Description Tomas Hoger 2008-07-09 15:32:43 UTC

adminutil is a library of common functions used by multiple CGI scripts shipped
with Red Hat / Fedora Directory Server.

It was discovered that adminutil HTTP unescaping functions did not properly
handle %-encoded inputs, resulting in a miscalculation of memory requirement
needed to hold processed string with special characters replaced with HTML
entities.  This resulted in a heap-based overflow.  An attacker with access to
certain Directory Server's CGI scripts could use this flaw to crash or possibly
execute arbitrary code with the privileges of the Directory Server
Administration Server (unprivileged user, nobody by default, in affected
Directory Server versions).

Problem was introduced by a bug fix included in adminutil 1.1.6, affected
packages were only shipped in Fedora.

Red Hat Directory Server 7.1 and 8 did not contain vulnerable code.
