Dist Opensuse Esm H88
Safeguard your openSUSE environment by applying the current uftpd patch that mitigates a moderate service interruption vulnerability.
An update that fixes one vulnerability is now available.

Description

This update for uftpd fixes the following issues:

uftpd was updated to version 2.12.

Changes:

* Use common log message format and log level when user enters an invalid

path. This unfortunately affects changes introduced in v2.11 to increase

logging at default log level.

Security fixes:

- CVE-2020-14149: When entering an invalid directory with the FTP command

CWD, a NULL ptr was deref. in a DBG() message even though the log level

is set to a value lower than LOG_DEBUG. This caused uftpd to crash and

cause denial of service. Depending on the init/inetd system used this

could be permanent. (boo#1172959)
