Arch Linux Security Advisory ASA-201708-3 ========================================= Severity: Critical Date : 2017-08-10 CVE-ID : CVE-2017-7753 CVE-2017-7779 CVE-2017-7780 CVE-2017-7781 CVE-2017-7783 CVE-2017-7784 CVE-2017-7785 CVE-2017-7786 CVE-2017-7787 CVE-2017-7788 CVE-2017-7789 CVE-2017-7791 CVE-2017-7792 CVE-2017-7794 CVE-2017-7797 CVE-2017-7798 CVE-2017-7799 CVE-2017-7800 CVE-2017-7801 CVE-2017-7802 CVE-2017-7803 CVE-2017-7806 CVE-2017-7807 CVE-2017-7808 CVE-2017-7809 Package : firefox Type : multiple issues Remote : Yes Link : https://security.archlinux.org/AVG-375 Summary ======= The package firefox before version 55.0-1 is vulnerable to multiple issues including arbitrary code execution, content spoofing, information disclosure, same-origin policy bypass, access restriction bypass, cross-site scripting, incorrect calculation, sandbox escape and denial of service. Resolution ========== Upgrade to 55.0-1. # pacman -Syu "firefox>=55.0-1" The problems have been fixed upstream in version 55.0. Workaround ========== None. Description =========== - CVE-2017-7753 (information disclosure) An out-of-bounds read has been found in Firefox < 55.0, when applying style rules to pseudo-elements, such as ::first-line, using cached style data. - CVE-2017-7779 (arbitrary code execution) Several memory safety bugs have been found in Firefox < 55.0. Some of these bugs showed evidence of memory corruption and we presume that with enough effort that some of these could be exploited to run arbitrary code. - CVE-2017-7780 (arbitrary code execution) Several memory safety bugs have been found in Firefox < 55.0. Some of these bugs showed evidence of memory corruption and we presume that with enough effort that some of these could be exploited to run arbitrary code. - CVE-2017-7781 (incorrect calculation) An elliptic curve point addition error has been found in Firefox < 55.0. An error occurs in the elliptic curve point addition algorithm that uses mixed Jacobian-affine coordinates where it can yield a result POINT_AT_INFINITY when it should not. A man-in-the-middle attacker could use this to interfere with a connection, resulting in an attacked party computing an incorrect shared secret. - CVE-2017-7783 (denial of service) A denial of service has been found in Firefox < 55.0. If a long user name is used in a username/password combination in a site URL (such as http://UserName:Password@example.com), the resulting modal prompt will hang in a non-responsive state or crash, causing a denial of service. - CVE-2017-7784 (arbitrary code execution) A use-after-free issue has been found in Firefox < 55.0, when reading an image observer during frame reconstruction after the observer has been freed. This results in a potentially exploitable crash. - CVE-2017-7785 (arbitrary code execution) A buffer overflow has been found in Firefox < 55.0, when manipulating Accessible Rich Internet Applications (ARIA) attributes within the DOM. This results in a potentially exploitable crash. - CVE-2017-7786 (arbitrary code execution) A buffer overflow has been found in Firefox < 55.0, when the image renderer attempts to paint non-displayable SVG elements. This results in a potentially exploitable crash. - CVE-2017-7787 (same-origin policy bypass) Same-origin policy protections can be bypassed in Firefox < 55.0, on pages with embedded iframes during page reloads, allowing the iframes to access content on the top level page and leading to information disclosure. - CVE-2017-7788 (access restriction bypass) A security issue has been found in Firefox < 55.0. When an iframe has a sandbox attribute and its content is specified using srcdoc, that content does not inherit the containing page's Content Security Policy (CSP) as it should unless the sandbox attribute included allow-same- origin. - CVE-2017-7789 (access restriction bypass) A security issue has been found in Firefox < 55.0. If a server sends two Strict-Transport-Security (STS) headers for a single connection, they will be rejected as invalid and HTTP Strict Transport Security (HSTS) will not be enabled for the connection. - CVE-2017-7791 (content spoofing) A content spoofing issue has been found in Firefox < 55.0. On pages containing an iframe, the data: protocol can be used to create a modal alert that will render over arbitrary domains following page navigation, spoofing of the origin of the modal alert from the iframe content. - CVE-2017-7792 (arbitrary code execution) A buffer overflow has been found in Firefox < 55.0, when viewing a certificate in the certificate manager if the certificate has an extremely long object identifier (OID). This results in a potentially exploitable crash. - CVE-2017-7794 (sandbox escape) A security issue has been found in Firefox < 55.0. On Linux systems, if the content process is compromised, the sandbox broker will allow files to be truncated even though the sandbox explicitly only has read access to the local file system and no write permissions. - CVE-2017-7797 (access restriction bypass) A security issue has been found in Firefox <55.0. Response header name interning does not have same-origin protections and these headers are stored in a global registry. This allows stored header names to be available cross-origin. - CVE-2017-7798 (arbitrary code execution) A XUL injection has been found in Firefox < 55.0, in the style editor in devtools. The Developer Tools feature suffers from a XUL injection vulnerability due to improper sanitization of the web page source code. In the worst case, this could allow arbitrary code execution when opening a malicious page with the style editor tool. - CVE-2017-7799 (cross-site scripting) A security issue has been found in Firefox < 55.0. JavaScript in the about:webrtc page is not sanitized properly being being assigned to innerHTML. Data on this page is supplied by WebRTC usage and is not under third-party control, making this difficult to exploit, but the vulnerability could possibly be used for a cross-site scripting (XSS) attack. - CVE-2017-7800 (arbitrary code execution) A use-after-free issue has been found in Firefox < 55.0, in WebSockets, when the object holding the connection is freed before the disconnection operation is finished. This results in an exploitable crash. - CVE-2017-7801 (arbitrary code execution) A use-after-free issue has been found in Firefox < 55.0, while re- computing layout for a marquee element during window resizing where the updated style object is freed while still in use. This results in a potentially exploitable crash. - CVE-2017-7802 (arbitrary code execution) A use-after-free vulnerability has been found in Firefox < 55.0, when manipulating the DOM during the resize event of an image element. If these elements have been freed due to a lack of strong references, a potentially exploitable crash may occur when the freed elements are accessed. - CVE-2017-7803 (access restriction bypass) A security issue has been found in Firefox < 55.0. When a page’s content security policy (CSP) header contains a sandbox directive, other directives are ignored. This results in the incorrect enforcement of CSP. - CVE-2017-7806 (arbitrary code execution) A use-after-free vulnerability has been found in Firefox < 55.0, when the layer manager is freed too early when rendering specific SVG content, resulting in a potentially exploitable crash. - CVE-2017-7807 (content spoofing) A domain hijacking flaw has been found in Firefox < 55.0. A mechanism that uses AppCache to hijack a URL in a domain using fallback by serving the files from a sub-path on the domain. This has been addressed by requiring fallback files be inside the manifest directory. - CVE-2017-7808 (information disclosure) A CSP information leak has been found in Firefox < 55.0. A content security policy (CSP) frame-ancestors directive containing origins with paths allows for comparisons against those paths instead of the origin. This results in a cross-origin information leak of this path information. - CVE-2017-7809 (arbitrary code execution) A use-after-free issue has been found in Firefox < 55.0, when an editor DOM node is deleted prematurely during tree traversal while still bound to the document. This results in a potentially exploitable crash. Impact ====== A remote attacker can access sensitive information, bypass security restrictions, crash the browser or execute arbitrary code on the affected host.
