VCID-5hjp-yuf4-dqd6
Aliases: CVE-2016-2808 |
The CESG, the Information Security Arm of GCHQ, reported that the JavaScript .watch() method could be used to overflow the 32-bit generation count of the underlying HashMap, resulting in a write to an invalid entry. Under the right conditions this write could lead to arbitrary code execution. The overflow takes considerable time and a malicious page would require a user to keep it open for the duration of the attack. | There are no reported fixed by versions. |

CVE-2016-1977
|
| VCID-24dk-u885-wuc4 | Mozilla developer Ehsan Akhgari reported two issues with Cross-origin resource sharing (CORS) "preflight" requests.The first issue is that in some circumstances the same cache key can be generated for two preflight requests on a site. As a result, if a second request is made that will match the cached key generated by an earlier request, CORS checks will be bypassed because the system will see the previously cached request as applicable.In the second issue, when some Access-Control- headers are missing from CORS responses, the values from different Access-Control- headers can be used that present in the same response. In general this flaw cannot be exploited through email in the Thunderbird product because scripting is disabled, but is potentially a risk in browser or browser-like contexts. |

CVE-2015-7197
|
| VCID-arv7-nfbr-dfc1 | Security researcher Karthikeyan Bhargavan reported an issue in Network Security Services (NSS) where the client allows for a ECDHE_ECDSA exchange where the server does not send its ServerKeyExchange message instead of aborting the handshake. Instead, the NSS client will take the EC key from the ECDSA certificate. This violates the TLS protocol and also has some security implications for forward secrecy. In this situation, the browser thinks it is engaged in an ECDHE exchange, but has been silently downgraded to a non-forward secret mixed-ECDH exchange instead. As a result, if False Start is enabled, the browser will start sending data encrypted under these non-forward-secret connection keys. This issue was fixed in NSS version 3.19.1. |
CVE-2015-2721
|
| VCID-asfc-cmcs-b7hm | Security researcher Nicolas Golubovic reported that a malicious page can overwrite files on the user's machine using Content Security Policy (CSP) violation reports. The file contents are restricted to the JSON format of the report. In many cases overwriting a local file may simply be destructive, breaking the functionality of that file. The CSP error reports can include HTML fragments which could be rendered by browsers. If a user has disabled add-on signing and has installed an "unpacked" add-on, a malicious page could overwrite one of the add-on resources. Depending on how this resource is used, this could lead to privilege escalation. In general this flaw cannot be exploited through email in the Thunderbird product because scripting is disabled, but is potentially a risk in browser or browser-like contexts. |

This issue was independently reported by security researcher laf.intel.Security researcher Massimiliano Tomassoli also discovered an integer overflow issue when parsing an invalid MPEG4 video.Mozilla security engineers Tyson Smith and Christoph Diehl used the Address Sanitizer to find a buffer overflow when parsing an MPEG4 video with an invalid size in an ESDS chunk lead to memory corruption.Each of these reported issues result in potentially exploitable crashes that could allow for remote code execution. |
CVE-2015-4493
|
| VCID-nwk4-r82n-mufd | Security researcher Ronald Crane reported three vulnerabilities affecting released code that were found through code inspection. These included one use of unowned memory, one use of a deleted object, and one memory safety bug. These do not all have clear mechanisms to be exploited through web content but are vulnerable if a mechanism can be found to trigger them. |
CVE-2015-4487
|
| VCID-pcf5-552p-27gd | Security researcher Bas Venis reported a mechanism where add-ons could be installed from a different source than user expectations. Normally, when a user enters the URL to an add-on directly in the addressbar, warning prompts are bypassed because it is the result of direct user action. He discovered that a data: URL could be manipulated on a loaded page to simulate this direct user input of the add-on's URL, which would result in a bypassing of the install permission prompt. He also reported that in the absence of the permission prompt, it is possible to cause the actual installation prompt to appear above another site's location by causing a page navigation immediately after triggering add-on installation. This could manipulate a user into falsely believing a trusted site (such as addons.mozilla.org) has initiated the installation. This could lead to users installing an add-on from a malicious source. |
CVE-2015-4498
|
| VCID-pgzb-622e-cyfw | Security researcher Mario Gomes reported that when a previously loaded image on a page is drag and dropped into content after a redirect, the redirected URL is available to scripts. This is a violation of the Fetch specification's defined behavior for "Atomic HTTP redirect handling" which states that redirected URLs are not exposed to any APIs. This can allow for information leakage. In general this flaw cannot be exploited through email in the Thunderbird product because scripting is disabled, but is potentially a risk in browser or browser-like contexts. |
CVE-2015-4519

CVE-2016-2807
|
| VCID-tekz-b2u3-8fcs | Security researcher Holger Fuhrmannek reported that a malicious Graphite "smart font" could circumvent the validation of internal instruction parameters in the Graphite 2 library using special CNTXT_ITEM instructions. This could result in arbitrary code execution. This issue affected Graphite 2 version 1.3.4, which was used in the Firefox ESR branch. To address this issue and other security vulnerabilities recently disclosed by Cisco Talos affecting this version of the library, Firefox ESR has been updated to version 1.3.5, the same one used in Firefox 44. In general this flaw cannot be exploited through email in the Thunderbird product, but is potentially a risk in browser or browser-like contexts. |
CVE-2016-1523
|
| VCID-tpju-q2sh-rbck | Security researcher Matthew Green reported a Diffie–Hellman (DHE) key processing issue in Network Security Services (NSS) where a man-in-the-middle (MITM) attacker can force a server to downgrade TLS connections to 512-bit export-grade cryptography by modifying client requests to include only export-grade cipher suites. The resulting weak key can then be leveraged to impersonate the server. This attack is detailed in the "Imperfect Forward Secrecy: How Diffie-Hellman Fails in Practice" paper and is known as the "Logjam Attack."This issue was fixed in NSS version 3.19.1 by limiting the lower strength of supported DHE keys to use 1023 bit primes. |
CVE-2015-4000
|
| VCID-tsaz-z2hg-9bcw | Security researcher Tsubasa Iinuma reported a mechanism where the displayed addressbar can be spoofed to users. This issue involves using history navigation in concert with the Location protocol property.
