openSUSE Security Update : proftpd (openSUSE-2017-481)

medium Nessus Plugin ID 99430

Language:

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

Solution

Update the affected proftpd packages.
