Debian DSA-1217-1 : linux-ftpd - programming error

medium Nessus Plugin ID 23703

Synopsis

The remote Debian host is missing a security-related update.

Description

Paul Szabo discovered that the netkit ftp server switches the user id too late, which may lead to the bypass of access restrictions when running on NFS. This update also adds return value checks to setuid() calls, which may fail in some PAM configurations.

Solution

Upgrade the ftpd package.

For the stable distribution (sarge) this problem has been fixed in version 0.17-20sarge2.

For the upcoming stable distribution (etch) this problem has been fixed in version 0.17-22.
