Description

Saulius Lapinskas discovered that Squid incorrectly handled processing HTTP conditional requests. A remote attacker could possibly use this issue to obtain sensitive information related to other clients' browsing sessions. (CVE-2016-10002)

Felix Hassert discovered that Squid incorrectly handled certain HTTP Request headers when using the Collapsed Forwarding feature. A remote attacker could possibly use this issue to obtain sensitive information related to other clients' browsing sessions. This issue only applied to Ubuntu 16.04 LTS and Ubuntu 16.10. (CVE-2016-10003).

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
