openSUSE Security Update: Security update for proftpd ______________________________________________________________________________ Announcement ID: openSUSE-SU-2017:1035-1 Rating: moderate References: #1032443 Cross-References: CVE-2017-7418 Affected Products: openSUSE Leap 42.2 openSUSE Leap 42.1 ______________________________________________________________________________ An update that fixes one vulnerability is now available. 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 Patch Instructions: To install this openSUSE Security Update use YaST online_update.
