Here are the details from the Slackware 13.37 ChangeLog:
+--------------------------+
patches/packages/vsftpd-2.3.5-i486-1_slack13.37.txz: Upgraded.
 Minor version bump, this also works around a hard to trigger heap overflow
 in glibc (glibc zoneinfo caching vuln). For there to be any possibility
 to trigger the glibc bug within vsftpd, the non-default option
 'chroot_local_user' must be set in /etc/vsftpd.conf.
 Considered 1) low severity (hard to exploit) and 2) not a vsftpd bug :-)
 Nevertheless:
 (* Security fix *)
+--------------------------+");
