Multiple serious vulnerabilities have been found in Mozilla Thunderbird. Malicious users can exploit these vulnerabilities to obtain sensitive information, run arbitrary code, cause a denial of service and spoofing user interface.

Below is a complete list of vulnerabilities

1. Memory corruption vulnerability in asm.js can be exploited remotely to bypass of ASLR and DEP protections leading to a denial of service;
2. Memory corruption vulnerability in triggerable web content can be exploited remotely to cause a denial of service;
3. Use-after-free vulnerability, which can occur when events are fired, after their destroying in the FontFace objects can be exploited remotely to cause a denial of service;
4. Use-after-free vulnerability, which can occur when manipulating ranges in selections can be exploited remotely to cause a denial of service;
5. Pixel and history stealing vulnerability in the SVG filters can be exploited remotely to obtain sensitive information;
6. Memory corruption vulnerability in the JavaScript garbage collection can be exploited remotely to cause a denial of service;
7. Cross-origin reading vulnerability in the CORS can be exploited remotely to obtain sensitive information;
8. Usage of uninitialized values for ports in FTP connections can be exploited remotely to cause a denial of service;
9. Memory corruption vulnerability can be exploited remotely to run arbitrary code;
10. Memory corruption vulnerability caused by out of bounds access in Element::DescribeAttribute() can be exploited remotely possibly to run arbitrary code or cause a denial of service;
11. Use-after-free vulnerability, which can occur while adding the range to an incorrect root object in the DOM can be exploited remotely to cause a denial of service;
12. A segmentation fault vulnerability in the Skia graphics library can be exploited remotely to cause a denial of service;
13. Use-after-free vulnerability in the Buffer Storage in libGLES can be exploited remotely to cause a denial of service;
14. Buffer overflow read in SVG filters can be exploited remotely leading to loss of some information, contained in overwritten files;
15. A segmentation fault vulnerability, which can occur during bidirectional operations can be exploited remotely to cause a denial of service;
16. Incorrect local default directory chosen by File picker can be exploited remotely to obtain sensitive information;
17. A premature release of a networking event listener in HttpChannel can be exploited remotely to cause a denial of service;
18. Out of bounds read when parsing HTTP digest authorization responses can be exploited remotely to cause denial of service or obtain sensitive information;
19. Repeated authentication prompts can be exploited remotely to cause a denial of service;
20. An unknown vulnerability which can occur if popup windows are enabled can be exploited remotely leading to changes in user interface;
21. Incorrect protocol using in a series within a single hyperlink in the view-source can be exploited remotely to cause a denial of service.

NB: This vulnerability have no public CVSS rating so rating can be changed by the time.NB: At this moment Mozilla just reserved CVE numbers for this vulnerabilities. Information can be changed soon.
