Package : proftpd-dfsg Version : 1.3.5e+r1.3.5-2+deb8u2 Debian Bug : 929020
The update of proftpd-dfsg issued as DLA-1753-1 caused a regression when the creation of a directory failed during sftp transfer. The sftp session would be terminated instead of failing gracefully due to a non-existing debug logging function.
For Debian 8 "Jessie", this problem has been fixed in version 1.3.5e+r1.3.5-2+deb8u2.
We recommend that you upgrade your proftpd-dfsg packages.
