"The remote Alibaba Cloud Linux 3 host has packages installed that are affected by multiple vulnerabilities as referenced
in the ALINUX3-SA-2021:0061 advisory.

    Package updates are available for Alibaba Cloud Linux 3 that fix the following vulnerabilities:

    CVE-2020-36317:
    In the standard library in Rust before 1.49.0, String::retain() function has a panic safety problem. It
    allows creation of a non-UTF-8 Rust string when the provided closure panics. This bug could result in a
    memory safety violation when other string APIs assume that UTF-8 encoding is used on the same string.

    CVE-2020-36323:
    In the standard library in Rust before 1.52.0, there is an optimization for joining strings that can cause
    uninitialized bytes to be exposed (or the program to crash) if the borrowed string changes after its
    length is checked.

    CVE-2021-28875:
    In the standard library in Rust before 1.50.0, read_to_end() does not validate the return value from Read
    in an unsafe context. This bug could lead to a buffer overflow.

    CVE-2021-28876:
    In the standard library in Rust before 1.52.0, the Zip implementation has a panic safety issue. It calls
    __iterator_get_unchecked() more than once for the same index when the underlying iterator panics (in
    certain conditions). This bug could lead to a memory safety violation due to an unmet safety requirement
    for the TrustedRandomAccess trait.

    CVE-2021-28877:
    In the standard library in Rust before 1.51.0, the Zip implementation calls __iterator_get_unchecked() for
    the same index more than once when nested. This bug can lead to a memory safety violation due to an unmet
    safety requirement for the TrustedRandomAccess trait.

    CVE-2021-28878:
    In the standard library in Rust before 1.52.0, the Zip implementation calls __iterator_get_unchecked()
    more than once for the same index (under certain conditions) when next_back() and next() are used
    together. This bug could lead to a memory safety violation due to an unmet safety requirement for the
    TrustedRandomAccess trait.

    CVE-2021-28879:
    In the standard library in Rust before 1.52.0, the Zip implementation can report an incorrect size due to
    an integer overflow. This bug can lead to a buffer overflow when a consumed Zip iterator is used again.

    CVE-2021-31162:
    In the standard library in Rust before 1.52.0, a double free can occur in the Vec::from_iter function if
    freeing the element panics.
