Comment 2 Paul Howarth 2023-12-28 15:14:53 UTC

EPEL-9 has proftpd 1.3.8a, which includes the fix for this issue, and version 1.3.8b is in testing.

I am in the process of building an update for proftpd-1.3.6e in EPEL-8 with a backported fix for this issue.

There is no fix needed for EPEL-7 because that has proftpd-1.3.5e and the out of bounds buffer read was introduced during the proftpd 1.3.6 development cycle as part of the fix for missing support for CR/LF characters in filenames (http://bugs.proftpd.org/show_bug.cgi?id=4167).
