Summary: firefox vulnerabilities

Details: 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 via application crash or opening new tabs, escape the sandbox, bypass same-origin restrictions, obtain sensitive information, confuse the user with misleading permission requests, or execute arbitrary code. (CVE-2018-5125, CVE-2018-5126, CVE-2018-5127, CVE-2018-5128, CVE-2018-5129, CVE-2018-5130, CVE-2018-5136, CVE-2018-5137, CVE-2018-5140, CVE-2018-5141, CVE-2018-5142) It was discovered that the fetch() API could incorrectly return cached copies of no-store/no-cache resources in some circumstances. A local attacker could potentially exploit this to obtain sensitive information in environments where multiple users share a common profile. (CVE-2018-5131) Multiple security issues were discovered with WebExtensions. If a user were tricked in to installing a specially crafted extension, an attacker could potentially exploit these to obtain sensitive information or bypass security restrictions. (CVE-2018-5132, CVE-2018-5134, CVE-2018-5135) It was discovered that the value of app.support.baseURL is not sanitized properly. If a malicious local application were to set this to a specially crafted value, an attacker could potentially exploit this to execute arbitrary code. (CVE-2018-5133) It was discovered that javascript: URLs with embedded tab characters could be pasted in to the addressbar. If a user were tricked in to copying a specially crafted URL in to the addressbar, an attacker could exploit this to conduct cross-site scripting (XSS) attacks. (CVE-2018-5143)
