New! Vulnerability Priority Rating (VPR)
Tenable calculates a dynamic VPR for every vulnerability. VPR combines vulnerability information with threat intelligence and machine learning algorithms to predict which vulnerabilities are most likely to be exploited in attacks. Read more about what VPR is and how it's different from CVSS.

Synopsis
The remote Ubuntu host is missing a security-related patch.
Description
Multiple use-after-free bugs were discovered in the application cache implementation in Chromium. If a user were tricked in to opening a specially crafted website, an attacker could potentially exploit these to cause a denial of service via application crash, or execute arbitrary code with the privileges of the user invoking the program.
(CVE-2015-6765, CVE-2015-6766, CVE-2015-6767)
Several security issues were discovered in the DOM implementation in Chromium. If a user were tricked in to opening a specially crafted website, an attacker could potentially exploit these to bypass same origin restrictions. (CVE-2015-6768, CVE-2015-6770)
A security issue was discovered in the provisional-load commit implementation in Chromium. If a user were tricked in to opening a specially crafted website, an attacker could potentially exploit this to bypass same origin restrictions. (CVE-2015-6769)
An out-of-bounds read was discovered in the array map and filter operations in V8 in some circumstances. If a user were tricked in to opening a specially crafted website, an attacker could potentially exploit this to cause a denial of service via renderer crash.
(CVE-2015-6771)
It was discovered that the DOM implementation in Chromium does not prevent javascript: URL navigation while a document is being detached.
If a user were tricked in to opening a specially crafted website, an attacker could potentially exploit this to bypass same origin restrictions. (CVE-2015-6772)
An out-of bounds read was discovered in Skia in some cirumstances. If a user were tricked in to opening a specially crafted website, an attacker could potentially exploit this to cause a denial of service via renderer crash. (CVE-2015-6773)
A use-after-free was discovered in the DOM implementation in Chromium.
If a user were tricked in to opening a specially crafted website, an attacker could potentially exploit this to cause a denial of service via renderer crash or execute arbitrary code with the privileges of the sandboxed render process. (CVE-2015-6777)
It was discovered that the Document::open function in Chromium did not ensure that page-dismissal event handling is compatible with modal dialog blocking. If a user were tricked in to opening a specially crafted website, an attacker could potentially exploit this to spoof application UI content. (CVE-2015-6782)
It was discovered that the page serializer in Chromium mishandled MOTW comments for URLs in some circumstances. An attacker could potentially exploit this to inject HTML content. (CVE-2015-6784)
It was discovered that the Content Security Policy (CSP) implementation in Chromium accepted an x.y hostname as a match for a
*.x.y pattern. An attacker could potentially exploit this to bypass intended access restrictions. (CVE-2015-6785)
It was discovered that the Content Security Policy (CSP) implementation in Chromium accepted blob:, data: and filesystem: URLs as a match for a * pattern. An attacker could potentially exploit this to bypass intended access restrictions. (CVE-2015-6786)
Multiple security issues were discovered in Chromium. If a user were tricked in to opening a specially crafted website, an attacker could potentially exploit these to read uninitialized memory, cause a denial of service via application crash or execute arbitrary code with the privileges of the user invoking the program. (CVE-2015-6787)
Multiple security issues were discovered in V8. If a user were tricked in to opening a specially crafted website, an attacker could potentially exploit these to read uninitialized memory, cause a denial of service via renderer crash or execute arbitrary code with the privileges of the sandboxed render process. (CVE-2015-8478).
Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
Solution
Update the affected liboxideqtcore0 package.
