high Nessus Plugin ID 139758

Language:

Synopsis

The remote Debian host is missing a security update.

Description

The update of proftpd-dfsg released as DLA-2338-1 incorrectly destroyed the memory pool in function sftp_kex_handle in contrib/mod_sftp/kex.c which may cause a segmentation fault and thus prevent sftp connections.

For Debian 9 stretch, this problem has been fixed in version 1.3.5e+r1.3.5b-4+deb9u2.

We recommend that you upgrade your proftpd-dfsg packages.

For the detailed security status of proftpd-dfsg please refer to its security tracker page at:
https://security-tracker.debian.org/tracker/proftpd-dfsg

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.
