effects/SkDashPathEffect.cpp in Skia, as used in Google Chrome before 39.0.2171.65, computes a hash key using uninitialized integer values, which might allow remote attackers to cause a denial of service by rendering crafted data.

chromium was updated to version 39.0.2171.65 to fix 13 security issues.

These security issues were fixed :

  - Use-after-free in pepper plugins (CVE-2014-7906).

  - Buffer overflow in OpenJPEG before r2911 in PDFium, as     used in Google Chromebefore 39.0.2171.65, al...
    (CVE-2014-7903).

  - Uninitialized memory read in Skia (CVE-2014-7909).

  - Unspecified security issues (CVE-2014-7910).

  - Integer overflow in media (CVE-2014-7908).

  - Integer overflow in the opj_t2_read_packet_data function     infxcodec/fx_libopenjpeg/libopenjpeg20/t2....
    (CVE-2014-7901).

  - Use-after-free in blink (CVE-2014-7907).

  - Address bar spoofing (CVE-2014-7899).

  - Buffer overflow in Skia (CVE-2014-7904).

  - Use-after-free vulnerability in the CPDF_Parser     (CVE-2014-7900).

  - Use-after-free vulnerability in PDFium allows DoS     (CVE-2014-7902).

  - Flaw allowing navigation to intents that do not have the     BROWSABLE category (CVE-2014-7905).

  - Double-free in Flash (CVE-2014-0574).

The remote host is affected by the vulnerability described in GLSA-201412-13 (Chromium: Multiple vulnerabilities)

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

    A remote attacker may be able to execute arbitrary code with the       privileges of the process or cause a Denial of Service condition.
  Workaround :

    There is no known workaround at this time.

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 or, potentially, execute arbitrary code with the privileges of the user running Chromium. (CVE-2014-7904, CVE-2014-7906, CVE-2014-7907, CVE-2014-7910, CVE-2014-7908, CVE-2014-7909)

A flaw was found in the way Chromium parsed certain URL values. A malicious attacker could use this flaw to perform phishing attacks.
(CVE-2014-7899)

All Chromium users should upgrade to these updated packages, which contain Chromium version 39.0.2171.65, which corrects these issues.
After installing the update, Chromium must be restarted for the changes to take effect.

The remote Ubuntu 14.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-2410-1 advisory.

    A buffer overflow was discovered in Skia. If a user were tricked in to opening a specially crafted     website, an attacked 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-2014-7904)

    Multiple use-after-frees were discovered in Blink. If a user were tricked in to opening a specially     crafted website, an attacked 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-2014-7907)

    An integer overflow was discovered in media. If a user were tricked in to opening a specially crafted     website, an attacked 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-2014-7908)

    An uninitialized memory read was discovered in Skia. 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-2014-7909)

    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-2014-7910)

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.

The version of Google Chrome installed on the remote Mac OS X host is a version prior to 39.0.2171.65. It is, therefore, affected by the following vulnerabilities :

  - A double-free vulnerability exists in the version of     Adobe Flash bundled with Chrome which could result in     arbitrary code execution. (CVE-2014-0574)

  - An unspecified address bar spoofing vulnerability     exists which could be used to aid in phishing attacks.
    (CVE-2014-7899)

  - Multiple use-after-free vulnerabilities exist in pdfium     which could result in arbitrary code execution.
    (CVE-2014-7900, CVE-2014-7902)

  - Integer overflow vulnerabilities exist in pdfium and     the media component which could result in arbitrary     code execution. (CVE-2014-7901, CVE-2014-7908)
