Package: libapache2-mod-perl2 Version: 2.0.4-7 Severity: important
I'm unable to disable <Perl> sections, as described here: http://perl.apache.org/docs/2.0/user/config/config.html#C_Perl_Handler_ Note: all configuration options below and screen output is indented by two spaces intentionally. Comments are not indented. So, according to the documentation, I should be able to simply place the following in the server configuration. PerlOption -Sections When the option is placed in the server configuration, the following error message is printed to screen when using apache2ctl configtest: Syntax error on line 10 of /etc/apache2/conf.d/all_vhosts: Invalid per-server PerlOption: Sections Action 'configtest' failed. The Apache error log may have more information. The apache error log does not have any information. This option is not allowed in per-directory configurations, and if I try to do so, Apache provides the following error message (IP address and path mangled): [Mon Oct 03 16:11:28 2011] [alert] [client aaa.bbb.ccc.ddd] /home/dir/.htaccess: Invalid per-directory PerlOption: Sections (only allowed per-server) As far as I can tell from the changelog, nothing has changed regarding this part of mod_perl 2 that would affect this feature between 2.0.4 (the version in Debian squeeze) and 2.0.5 (the current best version). Updating to 2.0.5 from testing is not an option, because of eager dependencies to newer versions of other packages. For my use, this bug is a security problem, as it makes it impossible to include mod_perl code to manage the Apache API in server configurations without permitting users to run Perl code in the same server, unless you also disable per-user configuration in .htaccess, which breaks other useful functionality. -- Package-specific info: -------------8<---------- Start Bug Report ------------8<---------- 1.
