Description:
As undisclosed by an exploit (vd_proftpd.pm) and a related vendor
bugfix [0], a Denial of Sevice (DoS) vulnerability exists in the FTP
server ProFTPD [1], up to and including version 1.3.0. The flaw is
due to both a potential bus error and a definitive buffer overflow
in the code which determines the FTP command buffer size limit.
The vulnerability can be exploited only if the "CommandBufferSize"
directive is explicitly used in the server configuration -- which
is not the case in OpenPKG's default configuration of ProFTPD. The
Common Vulnerabilities and Exposures (CVE) project assigned the id
CVE-2006-5815 [2] to the problem.
