Synopsis ========
Netkit FTP Server contains a Denial of Service vulnerability.
Background ==========
net-ftp/netkit-ftpd is the Linux Netkit FTP server with optional SSL support.
Affected packages =================
------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 net-ftp/netkit-ftpd < 0.17-r7 >= 0.17-r7
Description ===========
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.
Resolution ==========
All Netkit FTP Server users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=net-ftp/netkit-ftpd-0.17-r7"
