Operating System: Debian GNU/Linux 8
Impact/Access: Denial of Service -- Unknown/Unspecified
Resolution: Patch/Upgrade
Original Bulletin:
https://www.debian.org/lts/security/2019/dla-1753
Revision History: May 2 2019: The update of proftpd-dfsg issued as

- --------------------------BEGIN INCLUDED TEXT--------------------

Hash: SHA512
Package : proftpd-dfsg
Version : 1.3.5e+r1.3.5-2+deb8u1
CVE ID : not available
Debian Bug : 923926 926719
The update of proftpd-dfsg issued as DLA-1753-1 caused a regression
when using the sftp module. Login to the sftp server was impossible
when the SFTPPAMEngine option was turned on (#926719).
This update reverts to upstream version 1.3.5 again since even the
latest upstream release 1.3.6 is still affected by different sftp
related bugs (#927270). All fixes for the memory leaks were backported
separately now.
For Debian 8 "Jessie", this problem has been fixed in version
1.3.5e+r1.3.5-2+deb8u1.
We recommend that you upgrade your proftpd-dfsg packages.

Several memory leaks were discovered in proftpd-dfsg, a versatile,
virtual-hosting FTP daemon, when mod_facl or mod_sftp
is used which could lead to memory exhaustion and a denial-of-service.
