"This update for nodejs14 fixes the following issues :

New upstream LTS version 14.15.4 :

  - CVE-2020-8265: use-after-free in TLSWrap (High) bug in
    TLS implementation. When writing to a TLS enabled
    socket, node::StreamBase::Write calls
    node::TLSWrap::DoWrite with a freshly allocated
    WriteWrap object as first argument. If the DoWrite
    method does not return an error, this object is passed
    back to the caller as part of a StreamWriteResult
    structure. This may be exploited to corrupt memory
    leading to a Denial of Service or potentially other
    exploits (bsc#1180553)

  - CVE-2020-8287: HTTP Request Smuggling allow two copies
    of a header field in a http request. For example, two
    Transfer-Encoding header fields. In this case Node.js
    identifies the first header field and ignores the
    second. This can lead to HTTP Request Smuggling
    (https://cwe.mitre.org/data/definitions/444.html).
    (bsc#1180554)

New upstream LTS version 14.15.3 :

  - deps :

  + upgrade npm to 6.14.9

  + update acorn to v8.0.4

  - http2: check write not scheduled in scope destructor

  - stream: fix regression on duplex end

New upstream LTS version 14.15.1 :

  - deps: Denial of Service through DNS request (High). A
    Node.js application that allows an attacker to trigger a
    DNS request for a host of their choice could trigger a
    Denial of Service by getting the application to resolve
    a DNS record with a larger number of responses
    (bsc#1178882, CVE-2020-8277)

description block directly from the SUSE security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues.");
