[slackware-security]  stunnel (SSA:2026-216-01)

New stunnel packages are available for Slackware 15.0 and -current to
fix security issues.


Here are the details from the Slackware 15.0 ChangeLog:
+--------------------------+
patches/packages/stunnel-5.80-i586-1_slack15.0.txz:  Upgraded.
  This update fixes security issues:
  Fixed an out-of-bounds memory access triggered by logging attacker-
  controlled protocol messages longer than 1,024 bytes.
  Fixed a SOCKS server mode bypass of the localhost destination filter
  using alternate local-address encodings and interface-scoped IPv6
  destinations.
