Description Ganesh 2026-11-03 02:31:47 UTC

Disclaimer: Community trackers are created by Red Hat Product Security team on a best effort basis. Package maintainers are required to ascertain if the flaw indeed affects their package, before starting the update process.

ProFTPD before 1.3.9e and 1.3.10rc5 contains a buffer overflow vulnerability in the mod_rewrite int:utf8trans RewriteMap that allows remote attackers to overwrite static buffers. Attackers can send FTP command arguments longer than 1024 bytes, without authentication if pre-login commands are rewritten, to corrupt session memory and crash the session.
