The download implementation in Google Chrome before 50.0.2661.75 on Android allows remote attackers to bypass intended pathname restrictions via unspecified vectors.

The version of Google Chrome for Android on the remote mobile host is prior to 50.0.2661.75 and thus is unpatched for a flaw that is triggered as the names of downloaded files from the content disposition are not properly sanitized.  This may allow a context-dependent attacker to bypass file path restrictions.

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.

Chromium was updated to 50.0.2661.75 to fix the following vulnerabilities :

  - CVE-2016-1651: Out-of-bounds read in Pdfium JPEG2000     decoding

  - CVE-2016-1652: Universal XSS in extension bindings

  - CVE-2016-1653: Out-of-bounds write in V8

  - CVE-2016-1654: Uninitialized memory read in media

  - CVE-2016-1655: Use-after-free related to extensions

  - CVE-2016-1656: Android downloaded file path restriction     bypass

  - CVE-2016-1657: Address bar spoofing

  - CVE-2016-1658: Potential leak of sensitive information     to malicious extensions

  - CVE-2016-1659: Various fixes from internal audits,     fuzzing and other initiatives

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)

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)

The version of Google Chrome installed on the remote Windows 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)
