Also it was discovered that the oldstable distribution (etch) is not affected by the security issues. For reference the original advisory follows.

Two SQL injection vulnerabilities have been found in proftpd, a virtual-hosting FTP daemon. The Common Vulnerabilities and Exposures project identifies the following problems:

CVE-2009-0542

Shino discovered that proftpd is prone to an SQL injection vulnerability via the use of certain characters in the username.

CVE-2009-0543

TJ Saunders discovered that proftpd is prone to an SQL injection vulnerability due to insufficient escaping mechanisms, when multybite character encodings are used.

The oldstable distribution (etch) is not affected by these problems.

For the stable distribution (lenny), these problems have been fixed in version 1.3.1-17lenny2.

For the testing distribution (squeeze), these problems will be fixed soon.

For the unstable distribution (sid), these problems have been fixed in version 1.3.2-1.");
