[squid-users] [squid-announce] Squid 4.17 is available

[Amos Jeffries]

The Squid HTTP Proxy team is very pleased to announce the availability
of the Squid-4.17 release!


This release is a security release resolving a vulnerability
found in the prior Squid releases.


The major changes to be aware of:

  * SQUID-2020:12 Out-Of-Bounds memory access in WCCPv2
    (CVE-2021-28116 aka ZDI-CAN-11610)

  Due to an out of bounds memory access Squid is vulnerable to an
  information leak vulnerability when processing WCCPv2 messages.

  This problem allows a WCCPv2 sender to corrupt Squids list of
  known WCCP routers and divert client traffic to attacker
  controlled routers.

  This attack is limited to Squid proxy with WCCPv2 enabled and
  IP spoofing of a router IP address configured as trusted in
  squid.conf.


   All users of Squid are encouraged to upgrade as soon as possible.


See the ChangeLog for the full list of changes in this and earlier
releases.
