The rewrite as a single patch is here: http://svn.apache.org/viewvc/apr/apr/branches/1.4.x/strings/apr_fnmatch.c?r1=731029&r2=1098902 (In reply to comment #0) > It was reported that httpd exposes this problem via at least mod_autoindex > module, which allows remote users to specify pattern via P=pattern request > query argument: > > http://httpd.apache.org/docs/2.2/mod/mod_autoindex.html#query Mitigation: mod_autoindex can be configured to ignore request query arguments provided by the client by adding IgnoreClient option to the IndexOptions directive: http://httpd.apache.org/docs/2.2/mod/mod_autoindex.html#indexoptions.ignoreclient Fixed upstream in APR 1.4.4 and public now via: http://www.mail-archive.com/dev@apr.apache.org/msg23961.html http://www.apache.org/dist/apr/Announcement1.x.html Note especially a security fix to APR 1.4.4, stack overflow was possible due to unconstrained, recursive invocation of apr_fnmatch, as apr_fnmatch processed '*' wildcards. * Security: CVE-2011-0419 (http://cve.mitre.org) Reimplement apr_fnmatch() from scratch using a non-recursive algorithm; now has improved compliance with the fnmatch() spec.
