The SharedMemory::Create function in memory/shared_memory_posix.cc in Google Chrome before 29.0.1547.57 uses weak permissions under /dev/shm/, which allows attackers to obtain sensitive information via direct access to a POSIX shared-memory file.

The version of Google Chrome installed on the remote host is a version prior to 29.0.1547.57.  It is, therefore, affected by multiple vulnerabilities :

  - Various unspecified errors exist. No further details     have been provided. (CVE-2013-2887)

  - An input validation error exists related to incomplete     paths and file handling. (CVE-2013-2900)

  - An integer overflow error exists related to 'ANGLE'.
    (CVE-2013-2901)

  - Use-after-free errors exist related to 'XSLT', the     'media' element and document parsing. (CVE-2013-2902,     CVE-2013-2903, CVE-2013-2904)

  - An error exists related to shared memory files that     could lead to the disclosure of sensitive information.
    (CVE-2013-2905)

The remote host is affected by the vulnerability described in GLSA-201309-16 (Chromium, V8: Multiple vulnerabilities)

    Multiple vulnerabilities have been discovered in Chromium and V8. Please       review the CVE identifiers and release notes referenced below for       details.
  Impact :

    A context-dependent attacker could entice a user to open a specially       crafted website or JavaScript program using Chromium or V8, possibly       resulting in the execution of arbitrary code with the privileges of the       process or a Denial of Service condition. Furthermore, a remote attacker       may be able to bypass security restrictions or have other, unspecified,       impact.
  Workaround :

    There is no known workaround at this time.

Starting from version 15, the Opera web browser uses Google's open-source Chromium rendering engine. Versions older than Opera 16 do not contain the myriad of security fixes from the contemporary version of Chromium, which is version 29. Users are advised to upgrade to Opera 16 or the latest version of Opera for security updates.

Several vulnerabilities have been discovered in the Chromium web browser.

  - CVE-2013-2887     The chrome 29 development team found various issues from     internal fuzzing, audits, and other studies.

  - CVE-2013-2900     Krystian Bigaj discovered a file handling path     sanitization issue.

  - CVE-2013-2901     Alex Chapman discovered an integer overflow issue in     ANGLE, the Almost Native Graphics Layer.

  - CVE-2013-2902     cloudfuzzer discovered a use-after-free issue in XSLT.

  - CVE-2013-2903     cloudfuzzer discovered a use-after-free issue in     HTMLMediaElement.

  - CVE-2013-2904     cloudfuzzer discovered a use-after-free issue in XML     document parsing.

  - CVE-2013-2905     Christian Jaeger discovered an information leak due to     insufficient file permissions.
