    descriptionThe version of Firefox installed on the remote macOS or Mac OS X host is prior to 77.0. It is, therefore, affected by multiple vulnerabilities as referenced in the mfsa2020-20 advisory. - NSS has shown timing differences when performing DSA signatures, which was exploitable and could eventually leak private keys. (CVE-2020-12399) - When browsing a malicious page, a race condition in our SharedWorkerService could occur and lead to a potentially exploitable crash. (CVE-2020-12405) - Mozilla Developer Iain Ireland discovered a missing type check during unboxed objects removal, resulting in a crash. We presume that with enough effort that it could be exploited to run arbitrary code. (CVE-2020-12406) - Mozilla Developer Nicolas Silva found that when using WebRender, Firefox would under certain conditions leak arbitrary GPU memory to the visible screen. The leaked memory content was visible to the user, but not observable from web content. (CVE-2020-12407) - When browsing a document hosted on an IP address, an attacker could insert certain characters to flip domain and path information in the address bar. (CVE-2020-12408) - Mozilla developers Tom Tung and Karl Tomlinson reported memory safety bugs present in Firefox 76 and Firefox ESR 68.8. 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. (CVE-2020-12409) - Mozilla developers :Gijs (he/him), Randell Jesup reported memory safety bugs present in Firefox 76. 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. (CVE-2020-12411) Note that Nessus has not tested for this issue but has instead relied only on the application

    descriptionMultiple security issues were discovered in Firefox. If a user were tricked in to opening a specially crafted website, an attacker could potentially exploit these to cause a denial of service, spoof the addressbar, or execute arbitrary code. (CVE-2020-12405, CVE-2020-12406, CVE-2020-12407, CVE-2020-12408, CVE-2020-12409, CVE-2020-12410, CVE-2020-12411) It was discovered that NSS showed timing differences when performing DSA signatures. An attacker could potentially exploit this to obtain private keys using a timing attack. (CVE-2020-12399). Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
