| Package | Affected versions | Patched versions |
|---|---|---|
| proftpd | < 1.3.6 | 1.3.6 |
An issue was discovered in tls_verify_crl in ProFTPD before 1.3.6. A wrong iteration variable, used when checking a client certificate against CRL entries (installed by a system administrator), can cause some CRL entries to be ignored, and can allow clients whose certificates have been revoked to proceed with a connection to the server.
