Mozilla Firefox ESR < 52.4 Multiple Vulnerabilities

High Nessus Network Monitor Plugin ID 700331

Synopsis

The remote host has a web browser installed that is vulnerable to multiple attack vectors.

Description

Versions of Mozilla Firefox ESR earlier than 52.4 are unpatched for the following vulnerabilities :

- A flaw exists in 'js/src/vm/StructuredClone.cpp' that is triggered when handling structured clone reads. This may allow a context-dependent attacker to corrupt memory and potentially execute arbitrary code.
- An unspecified flaw exists that is triggered as certain input is not properly validated. This may allow a context-dependent attacker to corrupt memory and potentially execute arbitrary code. No further details have been provided by the vendor.
- A flaw exists in 'editor/libeditor/HTMLEditor.cpp' that is triggered when handling root elements in the editor. This may allow a context-dependent attacker to corrupt memory and potentially execute arbitrary code.
- A flaw exists in 'dom/media/GraphDriver.cpp' that is triggered when handling errors. This may allow a context-dependent attacker to corrupt memory and potentially execute arbitrary code.
- An overflow condition exists in the 'hnj_hyphen_hyphword()' function in 'hyphen.c' that is triggered as certain input is not properly validated. This may allow a context-dependent attacker to cause a buffer overflow and potentially execute arbitrary code within a process linked against the library.
- A flaw exists in the 'EditorBase::FinalizeSelection()' function in 'editor/libeditor/EditorBase.cpp' that is triggered as certain input is not properly validated. This may allow a context-dependent attacker to corrupt memory and potentially execute arbitrary code.
- A flaw exists in the 'DocAccessible::DoARIAOwnsRelocation()' function in 'accessible/generic/DocAccessible.cpp' that is triggered as certain input is not properly validated. This may allow a context-dependent attacker to corrupt memory and potentially execute arbitrary code.
- A use-after-free condition exists in the Fetch API related to missing thread safety. This may allow a context-dependent attacker to dereference already freed memory and potentially execute arbitrary code.
- A use-after-free error exists in 'accessible/generic/DocAccessible.cpp' that is triggered when manipulating Accessible Rich Internet Applications (ARIA) elements. This may allow a context-dependent attacker to dereference already freed memory and potentially execute arbitrary code.
- A use-after-free error exists in design mode that is triggered when objects are resized. This may allow a context-dependent attacker to dereference already freed memory and potentially execute arbitrary code.
- A use-after-free error exists in the 'ssl3_HandleCertificateVerify()' function in 'lib/ssl/ssl3con.c' that is triggered when handling handshake hashes during TLS '1.2' exchanges. This may allow a context-dependent attacker to dereference already freed memory and potentially execute arbitrary code.
- A flaw exists in the PendingLookup class in 'toolkit/components/downloads/ApplicationReputation.cpp' that is triggered when handling downloads encoded with data: and blob: URL elements. This may allow a context-dependent attacker to bypass the phishing and malware protection feature.
- A flaw exists in the 'MacOSFontEntry::ReadCMAP()' function in 'gfx/thebes/gfxMacPlatformFontList.mm' that is triggered as certain tibetan and arabic unicode characters are displayed as whitespace in combination with macOS fonts. With a specially crafted IDN domain, a context-dependent attacker can spoof a valid URL and conduct phishing attacks.
- A flaw exists in the 'nsDocument::InitCSP()' function in 'dom/base/nsDocument.cpp' that is triggered as the sandbox directive does not create unique origin. This may result in incorrect enforcement of the content security policy (CSP).
- An unspecified flaw exists that is triggered when drawing and validating elements with the ANGLE graphics library. This may allow a context-dependent attacker to cause a buffer overflow, potentially allowing the execution of arbitrary code.

Solution

Upgrade to Firefox ESR version 52.4 or later.
