Multiple unspecified vulnerabilities in Google Chrome before 50.0.2661.75 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-201605-02 (Chromium: Multiple vulnerabilities)

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

    A remote attacker could possibly execute arbitrary code with the       privileges of the process, cause a Denial of Service condition, obtain       sensitive information, or bypass security restrictions.
  Workaround :

    There is no known workaround at this time.

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)

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 50.0.2661.75.

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. (CVE-2016-1652, CVE-2016-1653, CVE-2016-1651, CVE-2016-1654, CVE-2016-1655, CVE-2016-1656, CVE-2016-1657, CVE-2016-1658, CVE-2016-1659)

Several vulnerabilities have been discovered in the chromium web browser.

  - CVE-2016-1651     An out-of-bounds read issue was discovered in the pdfium     library.

  - CVE-2016-1652     A cross-site scripting issue was discovered in extension     bindings.

  - CVE-2016-1653     Choongwoo Han discovered an out-of-bounds write issue in     the v8 JavaScript library.

  - CVE-2016-1654     Atte Kettunen discovered an uninitialized memory read     condition.

  - CVE-2016-1655     Rob Wu discovered a use-after-free issue related to     extensions.

The version of Google Chrome installed on the remote Mac OS X host is prior to 50.0.2661.75. It is, therefore, affected by multiple vulnerabilities :

  - An out-of-bounds read error exists in PDFium in the     sycc420_to_rgb() and sycc422_to_rgb() functions within     file fxcodec/codec/fx_codec_jpx_opj.cpp that is     triggered when decoding JPEG2000 images. An     unauthenticated, remote attacker can exploit this to     cause a denial of service or disclose memory contents.
    (CVE-2016-1651)

  - A cross-site scripting vulnerability exists due to     a failure by extension bindings to validate input before     returning it to users. An unauthenticated, remote     attacker can exploit this, via a crafted request, to     execute arbitrary script code in the user's browser     session. (CVE-2016-1652)

  - An out-of-bounds write error exists in Google V8,     related to the LoadBuffer operator, that is triggered     when handling typed arrays. An unauthenticated, remote     attacker can exploit this to corrupt memory, resulting     in a denial of service or the execution of arbitrary     code. (CVE-2016-1653)

  - An uninitialized memory read error exists in media     that allows an attacker to have an unspecified impact.
    No other details are available. (CVE-2016-1654)

  - A use-after-free error exists in extensions that is     triggered when handling frame removal by content     scripts. An unauthenticated, remote attacker can exploit     this to dereference already freed memory, resulting in     arbitrary code execution. (CVE-2016-1655)

  - A flaw exists, related to content disposition, due to     the improper sanitization of the names of downloaded     files. An unauthenticated, remote attacker can exploit     this to bypass path restrictions. (CVE-2016-1656)

  - A flaw exists in the FocusLocationBarByDefault()     function of the WebContentsImpl class within the file     content/browser/web_contents/web_contents_impl.cc that     allows an authenticated, remote attacker to spoof the     address bar. (CVE-2016-1657)

  - An unspecified flaw exists that allows an     unauthenticated, remote attacker to access sensitive     information by using malicious extensions.
    (CVE-2016-1658)

  - Multiple vulnerabilities exist in Chrome, the most     serious of which allow an unauthenticated, remote     attacker to execute arbitrary code. (CVE-2016-1659)
