A use after free in PDFium in Google Chrome prior to 61.0.3163.79 for Linux, Windows, and Mac allowed a remote attacker to potentially exploit memory corruption via a crafted PDF file.

The version of Google Chrome installed on the remote host is prior to 61.0.3163.79, and is affected by multiple vulnerabilities :

 - A use-after-free flaw exists in WebAssembly that is triggered when async compilation is enabled. This may allow a context-dependent attacker to have an unspecified impact.
 - A flaw exists that is triggered when handling the 'ExternalInterface.'addCallback'()' ActionScript method, as it works across isolated worlds. This may allow a context-dependent attacker to bypass intended security restrictions.
 - A double-free condition exists in the 'celt_header()' function in 'libavformat/oggparsecelt.c' that is triggered as certain input is not properly validated. This may allow a context-dependent attacker to crash a process linked against the library or potentially execute arbitrary code.
 - A use-after-poison flaw exists in the 'LocalFrameView::ForAllNonThrottledLocalFrameViews()' function in 'frame/LocalFrameView.cpp' that is triggered as certain input is not properly validated. This may allow a context-dependent attacker to potentially execute arbitrary code.
 - A flaw exists that is triggered when handling maximum stack space exceeded exceptions in the WritableStream and
 - An flaw exists in the SSLCommonNameMismatchHandling feature that is triggered during redirect navigation and may result in using an HTTP URL. This may allow a MitM attacker to disclose the path of the original HTTPS URL.
 - A flaw exists in the 'SkArithmeticImageFilter::Make()' function related to use of uninitialized memory. This may allow a context-dependent attacker to have an unspecified impact.
 - A flaw exists that is triggered as the Content Security Policy (CSP) is not inherited when inheriting the security origin during main window navigation. This may allow a context-dependent attacker to bypass the Content Security Policy.
 - A flaw exists in the 'SkPathMeasure::getLength()' function in 'core/SkPathMeasure.cpp' related to use of uninitialized memory. This may allow a context-dependent attacker to crash a process linked against the library or potentially execute arbitrary code.
 - An out-of-bounds write flaw exists in the 'GetFirstArgumentAsBytes()' function in '/wasm/wasm-js.cc' that is triggered when processing WebAssembly code. This may allow a context-dependent attacker to manipulate memory content and execute arbitrary code.
 - A type confusion flaw exists in the 'VirtualObject::MergeFields()' function in 'compiler/escape-analysis.cc' that is triggered as certain input is not properly validated. This may allow a context-dependent attacker to potentially execute arbitary code.
 - A flaw exists in 'core/fxcodec/codec/fx_codec_jpx_opj.cpp' that is triggered when management memory lifecycles. This may allow an context-dependent attacker to corrupt memory and potentially execute arbitrary code.
 - An integer overflow condition exists in the SkArenaAlloc class in 'core/SkArenaAlloc.cpp' that is triggered when allocating memory. This may allow a context-dependent attacker to cause a heap-based buffer overflow, potentially allowing to execute arbitrary code.
 - An overflow condition exists in the WebGL component that is triggered as certain input is not properly validated when handling ES3 pixel pack parameters. This may allow a context-dependent attacker to cause a heap-based buffer overflow and potentially execute arbitrary code.
 - A use-after-free error exists in the handling of CPWL_Wnd objects. With a specially crafted web page, a context-dependent attacker can dereference already freed memory and potentially execute arbitrary code.

The remote host is affected by the vulnerability described in GLSA-201709-15 (Chromium: Multiple vulnerabilities)

    Multiple vulnerabilities have been discovered in Chromium. Please review       the referenced CVE identifiers 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, bypass security restrictions, or spoof content.
  Workaround :

    There is no known workaround at this time.

This update for chromium to version 61.0.3163.79 fixes several issues.

The remote Redhat Enterprise Linux 6 host has a package installed that is affected by multiple vulnerabilities as referenced in the RHSA-2017:2676 advisory.

    Chromium is an open-source web browser, powered by WebKit (Blink).

    This update upgrades Chromium to version 61.0.3163.79.

    Security Fix(es):

    * Multiple 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-2017-5111, CVE-2017-5112, CVE-2017-5113, CVE-2017-5114, CVE-2017-5115,     CVE-2017-5116, CVE-2017-5117, CVE-2017-5118, CVE-2017-5119, CVE-2017-5120)
