GLSA-200611-05 : Netkit FTP Server: Privilege escalation

medium Nessus Plugin ID 23670

Synopsis

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

Description

The remote host is affected by the vulnerability described in GLSA-200611-05 (Netkit FTP Server: Privilege escalation)

 Paul Szabo reported that an incorrect seteuid() call after the chdir() function can allow an attacker to access a normally forbidden directory, in some very particular circumstances, for example when the NFS-hosted targetted directory is not reachable by the client-side root user. Additionally, some potentially exploitable unchecked setuid() calls were also fixed.
 Impact :

 A local attacker might craft his home directory to gain access through ftpd to normally forbidden directories like /root, possibly with writing permissions if seteuid() fails and if the ftpd configuration allows that. The unchecked setuid() calls could also lead to a root FTP login, depending on the FTP server configuration.
 Workaround :

 There is no known workaround at this time.

Solution

All Netkit FTP Server users should upgrade to the latest version:
 # emerge --sync # emerge --ask --oneshot --verbose '>=net-ftp/netkit-ftpd-0.17-r4'
