Google Chrome before 48.0.2564.116 allows remote attackers to bypass the Blink Same Origin Policy and a sandbox protection mechanism via unspecified vectors.
Mozilla developers and community members Andreea Pavel, Christian Holler, Honza Bambas, Jason Kratzer, and Jeff Gilbert reported memory safety bugs fixed in Firefox 68, Firefox ESR 60.8, and Thunderbird 68. 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.
The parsestring function in cjson.c in the cJSON library mishandles UTF8/16 strings, which allows remote attackers to cause a denial of service (crash) or execute arbitrary code via a non-hex character in a JSON string, which triggers a heap-based buffer overflow.
Multiple unspecified vulnerabilities in the browser engine in Mozilla Firefox before 47.0 and Firefox ESR 45.x before 45.2 allow remote attackers to cause a denial of service (memory corruption and application crash) or possibly execute arbitrary code via unknown vectors.
Multiple unspecified vulnerabilities in the browser engine in Mozilla Firefox before 45.0 and Firefox ESR 38.x before 38.7 allow remote attackers to cause a denial of service (memory corruption and application crash) or possibly execute arbitrary code via unknown vectors.
The nsCSPContext::SendReports function in dom/security/nsCSPContext.cpp in Mozilla Firefox before 45.0 and Firefox ESR 38.x before 38.7 does not prevent use of a non-HTTP report-uri for a Content Security Policy (CSP) violation report, which allows remote attackers to cause a denial of service (data overwrite) or possibly gain privileges by specifying a URL of a local file.
Multiple unspecified vulnerabilities in the browser engine in Mozilla Firefox before 45.0 allow remote attackers to cause a denial of service (memory corruption and application crash) or possibly execute arbitrary code via vectors related to js/src/jit/arm/Assembler-arm.cpp, and unknown other vectors.

Multiple unspecified vulnerabilities in Google Chrome before 51.0.2704.103 allow attackers to cause a denial of service or possibly have other impact via unknown vectors.

As part of a winning Pwn2Own entry, a researcher demonstrated a sandbox escape by installing a malicious language pack and then opening a browser feature that used the compromised translation. This vulnerability affects Firefox ESR < 60.8, Firefox < 68, and Thunderbird < 60.8.
Icinga Icinga Web2 2.0.0 through 2.6.4, 2.7.4 and 2.8.2 has a Directory Traversal vulnerability which allows an attacker to access arbitrary files that are readable by the process running Icinga Web 2. This issue is fixed in Icinga Web 2 in v2.6.4, v2.7.4 and v2.8.2.
Mozilla Firefox before 45.0 on Linux, when an Intel video driver is used, allows remote attackers to cause a denial of service (memory consumption or stack memory corruption) by triggering use of a WebGL shader.
A vulnerability exists where if a user opens a locally saved HTML file, this file can use file: URIs to access other files in the same directory or sub-directories if the names are known or guessed. The Fetch API can then be used to read the contents of any files stored in these directories and they may uploaded to a server. Luigi Gubello demonstrated that in combination with a popular Android messaging app, if a malicious HTML attachment is sent to a user and they opened that attachment in Firefox, due to that app's predictable pattern for locally-saved file names, it is possible to read attachments the victim received from other correspondents.
An insufficient policy enforcement flaw was found in the audio component of the Chromium browser.

A bug in the standard library ScalarMult implementation of curve P-256 for amd64 architectures in Go before 1.7.6 and 1.8.x before 1.8.2 causes incorrect results to be generated for specific input points. An adaptive attack can be mounted to progressively extract the scalar input to ScalarMult by submitting crafted points and observing failures to the derive correct output. This leads to a full key recovery attack against static ECDH, as used in popular JWT libraries.
A vulnerability exists where the caret ("^") character is improperly escaped constructing some URIs due to it being used as a separator, allowing for possible spoofing of origin attributes.
Exposure of Private Information in Nextcloud Server 16.0.1 causes the server to send it's domain and user IDs to the Nextcloud Lookup Server without any further data when the Lookup server is disabled.
Memory leak in libstagefright in Mozilla Firefox before 45.0 and Firefox ESR 38.x before 38.7 allows remote attackers to cause a denial of service (memory consumption) via an MPEG-4 file that triggers a delete operation on an array.
Mozilla Firefox before 45.0 allows remote attackers to bypass the Same Origin Policy and obtain sensitive information by reading a Content Security Policy (CSP) violation report that contains path information associated with an IFRAME element.
The Extensions subsystem in Google Chrome before 50.0.2661.75 incorrectly relies on GetOrigin method calls for origin comparisons, which allows remote attackers to bypass the Same Origin Policy and obtain sensitive information via a crafted extension.
The WebContentsImpl::FocusLocationBarByDefault function in content/browser/webcontents/webcontentsimpl.cc in Google Chrome before 50.0.2661.75 mishandles focus for certain about:blank pages, which allows remote attackers to spoof the address bar via a crafted URL.
