A bug in the protocol.c file handling header lines will cause Apache to
allocate memory for header lines starting with TAB or SPACE.
An attacker can exploit this vulnerability to perform a Denial of Service

to a buffer based overflow causing Apache to crash and under some
circumstances execute arbitrary code as the user running Apache, usually
There is no known workaround at this time. All users are encouraged to
upgrade to the latest available version:
