Vulnerability Insight:
Multiple flaws exist due to:
- An use-after-free in SMIL animation functions,
- An use-after-free during transaction processing in the editor,
- An uut-of-bounds write with malicious font in Graphite 2,
- An Out-of-bounds write in Base64 encoding in NSS,
- The buffer overflow in WebGL,
- The origin confusion when reloading isolated data:text/html URL,
- An use-after-free during focus handling,
- An use-after-free in text input selection,
- An use-after-free in frame selection,
- An use-after-free in nsAutoPtr during XSLT processing,
- An use-after-free in nsTArray Length() during XSLT processing,
- An use-after-free in txExecutionState destructor during XSLT processing,
- An use-after-free with selection during scroll events,
- An use-after-free during style changes,
- The memory corruption with accessibility and DOM manipulation,
- The out-of-bounds write during BinHex decoding,
- The buffer overflow while parsing application/http-index-format content,
- An out-of-bounds read when HTTP/2 DATA frames are sent with incorrect data,
- An out-of-bounds read during glyph processing,
- An out-of-bounds read in ConvolvePixel,
- An out-of-bounds write in ClearKeyDecryptor,
- The vulnerabilities in Libevent library,
- The sandbox escape allowing file system read access through file picker,
- The sandbox escape through internal feed reader APIs,
- The sandbox escape allowing local file system access,
- The Potential Buffer overflow in flex-generated code,
- An uninitialized values used while parsing application/http-index-format content,
- The crash during bidirectional unicode manipulation with animation,
- An addressbar spoofing using javascript: URI on Firefox for Android,
- An addressbar spoofing with onblur event,
- The DRBG flaw in NSS,
- The memory corruption when drawing Skia content,
- The addressbar spoofing during scrolling with editable content on Firefox for Android,
- The HTML injection into RSS Reader feed preview page through TITLE element,
- The drag and drop of javascript: URLs can allow for self-XSS,
- An incorrect ownership model for Private Browsing information and
- The memory safety bugs fixed in Firefox 53 and Firefox ESR 52.1.
Vulnerability Impact:
Successful exploitation will allow remote
attackers to execute arbitrary code, to delete arbitrary files by leveraging
certain local file execution, to obtain sensitive information, and to cause
a denial of service.
Affected Software/OS:
Mozilla Firefox version before
53.0 on Mac OS X.
Solution:
Upgrade to Mozilla Firefox version 53.0
or later.
CVSS Score:
10.0
