Debian DSA-1816-1 : apache2 - insufficient security check

medium Nessus Plugin ID 39439

Synopsis

The remote Debian host is missing a security-related update.

Description

It was discovered that the Apache web server did not properly handle the 'Options=' parameter to the AllowOverride directive :

- In the stable distribution (lenny), local users could (via .htaccess) enable script execution in Server Side Includes even in configurations where the AllowOverride directive contained only Options=IncludesNoEXEC.
- In the oldstable distribution (etch), local users could (via .htaccess) enable script execution in Server Side Includes and CGI script execution in configurations where the AllowOverride directive contained any 'Options=' value.

The oldstable distribution (etch), this problem has been fixed in version 2.2.3-4+etch8.

Solution

Upgrade the apache2 packages.

For the stable distribution (lenny), this problem has been fixed in version 2.2.9-10+lenny3.

This advisory also provides updated apache2-mpm-itk packages which have been recompiled against the new apache2 packages (except for the s390 architecture where updated packages will follow shortly).
