A flaw was found in httpd, where it incorrectly limits the value of the LimitXMLRequestBody option. This issue can lead to an integer overflow and later causes an out-of-bounds write.
Mitigation
Set the LimitXMLRequestBody option to a value smaller than 350MB. Setting it to 0 is not recommended as it will use a hard limit (depending on 32bit or 64bit systems) which may result in an overall system out-of-memory. The default configuration is not vulnerable to this flaw, see the statement above.
