[ASA-201810-14] firefox: multiple issues
Arch Linux Security Advisory ASA-201810-14 ========================================== Severity: Critical Date : 2018-10-24 CVE-ID : CVE-2018-12388 CVE-2018-12390 CVE-2018-12392 CVE-2018-12395 CVE-2018-12396 CVE-2018-12397 CVE-2018-12398 CVE-2018-12399 CVE-2018-12401 CVE-2018-12402 CVE-2018-12403 Package : firefox Type : multiple issues Remote : Yes Link : https://security.archlinux.org/AVG-787 Summary ======= The package firefox before version 63.0-1 is vulnerable to multiple issues including arbitrary code execution, access restriction bypass, privilege escalation, content spoofing, denial of service and information disclosure. Resolution ========== Upgrade to 63.0-1. # pacman -Syu "firefox>=63.0-1" The problems have been fixed upstream in version 63.0. Workaround ========== None. Description =========== - CVE-2018-12388 (arbitrary code execution) Several memory safety bugs have been found in Firefox versions prior to 63.0. Some of these bugs showed evidence of memory corruption and Mozilla engineers presume that with enough effort some of these could be exploited to run arbitrary code. - CVE-2018-12390 (arbitrary code execution) Several memory safety bugs have been found in Firefox versions prior to 63.0. Some of these bugs showed evidence of memory corruption and Mozilla engineers presume that with enough effort some of these could be exploited to run arbitrary code. - CVE-2018-12392 (arbitrary code execution) A security issue has been found in Firefox versions prior to 63.0. When manipulating user events in nested loops while opening a document through script, it is possible to trigger a potentially exploitable crash due to poor event handling. - CVE-2018-12395 (access restriction bypass) A security issue has been found in Firefox versions prior to 63.0, where by rewriting the Host request headers using the webRequest API, a WebExtension can bypass domain restrictions through domain fronting. This would allow access to domains that share a host that are otherwise restricted. - CVE-2018-12396 (privilege escalation) A security issue has been found in Firefox versions prior to 63.0, where a WebExtension can run content scripts in disallowed contexts following navigation or other events. This allows for potential privilege escalation by the WebExtension on sites where content scripts should not be run. - CVE-2018-12397 (access restriction bypass) A security issue has been found in Firefox versions prior to 63.0, where a WebExtension can request access to local files without the warning prompt stating that the extension will "Access your data for all websites" being displayed to the user. This allows extensions to run content scripts in local pages without permission warnings when a local file is opened. - CVE-2018-12398 (access restriction bypass) A security issue has been found in Firefox versions prior to 63.0, where it is possible to inject stylesheets and bypass Content Security Policy (CSP) by using the reflected URL in some special resource URIs, such as chrome:. - CVE-2018-12399 (content spoofing) A security issue has been found in Firefox versions prior to 63.0, where when a new protocol handler is registered, the API accepts a title argument which can be used to mislead users about which domain is registering the new protocol. This may result in the user approving a protocol handler that they otherwise would not have. - CVE-2018-12401 (denial of service) A security issue has been found in Firefox versions prior to 63.0, where some special resource URIs will cause a non-exploitable crash if loaded with optional parameters following a '?' in the parsed string. This could lead to denial of service (DOS) attacks. - CVE-2018-12402 (information disclosure) A security issue has been found in Firefox versions prior to 63.0, where SameSite cookies are sent on cross-origin requests when the "Save Page As..." menu item is selected to save a page, violating cookie policy. This can result in saving the wrong version of resources based on those cookies. - CVE-2018-12403 (content spoofing) A security issue has been found in Firefox versions prior to 63.0, where if a site is loaded over a HTTPS connection but loads a favicon resource over HTTP, the mixed content warning is not displayed to users. Impact ====== A remote attacker can bypass domain restrictions, bypass various warnings, crash the browser, escalate privileges and execute arbitrary code on the affected host.
