A vulnerability classified as critical was found in Apache HTTP Server 2.0.52 (Web Server). This vulnerability affects an unknown function of the component CGI Program. The manipulation of the argument realm with an unknown input leads to a memory corruption vulnerability. The CWE definition for the vulnerability is CWE-119. The product performs operations on a memory buffer, but it can read from or write to a memory location that is outside of the intended boundary of the buffer. As an impact it is known to affect confidentiality, integrity, and availability. CVE summarizes:

Buffer overflow in htdigest in Apache 2.0.52 may allow attackers to execute arbitrary code via a long realm argument. NOTE: since htdigest is normally only locally accessible and not setuid or setgid, there are few attack vectors which would lead to an escalation of privileges, unless htdigest is executed from a CGI program. Therefore this may not be a vulnerability.
