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 Important 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-2016-1612, CVE-2016-1613, CVE-2016-1614, CVE-2016-1615, CVE-2016-1616, CVE-2016-1617, CVE-2016-1618, CVE-2016-1619, CVE-2016-1620, CVE-2016-2051, CVE-2016-2052)

All Chromium users should upgrade to these updated packages, which contain Chromium version 48.0.2564.82, which corrects these issues.
After installing the update, Chromium must be restarted for the changes to take effect.

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 :

    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 version of Google Chrome installed on the remote Windows host is prior to 48.0.2564.82. It is, therefore, affected by multiple vulnerabilities :

  - A unspecified vulnerability exists in Google V8 when     handling compatible receiver checks hidden behind     receptors. An attacker can exploit this to have an     unspecified impact. No other details are available.
    (CVE-2016-1612)

  - A user-after-free error exists in PDFium due to improper     invalidation of IPWL_FocusHandler and IPWL_Provider upon     destruction. An attacker can exploit this to deference     already freed memory, resulting in the execution of     arbitrary code. (CVE-2016-1613)

  - An unspecified vulnerability exists in Blink that is     related to the handling of bitmaps. An attacker can     exploit this to access sensitive information. No other     details are available. (CVE-2016-1614)

  - An unspecified vulnerability exists in omnibox that is     related to origin confusion. An attacker can exploit     this to have an unspecified impact. No other details are     available. (CVE-2016-1615)

  - An unspecified vulnerability exists that allows an     attacker to spoof a displayed URL. No other details are     available. (CVE-2016-1616)

  - An unspecified vulnerability exists that is related to     history sniffing with HSTS and CSP. No other details     are available. (CVE-2016-1617)

  - A flaw exists in Blink due to the weak generation of     random numbers by the ARC4-based random number     generator. An attacker can exploit this to gain     access to sensitive information. No other details are     available. (CVE-2016-1618)

  - A out-of-bounds read error exists in PDFium in file     fx_codec_jpx_opj.cpp in the sycc4{22,44}_to_rgb()     functions. An attacker can exploit this to cause a     denial of service by crashing the application linked     using the library. (CVE-2016-1619)

  - Multiple vulnerabilities exist, the most serious of     which allow an attacker to execute arbitrary code via a     crafted web page. (CVE-2016-1620)

This update also enables SSE2 support on x86_64, VA-API hardware acceleration and fixes a crash when trying to enable the Chromecast extension.

A bad cast 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 render process.
(CVE-2016-1612)

An issue was discovered when initializing the UnacceleratedImageBufferSurface class in Blink. If a user were tricked in to opening a specially crafted website, an attacker could potentially exploit this to obtain sensitive information.
(CVE-2016-1614)

An issue was discovered with the CSP implementation in Blink. If a user were tricked in to opening a specially crafted website, an attacker could potentially exploit this to determine whether specific HSTS sites had been visited by reading a CSP report. (CVE-2016-1617)

An issue was discovered with random number generator in Blink. An attacker could potentially exploit this to defeat cryptographic protection mechanisms. (CVE-2016-1618)

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-2016-1620)

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-2016-2051)

Multiple security issues were discovered in Harfbuzz. 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 renderer crash or execute arbitrary code with the privileges of the sandboxed render process. (CVE-2016-2052).
