The version of Google Chrome installed on the remote host is prior to 67.0.3396.62, and is affected by multiple vulnerabilities :

 - A flaw exists in the 'SRIVerifier::DidGetReadable()' function in 'fetch/FetchManager.cpp' that is triggered when handling responses that are invalid for subresource integrity (SRI) validation. This may allow a context-dependent attacker to disclose cross-origin information.
 - An out-of-bounds read flaw exists in the 'Decode()' function in 'modules/audio_coding/codecs/isac/main/source/isac.c' that is triggered when decoding iSAC encoded content. This may allow a context-dependent attacker to crash a process linked against the library or potentially disclose memory contents.
 - A flaw exists that is triggered as secure text input is not enabled for password Textfields. This may allow a physically proximate attacker to potentially view entered passwords that are not being obfuscated.
 - An out-of-bounds read flaw exists in the 'CPDF_StreamParser::ParseNextElement()' function in 'core/fpdfapi/page/cpdf_streamparser.cpp' 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 disclose sensitive memory contents.
 - An overflow condition exists that is triggered as certain input is not properly validated. This may allow a context-dependent attacker to cause a heap-based buffer overflow, resulting in a denial of service in a process linked against the library or potentially allowing the execution of arbitrary code.
 - A flaw exists in the 'CSSPaintValue::GetImage()' function in 'blink/renderer/core/css/css_paint_value.cc'. This may allow a context-dependent attacker to disclose information about the page visited status.
 - A flaw exists in the 'RenderWidgetHostImpl::WasShown()' function in 'content/browser/renderer_host/render_widget_host_impl.cc'. This may allow a context-dependent attacker to spoof the user interface.
 - A flaw exists in the 'PerformanceNavigationTiming::PerformanceNavigationTiming()' function in 'third_party/WebKit/Source/core/timing/PerformanceNavigationTiming.cpp'. This may allow a context-dependent attacker to bypass the referrer policy.
 - A flaw exists as it does not properly limit certain problematic characters 'e.g'. Cyrillic Small Letter Palochka (U+04CF) before displaying them as Unicode. With a specially crafted IDN domain, a context-dependent attacker can spoof an omnibox address.
 - An out-of-bounds read flaw exists in 'modules/video_coding/rtp_frame_reference_finder.cc' that is triggered when handling VP9 RTP frames. This may allow a context-dependent attacker to crash a process linked against the library or potentially disclose sensitive memory contents.
 - An out-of-bounds read flaw exists in the 'RtpFrameReferenceFinder::MissingRequiredFrameVp9()' function in 'modules/video_coding/rtp_frame_reference_finder.cc' that is triggered when handling VP9 temporal layers. This may allow a context-dependent attacker to crash a process linked against the library or potentially disclose sensitive memory contents.
 - A flaw exists that allows a universal cross-site scripting (UXSS) attack. This flaw exists exists because the program does not validate input before returning it to users. This may allow a context-dependent attacker to create a specially crafted request that would execute arbitrary script code in a user's browser session within the trust relationship between their browser and the server.
 - A use-after-free error exists in 'content/browser/indexed_db/indexed_db_transaction.cc' that is triggered when handling IndexedDB transactions. This may allow a context-dependent attacker to dereference already freed memory and potentially execute arbitrary code.
 - A type confusion flaw exists in the 'ReadableStreamBytesConsumer::OnFulfilled()' function in 'blink/renderer/core/fetch/readable_stream_bytes_consumer.cc'. This may allow a context-dependent attacker to potentially execute arbitrary code.
