firefox vulnerabilities
A security issue affects these releases of Ubuntu and its derivatives:
Firefox could be made to crash or run programs as your login if it opened a malicious website.
Software Description
Multiple 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 URL or other browser chrome, obtain sensitive information, bypass Content Security Policy (CSP) protections, or execute arbitrary code. (CVE-2019-20503, CVE-2020-6805, CVE-2020-6806, CVE-2020-6807, CVE-2020-6808, CVE-2020-6810, CVE-2020-6812, CVE-2020-6813, CVE-2020-6814, CVE-2020-6815)
It was discovered that Web Extensions with the all-url permission could access local files. If a user were tricked in to installing a specially crafted extension, an attacker could potentially exploit this to obtain sensitive information. (CVE-2020-6809)
It was discovered that the Devtools’ ‘Copy as cURL’ feature did not fully escape website-controlled data. If a user were tricked in to using the ‘Copy as cURL’ feature to copy and paste a command with specially crafted data in to a terminal, an attacker could potentially exploit this to execute arbitrary commands via command injection. (CVE-2020-6811)
