NewStart CGSL MAIN 6.01 : thunderbird Multiple Vulnerabilities (NS-SA-2020-0036)
critical Nessus Plugin ID 138776
Language:
Synopsis
The remote machine is affected by multiple vulnerabilities.Description
The remote NewStart CGSL host, running version MAIN 6.01, has thunderbird packages installed that are affected by multiple vulnerabilities:- By encoding Unicode whitespace characters within the From email header, an attacker can spoof the sender email address that Thunderbird displays. This vulnerability affects Thunderbird < 68.8.0.
(CVE-2020-12397)
- Under certain conditions, when running the nsDocShell destructor, a race condition can cause a use-after-free.
We are aware of targeted attacks in the wild abusing this flaw. This vulnerability affects Thunderbird < 68.7.0, Firefox < 74.0.1, and Firefox ESR < 68.6.1.
(CVE-2020-6819)
- Under certain conditions, when handling a ReadableStream, a race condition can cause a use-after- free. We are aware of targeted attacks in the wild abusing this flaw. This vulnerability affects Thunderbird < 68.7.0, Firefox < 74.0.1, and Firefox ESR < 68.6.1. (CVE-2020-6820)
- When reading from areas partially or fully outside the source resource with WebGL's copyTexSubImage method, the specification requires the returned values be zero. Previously, this memory was uninitialized, leading to potentially sensitive data disclosure. This vulnerability affects Thunderbird < 68.7.0, Firefox ESR < 68.7, and Firefox < 75. (CVE-2020-6821)
- On 32-bit builds, an out of bounds write could have occurred when processing an image larger than 4 GB in GMPDecodeData. It is possible that with enough effort this could have been exploited to run arbitrary code. This vulnerability affects Thunderbird < 68.7.0, Firefox ESR < 68.7, and Firefox < 75.
(CVE-2020-6822)
- Mozilla developers and community members Tyson Smith and Christian Holler reported memory safety bugs present in Firefox 74 and Firefox ESR 68.6. Some of these bugs showed evidence of memory corruption and we presume that with enough effort some of these could have been exploited to run arbitrary code. This vulnerability affects Thunderbird < 68.7.0, Firefox ESR < 68.7, and Firefox < 75. (CVE-2020-6825)
- A race condition when running shutdown code for Web Worker led to a use-after-free vulnerability. This resulted in a potentially exploitable crash. This vulnerability affects Firefox ESR < 68.8, Firefox < 76, and Thunderbird < 68.8.0. (CVE-2020-12387)
- A buffer overflow could occur when parsing and validating SCTP chunks in WebRTC. This could have led to memory corruption and a potentially exploitable crash.
This vulnerability affects Firefox ESR < 68.8, Firefox < 76, and Thunderbird < 68.8.0. (CVE-2020-6831)
- The 'Copy as cURL' feature of Devtools' network tab did not properly escape the HTTP POST data of a request, which can be controlled by the website. If a user used the 'Copy as cURL' feature and pasted the command into a terminal, it could have resulted in the disclosure of local files. This vulnerability affects Firefox ESR < 68.8, Firefox < 76, and Thunderbird < 68.8.0.
(CVE-2020-12392)
- Mozilla developers and community members reported memory safety bugs present in Firefox 75 and Firefox ESR 68.7.
Some of these bugs showed evidence of memory corruption and we presume that with enough effort some of these could have been exploited to run arbitrary code. This vulnerability affects Firefox ESR < 68.8, Firefox < 76, and Thunderbird < 68.8.0. (CVE-2020-12395)
Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.
