjustments:
# The safe and default but still SSL/TLS standard compliant
shutdown
# approach is that mod_ssl sends the close notify alert but
doesn't wait for
# the close notify alert from client. When you need a
different shutdown
# approach you can use one of the following variables:
# o ssl-unclean-shutdown:
# This forces an unclean shutdown when the connection is
closed, i.e. no
# SSL close notify alert is send or allowed to received.
This violates
# the SSL/TLS standard but is needed for some brain-dead
browsers. Use
# this when you receive I/O errors because of the
standard approach where
# mod_ssl sends the close notify alert.
# o ssl-accurate-shutdown:
# This forces an accurate shutdown when the connection
is closed, i.e. a
# SSL close notify alert is send and mod_ssl waits for
the close notify
# alert of the client. This is 100% SSL/TLS standard
compliant, but in
# practice often causes hanging connections with
brain-dead browsers. Use
# this only for browsers where you know that their SSL
implementation
# works correctly.
# Notice: Most problems of broken clients are also related to
the HTTP
# keep-alive facility, so you usually additionally want to
disable
# keep-alive for those clients, too. Use variable
"nokeepalive" for this.
# Similarly, one has to force some clients to use HTTP/1.0 to
workaround
# their broken HTTP/1.1 implementation. Use variables
"downgrade-1.0" and
# "force-response-1.0" for this.
