[HIGH] squid3 regression
squid3 regression
USN-3557-1 fixed vulnerabilities in Squid. This update introduced a regression
which could cause the cache log to be filled with many Vary loop messages. This
update fixes the problem.
We apologize for the inconvenience.
Original advisory details:
Mathias Fischer discovered that Squid incorrectly handled certain long
strings in headers. A malicious remote server could possibly cause Squid to
crash, resulting in a denial of service. This issue was only addressed in
Ubuntu 16.04 LTS. (CVE-2016-2569)
William Lima discovered that Squid incorrectly handled XML parsing when
processing Edge Side Includes (ESI). A malicious remote server could
possibly cause Squid to crash, resulting in a denial of service. This issue
was only addressed in Ubuntu 16.04 LTS. (CVE-2016-2570)

CVE-2016-2570 [HIGH] CWE-617 squid: some code paths fail to check bounds in string object
squid: some code paths fail to check bounds in string object
The Edge Side Includes (ESI) parser in Squid 3.x before 3.5.15 and 4.x before 4.0.7 does not check buffer limits during XML parsing, which allows remote HTTP servers to cause a denial of service (assertion failure and daemon exit) via a crafted XML document, related to esi/CustomParser.cc and esi/CustomParser.h.
Incorrect boundary checks were found in the way squid handled headers in HTTP responses, which could lead to an assertion failure. A malicious HTTP server could use this flaw to crash squid using a specially crafted HTTP response.
Statement: Red Hat Product Security has rated this issue as having Moderate security impact. This issue is not currently planned to be addressed in future updates.

CVE-2016-2569 CVE-2016-2570 squid: some code paths fail to check bounds in string object
The proxy contains a String object class with 64KB content limits.
Some code paths do not bounds check before appending to these String
and overflow leads to an assertion which terminates all client
transactions using the proxy, including those unrelated to the limit
being exceeded.
