Description

<em style='font-weight:bold;'>(Description Provided by <a href="http://cve.mitre.org/cgi-bin/cvename.cgi?name=2005-1344" target="_blank">CVE</a>)</em> : 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.

Classification

Attack Type: Input Manipulation
Impact: Loss of Integrity
OSVDB: Web Related

Technical

The program htdigest is not SUID/SGID by default and can not be leveraged for additional privileges as a result of a default installation. This vulnerability only manifests if an administrator adds SUID or SGID privileges to the program, or if another program invokes it with increased privileges.
