hb-ot-layout-gpos-table.hh in HarfBuzz before 1.0.5 allows remote attackers to cause a denial of service (buffer over-read) or possibly have unspecified other impact via crafted data, a different vulnerability than CVE-2016-2052.

The remote Redhat Enterprise Linux 7 host has one or more packages installed that are affected by multiple vulnerabilities that have been acknowledged by the vendor but will not be patched.

  - chromium-browser: Multiple unspecified vulnerabilities in HarfBuzz before 1.0.6 (CVE-2015-8947,     CVE-2016-2052)

Note that Nessus has not tested for these issues but has instead relied on the package manager's report that the package is installed.

An issue has been found in harfbuzz, an OpenType text shaping engine.

Due to a buffer over-read, remote attackers are able to cause a denial of service or possibly have other impact via crafted data.

For Debian 8 'Jessie', this problem has been fixed in version 0.9.35-2+deb8u1.

We recommend that you upgrade your harfbuzz packages.

The remote host is affected by the vulnerability described in GLSA-201701-76 (HarfBuzz: Multiple vulnerabilities)

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

    Remote attackers, through the use of crafted data, could cause a Denial       of Service condition or have other unspecified impacts.
  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-3067-1 advisory.

    Kostya Serebryany discovered that HarfBuzz incorrectly handled memory. A remote attacker could use this     issue to cause HarfBuzz to crash, resulting in a denial of service, or possibly execute arbitrary code.
    (CVE-2015-8947)

    It was discovered that HarfBuzz incorrectly handled certain length checks. A remote attacker could use     this issue to cause HarfBuzz to crash, resulting in a denial of service, or possibly execute arbitrary     code. This issue only applied to Ubuntu 16.04 LTS. (CVE-2016-2052)

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.

This update for harfbuzz fixes the following security issues :

  - CVE-2016-2052: harfbuzz: Multiple unspecified     vulnerabilities in HarfBuzz before 1.0.6 (boo#963436)

  - CVE-2015-8947: harfbuzz: hb-ot-layout-gpos-table.hh     buffer over-read (boo#989564)

The version of Google Chrome installed on the remote host is prior to 52.0.2743.82, and is affected by multiple vulnerabilities :

 - An out-of-bounds read flaw in the 'xmlParseEndTag2()' function in 'parser.c' is triggered when parsing an end tag. This may allow a context-dependent attacker to crash a process linked against the library or potentially disclose memory contents.
 - An out-of-bounds read flaw in the 'xmlNextChar()' function in 'parserInternals.c' is triggered when parsing characters in an XML file. This may allow a context-dependent attacker to crash a process linked against the library or potentially disclose memory contents.
 - An overflow condition in the 'htmlParseName()' and 'htmlParseNameComplex()' functions of 'HTMLparser.c' is triggered as user-supplied input is not properly validated when parsing characters in a range. With a specially crafted file, a context-dependent attacker can cause a heap-based buffer overflow, resulting in a denial of service or potentially allowing the execution of arbitrary code.
 - An integer overflow condition in the 'xmlParse3986Port()' function in 'uri.c' is triggered as user-supplied input is not properly validated when handling port numbers in the URL. This may allow a context-dependent attacker to have an unspecified impact.
 - An out-of-bounds under-read flaw in the 'xmlParseConditionalSections()' and 'xmlParseElementDecl()' functions in 'parser.c' may allow a context-dependent attacker to crash a process linked against the library or potentially disclose memory contents.
 - A format string flaw in multiple functionalities is triggered as string format specifiers (e.g. %s and %x) are not properly used. This may allow a context-dependent attacker to potentially execute arbitrary code or cause a denial of service in a process linked against the library.
 - An out-of-bounds read flaw in the 'PairPosFormat1::sanitize()' function 'in hb-ot-layout-gpos-table.hh' may allow a context-dependent attacker to crash a process linked against the library or potentially disclose memory contents.
 - A flaw in 'PPAPI' is triggered when handling certain messages not sent by the browser in the plugin broker process. This may allow a context-dependent attacker to bypass the sandbox.
 - A flaw in 'web/web_state/ui/crw_web_controller.mm' is triggered when handling invalid URLs. This may allow a context-dependent attacker to conduct URL spoofing attacks.
 - A use-after-free error related to extensions may allow a context-dependent attacker to dereference already freed memory and potentially execute arbitrary code.
 - An array indexing error in the 'ByteArray::Get()' function in 'data/byte_array.cc' is triggered as user-supplied input is not properly validated. This may allow a context-dependent attacker to cause a heap-based buffer overflow, crashing a process linked against the library or potentially allowing the execution of arbitrary code.
 - A flaw in 'web/ChromeClientImpl.cpp' is triggered when handling creation of new windows by deferred frames. This may allow a context-dependent attacker to bypass the same-origin policy.
 - A flaw in 'core/loader/FrameLoader.

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.
