Debian DLA-2115-2 : proftpd-dfsg regression update

high Nessus Plugin ID 133876

Language:

Synopsis

The remote Debian host is missing a security update.

Description

It was discovered that there was a regression in a previous fix for a use-after-free vulnerability in the proftpd-dfsg FTP server.

Exploitation of the original vulnerability within the memory pool handling could have allowed a remote attacker to execute arbitrary code on the affected system. However, the fix that was released in proftpd-dfsg version 1.3.5e+r1.3.5-2+deb8u6 had a regression around the handling of log formatting.

For more information, please see :

https://github.com/proftpd/proftpd/issues/903

For Debian 8 'Jessie', this issue has been fixed in proftpd-dfsg version 1.3.5e+r1.3.5-2+deb8u7.

We recommend that you upgrade your proftpd-dfsg packages.

NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Upgrade the affected packages.
