Background ========== ProFTPD is an advanced and very configurable FTP server. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 net-ftp/proftpd < 1.3.7c >= 1.3.7c Description =========== ProFTPd unconditionally sends passwords to Radius servers for authentication in multiples of 16 bytes. If a password is not of a length that is a multiple of 16 bytes, ProFTPd will read beyond the end of the password string and send bytes beyond the end of the string buffer. Impact ====== Radius servers used for authentication can receive the contents of the ProFTPd process' memory. Workaround ========== There is no known workaround at this time. Resolution ========== All ProFTPd users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=net-ftp/proftpd-1.3.7c" References ========== [ 1 ] CVE-2021-46854 https://nvd.nist.gov/vuln/detail/CVE-2021-46854 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: https://security.gentoo.org/glsa/202305-03 Concerns? ========= Security is a primary focus of Gentoo Linux and ensuring the confidentiality and security of our users' machines is of utmost importance to us.
