Multiple unspecified vulnerabilities in Google V8 before 4.7.80.23, as used in Google Chrome before 47.0.2526.80, allow attackers to cause a denial of service or possibly have other impact via unknown vectors, a different issue than CVE-2015-8478.

vendor_unpatched cve-2015-8548: Unpatched CVEs for Ubuntu Linux (cve-2015-8548)

The remote Ubuntu 14.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-2860-1 advisory.

    A race condition was discovered in the MutationObserver implementation in Blink. 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-2015-6789)

    An issue was discovered with the page serializer in Blink. If a user were tricked in to opening a     specially crafted website, an attacker could potentially exploit this to inject arbitrary script or HTML.
    (CVE-2015-6790)

    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-2015-6791)

    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-2015-8548)

    An integer overflow was discovered in the WebCursor::Deserialize function 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 application crash, or execute arbitrary code with the privileges of the user     invoking the program. (CVE-2015-8664)

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 remote Redhat Enterprise Linux 6 host has a package installed that is affected by multiple vulnerabilities as referenced in the RHSA-2015:2618 advisory.

    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-2015-6788, CVE-2015-6789, CVE-2015-6790, CVE-2015-6791)

    All Chromium users should upgrade to these updated packages, which contain     Chromium version 47.0.2526.80, which corrects these issues. After     installing the update, Chromium must be restarted for the changes to take     effect.

The version of Google Chrome installed on the remote Mac OS X host is prior to 47.0.2526.80. It is, therefore, affected by multiple vulnerabilities :

  - A type confusion error exists related to extensions that     allows an attacker to have an unspecified impact.
    (CVE-2015-6788)

  - A use-after-free error exists in Blink that is triggered     when handling updates. An unauthenticated, remote     attacker can exploit this to dereference already freed     memory, resulting in the execution of arbitrary code.
    (CVE-2015-6789)

  - An unspecified escaping issue exists in saved pages.
    (CVE-2015-6790)

  - Multiple unspecified vulnerabilities exist that an     attacker can exploit to have an unspecified impact.
    (CVE-2015-6791)

  - Multiple heap buffer overflow conditions exist that     allow an attacker to execute arbitrary code.
    (CVE-2015-8438, CVE-2015-8446)

  - Multiple memory corruption issues exist that allow an     attacker to execute arbitrary code. (CVE-2015-8045,     CVE-2015-8047, CVE-2015-8060, CVE-2015-8408,     CVE-2015-8416, CVE-2015-8417, CVE-2015-8418,     CVE-2015-8419, CVE-2015-8443, CVE-2015-8444,     CVE-2015-8451, CVE-2015-8455)

  - Multiple security bypass vulnerabilities exist that     allow an attacker to write arbitrary data to the file     system under user permissions. (CVE-2015-8453,     CVE-2015-8440,  CVE-2015-8409)

  - A stack buffer overflow condition exists that allows an     attacker to execute arbitrary code. (CVE-2015-8407,     CVE-2015-8457)

  - A type confusion error exists that allows an attacker to     execute arbitrary code. (CVE-2015-8439, CVE-2015-8456)

  - An integer overflow condition exists that allows an     attacker to execute arbitrary code. (CVE-2015-8445)
