Multiple unspecified vulnerabilities in Google V8 before 4.9.385.33, as used in Google Chrome before 49.0.2623.108, allow attackers to cause a denial of service or possibly have other impact via unknown vectors.

The remote Ubuntu 14.04 LTS / 16.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-2955-1 advisory.

    A use-after-free was discovered when responding synchronously to permission requests. 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-2016-1578)

    An out-of-bounds read 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.
    (CVE-2016-1646)

    A use-after-free was discovered in the navigation implementation in Chromium 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 application crash, or execute arbitrary code with the privileges of the user     invoking the program. (CVE-2016-1647)

    A buffer overflow was discovered in ANGLE. 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-2016-1649)

    An out-of-bounds write 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 renderer process. (CVE-2016-1653)

    An invalid read was discovered in the media subsystem 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. (CVE-2016-1654)

    It was discovered that frame removal during callback execution could trigger a use-after-free 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 renderer process. (CVE-2016-1655)

    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-2016-1659)

    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-2016-3679)

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.

Chromium was updated to 49.0.2623.110 to fix the following security issues :

  - CVE-2016-1646: Out-of-bounds read in V8

  - CVE-2016-1647: Use-after-free in Navigation

  - CVE-2016-1648: Use-after-free in Extensions

  - CVE-2016-1649: Buffer overflow in libANGLE

  - CVE-2016-1650: Various fixes from internal audits,     fuzzing and other initiatives

  - CVE-2016-3679: Multiple vulnerabilities in V8 fixed at     the tip of the 4.9 branch (currently 4.9.385.33)

An update for chromium-browser is now available for Red Hat Enterprise Linux 6 Supplementary.

Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.

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

This update upgrades Chromium to version 49.0.2623.108.

Security Fix(es) :

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.
