Details
Mark Dowd discovered an off-by-one buffer overflow in the mod_rewrite
module’s ldap scheme handling. On systems which activate
“RewriteEngine on”, a remote attacker could exploit certain rewrite
rules to crash Apache, or potentially even execute arbitrary code
(this has not been verified).
“RewriteEngine on” is disabled by default. Systems which have this
directive disabled are not affected at all.
