Description

According to the versions of the python3 packages installed, the EulerOS Virtualization for ARM 64 installation on the remote host is affected by the following vulnerabilities :

  • In Python (CPython) 3.6 through 3.6.10, 3.7 through 3.7.6, and 3.8 through 3.8.1, an insecure dependency load upon launch on Windows 7 may result in an attacker

"According to the versions of the python3 packages installed, the
EulerOS Virtualization for ARM 64 installation on the remote host is
affected by the following vulnerabilities :

  - In Python (CPython) 3.6 through 3.6.10, 3.7 through
    3.7.6, and 3.8 through 3.8.1, an insecure dependency
    load upon launch on Windows 7 may result in an
    attacker's copy of api-ms-win-core-path-l1-1-0.dll
    being loaded and used instead of the system's copy.
    Windows 8 and later are unaffected.(CVE-2020-8315)

  - do_ed_script in pch.c in GNU patch through 2.7.6 does
    not block strings beginning with a ! character. NOTE:
    this is the same commit as for CVE-2019-13638, but the
    ! syntax is specific to ed, and is unrelated to a shell
    metacharacter.(CVE-2019-9674)

  - Python 2.7 through 2.7.17, 3.5 through 3.5.9, 3.6
    through 3.6.10, 3.7 through 3.7.6, and 3.8 through
    3.8.1 allows an HTTP server to conduct Regular
    Expression Denial of Service (ReDoS) attacks against a
    client because of
    urllib.request.AbstractBasicAuthHandler catastrophic
    backtracking.(CVE-2020-8492)

has attempted to automatically clean and format it as much as possible
without introducing additional issues.");
