|Gentoo Linux Security Advisory
Title: linux-ftpd-ssl: Remote buffer overflow (GLSA 200511-11)
Date: November 13, 2005
Updated: December 30, 2007
A buffer overflow vulnerability has been found, allowing a remote attacker to execute arbitrary code with escalated privileges on the local system.
linux-ftpd-ssl is the netkit FTP server with encryption support.
Vulnerable: < 0.17-r3
Unaffected: >= 0.17-r3
Architectures: All supported architectures
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.
All ftpd users should upgrade to the latest version:
|# emerge --sync
# emerge --ask --oneshot --verbose ">=net-ftp/netkit-ftpd-0.17-r3"
