Vulnerability Assessment Details

[DSA844] DSA-844-1 mod-auth-shadow

Vulnerability Assessment Summary
DSA-844-1 mod-auth-shadow

Detailed Explanation for this Vulnerability Assessment

A vulnerability in mod_auth_shadow, an Apache module that lets users
perform HTTP authentication against /etc/shadow, has been discovered.
The module runs for all locations that use the 'require group'
directive which would bypass access restrictions controlled by another
authorisation mechanism, such as AuthGroupFile file, if the username
is listed in the password file and in the gshadow file in the proper
group and the supplied password matches against the one in the shadow
file.
This update requires an explicit "AuthShadow on" statement if website
authentication should be checked against /etc/shadow.
For the old stable distribution (woody) this problem has been fixed in
version 1.3-3.1woody.2.
For the stable distribution (sarge) this problem has been fixed in
version 1.4-1sarge1.
For the unstable distribution (sid) this problem has been fixed in
version 1.4-2.
We recommend that you upgrade your libapache-mod-auth-shadow package.
