Multiple unspecified vulnerabilities in Google V8 before 4.8.271.17, as used in Google Chrome before 48.0.2564.82, allow attackers to cause a denial of service or possibly have other impact via unknown vectors.

vendor_unpatched cve-2016-2051: Unpatched CVEs for Ubuntu Linux (cve-2016-2051)

The remote Ubuntu 14.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-2877-1 advisory.

    A bad cast was discovered in V8. 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-2016-1612)

    An issue was discovered when initializing the UnacceleratedImageBufferSurface class in Blink. If a user     were tricked in to opening a specially crafted website, an attacker could potentially exploit this to     obtain sensitive information. (CVE-2016-1614)

    An issue was discovered with the CSP implementation in Blink. If a user were tricked in to opening a     specially crafted website, an attacker could potentially exploit this to determine whether specific HSTS     sites had been visited by reading a CSP report. (CVE-2016-1617)

    An issue was discovered with random number generator in Blink. An attacker could potentially exploit this     to defeat cryptographic protection mechanisms. (CVE-2016-1618)

    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-2016-1620)

    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-2016-2051)

    Multiple security issues were discovered in Harfbuzz. 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 renderer     crash or execute arbitrary code with the privileges of the sandboxed render process. (CVE-2016-2052)

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Updated chromium-browser packages that fix multiple security issues are now available for Red Hat Enterprise Linux 6 Supplementary.

Red Hat Product Security has rated this update as having Important security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section.

Chromium is an open source web browser, powered by WebKit (Blink).

Several flaws were found in the processing of malformed web content. A web page containing malicious content could cause Chromium to crash, execute arbitrary code, or disclose sensitive information when visited by the victim. (CVE-2016-1612, CVE-2016-1613, CVE-2016-1614, CVE-2016-1615, CVE-2016-1616, CVE-2016-1617, CVE-2016-1618, CVE-2016-1619, CVE-2016-1620, CVE-2016-2051, CVE-2016-2052)

All Chromium users should upgrade to these updated packages, which contain Chromium version 48.0.2564.82, which corrects these issues.
After installing the update, Chromium must be restarted for the changes to take effect.
