Versions of the ab (ApacheBench) support program bundled with versions of apache prior to 1.3.27 contain pssibly-exploitable buffer overflows. The shared memory scoreboard used in versions of apache prior to 1.3.27 can be abused by the UID the server is running as (typically "apache") to trick the top-most parent httpd process into sending a SIGUSR1 signal to any running process. Versions of apache prior to 1.3.27 can also be used in cross-site scripting attacks if wildcard DNS is enabled at the web server and the server is configured to not canonicalize host names.
