GLSA-200511-11 : linux-ftpd-ssl: Remote buffer overflow
Critical Nessus Plugin ID 20198
SynopsisThe remote Gentoo host is missing one or more security-related patches.
DescriptionThe remote host is affected by the vulnerability described in GLSA-200511-11 (linux-ftpd-ssl: Remote buffer overflow)
A buffer overflow vulnerability has been found in the linux-ftpd-ssl package. A command that generates an excessively long response from the server may overrun a stack buffer.
An attacker that has permission to create directories that are accessible via the FTP server could exploit this vulnerability.
Successful exploitation would execute arbitrary code on the local machine with root privileges.
There is no known workaround at this time.
SolutionAll ftpd users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose '>=net-ftp/netkit-ftpd-0.17-r3'
