"According to the versions of the icedtea-web package installed, the
EulerOS installation on the remote host is affected by the following
vulnerabilities :

  - It was found that in icedtea-web up to and including
    1.7.2 and 1.8.2 executable code could be injected in a
    JAR file without compromising the signature
    verification. An attacker could use this flaw to inject
    code in a trusted JAR. The code would be executed
    inside the sandbox.(CVE-2019-10181)

  - It was found that icedtea-web though 1.7.2 and 1.8.2
    did not properly sanitize paths from <jar/> elements in
    JNLP files. An attacker could trick a victim into
    running a specially crafted application and use this
    flaw to upload arbitrary files to arbitrary locations
    in the context of the user.(CVE-2019-10182)

  - It was found that icedtea-web up to and including 1.7.2
    and 1.8.2 was vulnerable to a zip-slip attack during
    auto-extraction of a JAR file. An attacker could use
    this flaw to write files to arbitrary locations. This
    could also be used to replace the main running
    application and, possibly, break out of the
    sandbox.(CVE-2019-10185)

Note that Tenable Network Security has extracted the preceding
description block directly from the EulerOS security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues.");
