A flaw was found in the mod_macro module of httpd. When processing a very long macro, the null byte terminator will not be added, leading to an out-of-bounds read, resulting in a crash.

Mitigation

Disabling mod_macro and restarting httpd or making sure the macros used are smaller than the required length to trigger this vulnerability will mitigate this flaw. Furthermore, it's unlikely that a very long macro with the length needed to trigger this issue is being used.
