Apache mod_rewrite is prone to an off-by-one buffer-overflow condition. The vulnerability arising in the mod_rewrite module's ldap scheme handling allows for potential memory corruption when an attacker exploits certain rewrite rules.

Affected Apache versions:

  • Apache 1.3.28 - 1.3.36 with mod_rewrite
  • Apache 2.2.0 - 2.2.2 with mod_rewrite
  • Apache 2.0.46 - 2.0.58 with mod_rewrite


Impact

Recommendation
Upgrade Apache to the latest version.
