Mozilla Firefox < 49.0.2 Multiple Vulnerabilities

Versions of Mozilla Firefox prior to 49.0.2 are unpatched for the following vulnerabilities :

• An error is triggered during actor destruction with ‘service workers’. This may allow a context-dependent attacker to dereference already freed memory and potentially execute arbitrary code. (CVE-2016-5287)
• An unspecified flaw is triggered when e10s is disabled. This may allow a context-dependent attacker to use specially crafted web content to disclose potentially sensitive information in the HTTP cache related to page visits and content. (CVE-2016-5288)
