etc., etc.
I assume that libapache-auth-ldap applies only to Apache 1.3.x (it's
hard to tell while packages.d.o is out of action) - the original
Digital Armaments advisory [1] for this problem didn't specify any
particular version of Apache as being relevant.
At any rate, a recently installed Sarge box we have at work is running
Apache 2 with LDAP-based user authentication (against ADS) but doesn't
have libapache-auth-ldap installed.
This is what it has installed :
system42:~# COLUMNS=122 dpkg -l | grep apach
ii apache2-common 2.0.54-5 next generation, scalable,
extendable web server
ii apache2-doc 2.0.54-5 documentation for apache2
ii apache2-mpm-prefork 2.0.54-5 traditional model for Apache2
ii apache2-utils 2.0.54-5 utility programs for webservers
... and here's the LDAP-related section of apache.conf :
system42:~# grep -i ldap /etc/apache2/sites-available/secure
AuthLDAPEnabled on
AuthLDAPAuthoritative on
AuthLDAPUrl
ldap://my.work.com:3268/DC=my,DC=work,DC=com?SAMAccountName?sub?(objectClass=user)

>From this I infer that mod_auth_ldap for Debian-packaged Apache 2 must
be included with the main Debian Apache packages, and that no
libapache(2)-auth-ldap package is required - and that I therefore need
fixed Apache 2 packages. Is this so ?
If so, are fixed packages upcoming ?
Or is Debian Apache 2 unaffected by this security problem ?
Grateful for any clarification.
