Multiple unspecified vulnerabilities in Google Chrome before 47.0.2526.73 allow attackers to cause a denial of service or possibly have other impact via unknown vectors.

The remote host is affected by the vulnerability described in GLSA-201603-09 (Chromium: Multiple vulnerabilities)

    Multiple vulnerabilities have been discovered in the Chromium web       browser. Please review the CVE identifiers referenced below for details.
  Impact :

  - Multiple vulnerabilities in V8 fixed at the tip of the     4.7 branch (currently 4.7.80.23)

The remote Ubuntu 14.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-2825-1 advisory.

    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)

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.

The version of Google Chrome installed on the remote Mac OS X host is prior to 47.0.2526.73. It is, therefore, affected by multiple vulnerabilities :

    (CVE-2015-6776)

  - A use-after-free error exists in the     notifyNodeInsertedInternal() function. An     unauthenticated, remote attacker can exploit this to     dereference already freed memory, resulting in the     execution of arbitrary code. (CVE-2015-6777)

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 Critical 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-2015-6764, CVE-2015-6765, CVE-2015-6766, CVE-2015-6767, CVE-2015-6768, CVE-2015-6769, CVE-2015-6770, CVE-2015-6771, CVE-2015-6772, CVE-2015-6773, CVE-2015-6774, CVE-2015-6775, CVE-2015-6776, CVE-2015-6777, CVE-2015-6778, CVE-2015-6779, CVE-2015-6780, CVE-2015-6781, CVE-2015-6782, CVE-2015-6784, CVE-2015-6785, CVE-2015-6786, CVE-2015-6787)
