New vsftpd packages are available for Slackware 11.0, 12.0, 12.1, 12.2, 13.0,
13.1, 13.37, and -current to work around a vulnerability in glibc.


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 *)
