Mozilla Firefox Security Updates( mfsa_2017-18_2017-19 )-MAC OS X

Published: 2017-08-10 06:10:50
CVE Author: NIST National Vulnerability Database

CVSS Base Vector:

This host is installed with Mozilla Firefox and is prone to multiple vulnerabilities.

Detection Method:
Checks if a vulnerable version is present on the target host.

Technical Details:
The multiple flaws exists due to, - XUL injection in the style editor in devtools. - Use-after-free in WebSockets during disconnection. - Use-after-free with marquee during window resizing. - Use-after-free while deleting attached editor DOM node. - Use-after-free with image observers. - Use-after-free resizing image elements. - Buffer overflow manipulating ARIA attributes in DOM. - Buffer overflow while painting non-displayable SVG. - Use-after-free in layer manager with SVG. - Out-of-bounds read with cached style data and pseudo-elements. - Same-origin policy bypass with iframes through page reloads. - Domain hijacking through AppCache fallback. - Buffer overflow viewing certificates with an extremely long OID. - Spoofing following page navigation with data: protocol and modal alerts. - CSP information leak with frame-ancestors containing paths. - Elliptic curve point addition error when using mixed Jacobian-affine coordinates. - CSP containing sandbox improperly applied. - Self-XSS XUL injection in about:webrtc. - DOS attack through long username in URL. - Sandboxed about:srcdoc iframes do not inherit CSP directives. - Failure to enable HSTS when two STS headers are sent for a connection. - Response header name interning leaks across origins. - Memory safety bugs.

Successful exploitation of these vulnerabilities will allow remote attackers to run arbitrary code, obtain sensitive information, cause denial of service, conduct cross-site scripting (XSS) attack, spoofing attack and bypass existing memory protections.

Affected Versions:
Mozilla Firefox version before 55.0 on MAC OS X.

Upgrade to Mozilla Firefox version 55.0 or later.

Solution Type:
Vendor Patch

Detection Type:

Vulnerability management is the process in which vulnerabilities in IT are identified and the risks of these vulnerabilities are evaluated. This evaluation leads to correcting the vulnerabilities and removing the risk or a formal risk acceptance by the management of an organization. The term vulnerability management is often confused with vulnerability scanning. Despite the fact both are related, there is an important difference between the two. Vulnerability scanning consists of using a computer program to identify vulnerabilities in networks, computer infrastructure or applications. Vulnerability management is the process surrounding vulnerability scanning, also taking into account other aspects such as risk acceptance, remediation etc. Source: "Implementing a Vulnerability Management Process".
