Title: Apache Web Server Remote IPv6 Buffer Overflow Vulnerability

Severity: CRITICAL

Description:

Apache Web Server is reportedly affected by a remote buffer overflow vulnerability. This issue is due to a buffer boundary condition error that fails to provide a valid string length parameter while using libc memory copy functions.

The problem is reported to present itself when the affected web server attempts to parse a malicious or malformed URI when using IPv6. Apparently an attacker may send a malicious URI request to the affected server and cause it to send a negative value of a string length to a 'memcpy()' function call. This call takes place in the 'apr_uri_parse()' function of the affected server.

It has been reported that this issue can be exploited to execute arbitrary code on computers running BSD based Unix variants. This issue is reportedly due to the implementation of the 'memcpy()' function.

On Linux based Unix variants this issue can only be exploited to trigger a denial of service condition.
