"The remote Alibaba Cloud Linux 3 host has packages installed that are affected by multiple vulnerabilities as referenced
in the ALINUX3-SA-2022:0180 advisory.

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

    CVE-2020-28851:
    In x/text in Go 1.15.4, an index out of range panic occurs in language.ParseAcceptLanguage while parsing
    the -u- extension. (x/text/language is supposed to be able to parse an HTTP Accept-Language header.)

    CVE-2020-28852:
    In x/text in Go before v0.3.5, a slice bounds out of range panic occurs in language.ParseAcceptLanguage
    while processing a BCP 47 tag. (x/text/language is supposed to be able to parse an HTTP Accept-Language
    header.)

    CVE-2022-1705:
    Acceptance of some invalid Transfer-Encoding headers in the HTTP/1 client in net/http before Go 1.17.12
    and Go 1.18.4 allows HTTP request smuggling if combined with an intermediate server that also improperly
    fails to reject the header as invalid.

    CVE-2022-27664:
    In net/http in Go before 1.18.6 and 1.19.x before 1.19.1, attackers can cause a denial of service because
    an HTTP/2 connection can hang during closing if shutdown were preempted by a fatal error.

    CVE-2022-30630:
    Uncontrolled recursion in Glob in io/fs before Go 1.17.12 and Go 1.18.4 allows an attacker to cause a
    panic due to stack exhaustion via a path which contains a large number of path separators.

    CVE-2022-30632:
    Uncontrolled recursion in Glob in path/filepath before Go 1.17.12 and Go 1.18.4 allows an attacker to
    cause a panic due to stack exhaustion via a path containing a large number of path separators.

    CVE-2022-30635:
    Uncontrolled recursion in Decoder.Decode in encoding/gob before Go 1.17.12 and Go 1.18.4 allows an
    attacker to cause a panic due to stack exhaustion via a message which contains deeply nested structures.

    CVE-2022-32148:
    Improper exposure of client IP addresses in net/http before Go 1.17.12 and Go 1.18.4 can be triggered by
    calling httputil.ReverseProxy.ServeHTTP with a Request.Header map containing a nil value for the
    X-Forwarded-For header, which causes ReverseProxy to set the client IP as the value of the X-Forwarded-For
    header.

    CVE-2022-32189:
    A too-short encoded message can cause a panic in Float.GobDecode and Rat GobDecode in math/big in Go
    before 1.17.13 and 1.18.5, potentially allowing a denial of service.
