Debian DSA-2767-1 : proftpd-dfsg - denial of service

medium Nessus Plugin ID 70201

Synopsis

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

Description

Kingcope discovered that the mod_sftp and mod_sftp_pam modules of proftpd, a powerful modular FTP/SFTP/FTPS server, are not properly validating input, before making pool allocations. An attacker can use this flaw to conduct denial of service attacks against the system running proftpd (resource exhaustion).

Solution

Upgrade the proftpd-dfsg packages.

For the oldstable distribution (squeeze), this problem has been fixed in version 1.3.3a-6squeeze7.

For the stable distribution (wheezy), this problem has been fixed in version 1.3.4a-5+deb7u1.
