Synopsis :

The remote openSUSE host is missing a security update.

Description :

This update for proftpd to version 1.3.5d fixes the following issues :

This security issue was fixed :

- CVE-2017-7418: ProFTPD checked only the last path
component when enforcing AllowChrootSymlinks. Attackers
with local access could bypass the AllowChrootSymlinks
control by replacing a path component (other than the
last one) with a symbolic link (bsc#1032443).

These non-security issues were fixed :

- Reduce TLS protocols to TLSv1.1 and TLSv1.2

- Disable TLSCACertificateFile

- Add TLSCertificateChainFile

- All FTP logins are treated as anonymous logins again

- SSH rekey during authentication could have caused issues
with clients.

- Recursive SCP uploads of multiple directories were not
handled properly.

- LIST returned different results for file, depending on
path syntax.

- 'AuthAliasOnly on' in server config broke anonymous
logins.

- Fixed memory leak when mod_facl is used.

- Fix systemd vs SysVinit inconsistency
