概要

リモートのWindowsホストに含まれるWebブラウザは複数の脆弱性の影響を受けます。

説明

リモートのWindowsホストにインストールされているMozilla Firefoxのバージョンが、51.0より前です。したがって、以下の複数の脆弱性による影響を受けます。

- Mozilla developers and community members Christian Holler, Gary Kwong, Andre Bargull, Jan de Mooij, Tom Schuster, and Oriol reported memory safety bugs present in Firefox 50.1 and Firefox ESR 45.6. これらのバグの一部にはメモリ破損の証拠が示されており、当社では、手間をかけることにより、これらの一部が悪用され、任意のコードが実行される可能性があると推測しています。
(CVE-2017-5373)

- Mozilla developers and community members Gary Kwong, Olli Pettay, Tooru Fujisawa, Carsten Book, Andrew McCreight, Chris Pearce, Ronald Crane, Jan de Mooij, Julian Seward, Nicolas Pierron, Randell Jesup, Esther Monchari, Honza Bambas, and Philipp reported memory safety bugs present in Firefox 50.1. 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-2017-5374)

- JIT code allocation can allow for a bypass of ASLR and DEP protections leading to potential memory corruption attacks. (CVE-2017-5375)

- Use-after-free while manipulating XSL in XSLT documents (CVE-2017-5376)

- A memory corruption vulnerability in Skia that can occur when using transforms to make gradients, resulting in a potentially exploitable crash.
(CVE-2017-5377)

- Hashed codes of JavaScript objects are shared between pages. This allows for pointer leaks because an object's address can be discovered through hash codes, and also allows for data leakage of an object's content using these hash codes. (CVE-2017-5378)

- Use-after-free vulnerability in Web Animations when interacting with cycle collection found through fuzzing. (CVE-2017-5379)

- A potential use-after-free found through fuzzing during DOM manipulation of SVG content. (CVE-2017-5380)

- The 'export' function in the Certificate Viewer can force local filesystem navigation when the 'common name' in a certificate contains slashes, allowing certificate content to be saved in unsafe locations with an arbitrary filename. (CVE-2017-5381)

- Feed preview for RSS feeds can be used to capture errors and exceptions generated by privileged content, allowing for the exposure of internal information not meant to be seen by web content. (CVE-2017-5382)

- URLs containing certain unicode glyphs for alternative hyphens and quotes do not properly trigger punycode display, allowing for domain name spoofing attacks in the location bar. (CVE-2017-5383)

- Proxy Auto-Config (PAC) files can specify a JavaScript function called for all URL requests with the full URL path which exposes more information than would be sent to the proxy itself in the case of HTTPS. Normally the Proxy Auto-Config file is specified by the user or machine owner and presumed to be non-malicious, but if a user has enabled Web Proxy Auto Detect (WPAD) this file can be served remotely. (CVE-2017-5384)

- Data sent with in multipart channels, such as the multipart/x-mixed-replace MIME type, will ignore the referrer-policy response header, leading to potential information disclosure for sites using this header.
(CVE-2017-5385)

- WebExtension scripts can use the 'data: ' protocol to affect pages loaded by other web extensions using this protocol, leading to potential data disclosure or privilege escalation in affected extensions.
(CVE-2017-5386)

- The existence of a specifically requested local file can be found due to the double firing of the 'onerror' when the 'source' attribute on a <track> tag refers to a file that does not exist if the source page is loaded locally. (CVE-2017-5387)

- A STUN server in conjunction with a large number of 'webkitRTCPeerConnection' objects can be used to send large STUN packets in a short period of time due to a lack of rate limiting being applied on e10s systems, allowing for a denial of service attack. (CVE-2017-5388)

- WebExtensions could use the 'mozAddonManager' API by modifying the CSP headers on sites with the appropriate permissions and then using host requests to redirect script loads to a malicious site. したがって、悪意のある拡張機能を使用して、明示的なユーザー許可なしに追加の拡張機能をインストールする可能性があります。
(CVE-2017-5389)

- The JSON viewer in the Developer Tools uses insecure methods to create a communication channel for copying and viewing JSON or HTTP headers data, allowing for potential privilege escalation. (CVE-2017-5390)

- Special 'about: ' pages used by web content, such as RSS feeds, can load privileged 'about: ' pages in an iframe.
If a content-injection bug were found in one of those pages this could allow for potential privilege escalation. (CVE-2017-5391)

- The 'mozAddonManager' allows for the installation of extensions from the CDN for addons.mozilla.org, a publicly accessible site. したがって、悪意のある拡張機能により、Mozilla AMOサイトに対するXSS攻撃と組み合わせて、CDNから追加の拡張機能をインストールされる可能性があります。
(CVE-2017-5393)

- A use-after-free vulnerability in the Media Decoder when working with media files when some events are fired after the media elements are freed from memory.
(CVE-2017-5396)
