5. A buffer overflow vulnerability in WebGL can be exploited remotely to cause a denial of service;
6. Origin confusion vulnerability related to reloading isolated data:text/html URL can be exploited remotely to execute a cross-site scripting (XSS) attack;
7. A use-after-free vulnerability during focus handling can be exploited remotely to cause a denial of service;
8. A use-after-free vulnerability in text input selection can be exploited remotely to cause a denial of service;
9. A use-after-free vulnerability in frame selection can be exploited remotely to cause a denial of service;
10. A use-after-free vulnerability in nsAutoPtr during XSLT processing can be exploited remotely to cause a denial of service;
11. A use-after-free vulnerability in txExecutionState destructor related to XSLT processing can be exploited remotely to cause a denial of service;
12. Use-after-free vulnerability in nsTArray Length() during XSLT processing can be exploited remotely to cause a denial of service;
13. Use-after-free vulnerability with selection during scroll events can be exploited remotely to cause a denial of service;
14. Use-after-free vulnerability during style changes when manipulating DOM elements can be exploited remotely to cause a denial of service;
15. Memory corruption vulnerability with accessibility and DOM manipulation can be exploited remotely to cause a denial of service;
16. An out-of-bounds write vulnerability during BinHex decoding can be exploited remotely to cause a denial of service;
17. A buffer overflow vulnerability while parsing application/http-index-format content can be exploited remotely to cause a denial of service or obtain a sensitive information;
18. An out-of-bounds read vulnerability when HTTP/2 DATA frames are sent with incorrect data can be exploited remotely to cause a denial of service;
19. An out-of-bounds read vulnerability during glyph processing can be exploited remotely to cause denial of service or obtain a sensitive information;
20. An out-of-bounds read vulnerability while processing SVG content in ConvolvePixel and during glyph processing can be exploited remotely to cause a denial of service or obtain a sensitive information;
21. Multiple out-of-bounds read vulnerabilities in the Libevent library can be exploited remotely to cause a denial of service;
22. Multiple potential buffer overflows in flex-generated code can be exploited remotely possibly to cause a denial of service;
23. Multiple memory corruption vulnerabilities, which occur because of memory safety bugs, can be exploited remotely to execute arbitrary code;
24. A potential memory corruption occurring while drawing Skia content outside the bounds of a clipping region can be exploited remotely possibly to cause a denial of service;
25. An improper sandbox escape handling can be exploited remotely through file picker via relative paths to bypass security restrictions and gain privileges (get read only access to the local file system);
26. An unknown vulnerability can be exploited remotely via the user interaction on the adressbar and the onblur event to spoof adressbar;
27. An improper handling of layouts and manipulations of bidirectional unicode text combined with CSS animations can be exploited remotely to cause a denial of service;
28. A vulnerability related to parsing application/http-index-format content can be exploited remotely possibly to cause a denial of service or execute arbitrary code;
29. An improper DRBG number generation in NSS (Network Security Services) library can be exploited remotely possibly to cause a denial of service or execute arbitrary code.

Impacts

• ACE

Arbitrary code execution. Exploitation of vulnerabilities with this impact can lead to executing by abuser any code or commands at vulnerable machine or process.

• OSI

Obtain sensitive information. Exploitation of vulnerabilities with this impact can lead to capturing by abuser information, critical for user or system.

• DoS

Denial of service. Exploitation of vulnerabilities with this impact can lead to loss of system availability or critical functional fault.

• SB
