High Nessus Plugin ID 30242


The remote Gentoo host is missing one or more security-related patches.


The remote host is affected by the vulnerability described in GLSA-200801-17 (Netkit FTP Server: Denial of Service)

Venustech AD-LAB discovered that an FTP client connected to a vulnerable server with passive mode and SSL support can trigger an fclose() function call on an uninitialized stream in ftpd.c.
Impact :

A remote attacker can send specially crafted FTP data to a server with passive mode and SSL support, causing the ftpd daemon to crash.
Workaround :

Disable passive mode or SSL.


All Netkit FTP Server users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose '>=net-ftp/netkit-ftpd-0.17-r7'
