Description Andrej Nemec 2016-02-16 05:26:57 EST

Due to incorrectly handling server errors Squid is vulnerable to
a denial of service attack when connecting to TLS or SSL servers.
This problem allows any trusted client to perform a denial of
service attack on the Squid service regardless of whether TLS or
SSL is configured for use in the proxy.

Comment 7 Cedric Buissart 2016-04-05 04:43:38 EDT

Statement:

This issue did not affect the versions of squid as shipped with Red Hat Enterprise Linux versions 5, 6 and 7, as they are not shipped with a vulnerable version of squid, and no currently backported patch would introduce the bug.
