Buffer overflow in the tls_x509_name_oneline function in the mod_tls module, as used in ProFTPD 1.3.0a and earlier, and possibly other products, allows remote attackers to execute arbitrary code via a large data length argument, a different vulnerability than CVE-2006-5815.

ProFTPD 1.3.0a and earlier does not properly set the buffer size limit when CommandBufferSize is specified in the configuration file, which leads to an off-by-two buffer underflow. NOTE: in November 2006, the role of CommandBufferSize was originally associated with CVE-2006-5815, but this was an error stemming from a vague initial disclosure. NOTE: ProFTPD developers dispute this issue, saying that the relevant memory location is overwritten by assignment before further use within the affected function, so this is not a vulnerability

Buffer overflow in mod_radius in ProFTPD before 1.3.0rc2 allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via a long password.

ProFTPD 1.2.9 treats the Allow and Deny directives for CIDR based ACL entries as if they were AllowAll, which could allow FTP clients to bypass intended access restrictions.

SQL injection vulnerability in ProFTPD Server 1.3.1 through 1.3.2rc2 allows remote attackers to execute arbitrary SQL commands via a "%" (percent) character in the username, which introduces a "'" (single quote) character during variable substitution by mod_sql.

Format string vulnerability in ProFTPD 1.2.0rc2 may allow attackers to execute arbitrary commands by shutting down the FTP server while using a malformed working directory (cwd).

mod_sqlpw module in ProFTPD does not reset a cached password when a user uses the "user" command to change accounts, which allows authenticated attackers to gain privileges of other users.
