CVE-2015-3455

Publication date 18 May 2015

Last updated 24 July 2024

Ubuntu priority

Negligible

Why this priority?

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

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
