USN-3918-1: Firefox vulnerabilities<\/p>\n
A security issue affects these releases of Ubuntu and its derivatives:<\/p>\n
Several security issues were fixed in Firefox.<\/p>\n
Multiple security issues were discovered in Firefox. If a user were
\ntricked in to opening a specially crafted website, an attacker could
\npotentially exploit these to cause a denial of service via application
\ncrash, denial of service via successive FTP authorization prompts or modal
\nalerts, trick the user with confusing permission request prompts, obtain
\nsensitive information, conduct social engineering attacks, or execute
\narbitrary code. (CVE-2019-9788, CVE-2019-9789, CVE-2019-9790,
\nCVE-2019-9791, CVE-2019-9792, CVE-2019-9795, CVE-2019-9796, CVE-2019-9797,

\nCVE-2019-9808, CVE-2019-9809)<\/p>\n
A mechanism was discovered that removes some bounds checking for string,
\narray, or typed array accesses if Spectre mitigations have been disabled.
\nIf a user were tricked in to opening a specially crafted website with
\nSpectre mitigations disabled, an attacker could potentially exploit this
\nto cause a denial of service, or execute arbitrary code. (CVE-2019-9793)<\/p>\n
It was discovered that Upgrade-Insecure-Requests was incorrectly enforced
\nfor same-origin navigation. An attacker could potentially exploit this to
\nconduct man-in-the-middle (MITM) attacks. (CVE-2019-9803)<\/p>\n
