  - Use after free in ANGLE in Google Chrome prior to     81.0.4044.122 allowed a remote attacker to potentially     exploit heap corruption via a crafted HTML page.
    (CVE-2020-6463)

The remote NewStart CGSL host, running version MAIN 6.02, has thunderbird packages installed that are affected by multiple vulnerabilities:

  - Due to confusion about ValueTags on JavaScript Objects, an object may pass through the type barrier,     resulting in memory corruption and a potentially exploitable crash. *Note: this issue only affects Firefox     on ARM64 platforms.* This vulnerability affects Firefox ESR < 68.10, Firefox < 78, and Thunderbird <     68.10.0. (CVE-2020-12417)

  - Manipulating individual parts of a URL object could have caused an out-of-bounds read, leaking process     memory to malicious JavaScript. This vulnerability affects Firefox ESR < 68.10, Firefox < 78, and     Thunderbird < 68.10.0. (CVE-2020-12418)

  - When processing callbacks that occurred during window flushing in the parent process, the associated     window may die; causing a use-after-free condition. This could have led to memory corruption and a     potentially exploitable crash. This vulnerability affects Firefox ESR < 68.10, Firefox < 78, and     Thunderbird < 68.10.0. (CVE-2020-12419)

  - When trying to connect to a STUN server, a race condition could have caused a use-after-free of a pointer,     leading to memory corruption and a potentially exploitable crash. This vulnerability affects Firefox ESR <     68.10, Firefox < 78, and Thunderbird < 68.10.0. (CVE-2020-12420)

  - When performing add-on updates, certificate chains terminating in non-built-in-roots were rejected (even     if they were legitimately added by an administrator.) This could have caused add-ons to become out-of-date     silently without notification to the user. This vulnerability affects Firefox ESR < 68.10, Firefox < 78,     and Thunderbird < 68.10.0. (CVE-2020-12421)

  - Use after free in ANGLE in Google Chrome prior to 81.0.4044.122 allowed a remote attacker to potentially     exploit heap corruption via a crafted HTML page. (CVE-2020-6463)

  - Inappropriate implementation in WebRTC in Google Chrome prior to 84.0.4147.89 allowed an attacker in a     privileged network position to potentially exploit heap corruption via a crafted SCTP stream.
    (CVE-2020-6514)

  - By observing the stack trace for JavaScript errors in web workers, it was possible to leak the result of a     cross-origin redirect. This applied only to content that can be parsed as script. This vulnerability     affects Firefox < 79, Firefox ESR < 68.11, Firefox ESR < 78.1, Thunderbird < 68.11, and Thunderbird <     78.1. (CVE-2020-15652)

  - Mozilla developers and community members reported memory safety bugs present in Firefox 78 and Firefox ESR     78.0. 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 < 79, Firefox     ESR < 68.11, Firefox ESR < 78.1, Thunderbird < 68.11, and Thunderbird < 78.1. (CVE-2020-15659)

  - By holding a reference to the eval() function from an about:blank window, a malicious webpage could have     gained access to the InstallTrigger object which would allow them to prompt the user to install an     extension. Combined with user confusion, this could result in an unintended or malicious extension being     installed. This vulnerability affects Firefox < 80, Thunderbird < 78.2, Thunderbird < 68.12, Firefox ESR <     68.12, Firefox ESR < 78.2, and Firefox for Android < 80. (CVE-2020-15664)

  - When aborting an operation, such as a fetch, an abort signal may be deleted while alerting the objects to     be notified. This results in a use-after-free and we presume that with enough effort it could have been     exploited to run arbitrary code. This vulnerability affects Firefox ESR < 68.12 and Thunderbird < 68.12.
    (CVE-2020-15669)

  - If an attacker intercepts Thunderbird's initial attempt to perform automatic account setup using the     Microsoft Exchange autodiscovery mechanism, and the attacker sends a crafted response, then Thunderbird     sends username and password over https to a server controlled by the attacker. This vulnerability affects     Thunderbird < 68.10.0. (CVE-2020-15646)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

The remote SUSE Linux SLES11 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2020:14456-1 advisory.

  - By observing the stack trace for JavaScript errors in web workers, it was possible to leak the result of a     cross-origin redirect. This applied only to content that can be parsed as script. This vulnerability     affects Firefox < 79, Firefox ESR < 68.11, Firefox ESR < 78.1, Thunderbird < 68.11, and Thunderbird <     78.1. (CVE-2020-15652)

  - An iframe sandbox element with the allow-popups flag could be bypassed when using noopener links. This     could have led to security issues for websites relying on sandbox configurations that allowed popups and     hosted arbitrary content. This vulnerability affects Firefox ESR < 78.1, Firefox < 79, and Thunderbird <     78.1. (CVE-2020-15653)

  - When in an endless loop, a website specifying a custom cursor using CSS could make it look like the user     is interacting with the user interface, when they are not. This could lead to a perceived broken state,     especially when interactions with existing browser dialogs and warnings do not work. This vulnerability     affects Firefox ESR < 78.1, Firefox < 79, and Thunderbird < 78.1. (CVE-2020-15654)

  - A redirected HTTP request which is observed or modified through a web extension could bypass existing CORS     checks, leading to potential disclosure of cross-origin information. This vulnerability affects Firefox     ESR < 78.1, Firefox < 79, and Thunderbird < 78.1. (CVE-2020-15655)

  - JIT optimizations involving the Javascript arguments object could confuse later optimizations. This risk     was already mitigated by various precautions in the code, resulting in this bug rated at only moderate     severity. This vulnerability affects Firefox ESR < 78.1, Firefox < 79, and Thunderbird < 78.1.
    (CVE-2020-15656)

  - Firefox could be made to load attacker-supplied DLL files from the installation directory. This required     an attacker that is already capable of placing files in the installation directory. *Note: This issue only     affected Windows operating systems. Other operating systems are unaffected.*. This vulnerability affects     Firefox ESR < 78.1, Firefox < 79, and Thunderbird < 78.1. (CVE-2020-15657)

  - The code for downloading files did not properly take care of special characters, which led to an attacker     being able to cut off the file ending at an earlier position, leading to a different file type being     downloaded than shown in the dialog. This vulnerability affects Firefox ESR < 78.1, Firefox < 79, and     Thunderbird < 78.1. (CVE-2020-15658)

  - Mozilla developers and community members reported memory safety bugs present in Firefox 78 and Firefox ESR     78.0. 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 < 79, Firefox     ESR < 68.11, Firefox ESR < 78.1, Thunderbird < 68.11, and Thunderbird < 78.1. (CVE-2020-15659)

  - Use after free in ANGLE in Google Chrome prior to 81.0.4044.122 allowed a remote attacker to potentially     exploit heap corruption via a crafted HTML page. (CVE-2020-6463)

  - Inappropriate implementation in WebRTC in Google Chrome prior to 84.0.4147.89 allowed an attacker in a     privileged network position to potentially exploit heap corruption via a crafted SCTP stream.
    (CVE-2020-6514)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Multiple security issues have been found in the Mozilla Firefox web browser, which could potentially result in the execution of arbitrary code or an information leak.
