CVE-2015-3455

Published: 18 May 2015

Squid 3.2.x before 3.2.14, 3.3.x before 3.3.14, 3.4.x before 3.4.13, and 3.5.x before 3.5.4, when configured with client-first SSL-bump, do not properly validate the domain or hostname fields of X.509 certificates, which allows man-in-the-middle attackers to spoof SSL servers via a valid certificate.

Notes

AuthorNote
mdeslaur
only an issue if squid3 is built with --enable-ssl, which isn't
the case on debian/ubuntu for licensing reasons.
However, we should probably fix this anyway as rebuilding
the Ubuntu package locally to enable ssl is a common scenario.
3.1.x not affected
