Apache HTTP Server: mod_md NULL pointer dereference leads to child process crash
NULL pointer dereference vulnerability in Apache HTTP Server's mod_md during HTTP request processing. This issue affects Apache HTTP Server: from 2.4.30 through 2.4.69.
The strncasecmp function in the GNU C Library 2.24 and later optimized for the Power8 architecture may read one byte beyond the input size limit, which may crash a program when that byte is not readable. This condition may happen when the input strings to the strncasecmp function are attacker controlled in an application and they match all the way up to the edge of their page and the neighbouring page is either not mapped or is not readable.
