The version of Firefox ESR installed on the remote Mac OS X host is 45.x prior to 45.2. It is, therefore, affected by multiple vulnerabilities :
Multiple memory corruption issues exist that allow an unauthenticated, remote attacker to execute arbitrary code. (CVE-2016-2818)
An overflow condition exists that is triggered when handling HTML5 fragments in foreign contexts (e.g., under <svg> nodes). An unauthenticated, remote attacker can exploit this to cause a heap-based buffer overflow, resulting in the execution of arbitrary code.
(CVE-2016-2819)
A use-after-free error exists that is triggered when deleting DOM table elements in ‘contenteditable’ mode.
An unauthenticated, remote attacker can exploit this to dereference already freed memory, resulting in the execution of arbitrary code. (CVE-2016-2821)
A spoofing vulnerability exists due to improper handling of SELECT elements. An unauthenticated, remote attacker can exploit this to spoof the contents of the address bar. (CVE-2016-2822)
A use-after-free error exists that is triggered when destroying the recycle pool of a texture used during the processing of WebGL content. An unauthenticated, remote attacker can exploit this to dereference already freed memory, resulting in the execution of arbitrary code.
(CVE-2016-2828)
A flaw exists that is triggered when handling paired fullscreen and pointerlock requests in combination with closing windows. An unauthenticated, remote attacker can exploit this to create an unauthorized pointerlock, resulting in a denial of service condition.
Additionally, an attacker can exploit this to conduct spoofing and clickjacking attacks. (CVE-2016-2831)
