"It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2023-2023-047 advisory.

  - 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-2022-1705)

  - Uncontrolled recursion in the Parse functions in go/parser before Go 1.17.12 and Go 1.18.4 allow an
    attacker to cause a panic due to stack exhaustion via deeply nested types or declarations. (CVE-2022-1962)

  - Authorization Bypass Through User-Controlled Key in GitHub repository emicklei/go-restful prior to v3.8.0.
    (CVE-2022-1996)

  - encoding/pem in Go before 1.17.9 and 1.18.x before 1.18.1 has a Decode stack overflow via a large amount
    of PEM data. (CVE-2022-24675)

  - The golang.org/x/crypto/ssh package before 0.0.0-20220314234659-1baeb1ce4c0b for Go allows an attacker to
    crash a server in certain circumstances involving AddHostKey. (CVE-2022-27191)

  - Uncontrolled recursion in Decoder.Skip in encoding/xml before Go 1.17.12 and Go 1.18.4 allows an attacker
    to cause a panic due to stack exhaustion via a deeply nested XML document. (CVE-2022-28131)

  - The generic P-256 feature in crypto/elliptic in Go before 1.17.9 and 1.18.x before 1.18.1 allows a panic
    via long scalar input. (CVE-2022-28327)

  - Go before 1.17.10 and 1.18.x before 1.18.2 has Incorrect Privilege Assignment. When called with a non-zero
    flags parameter, the Faccessat function could incorrectly report that a file is accessible.
    (CVE-2022-29526)

  - Non-random values for ticket_age_add in session tickets in crypto/tls before Go 1.17.11 and Go 1.18.3
    allow an attacker that can observe TLS handshakes to correlate successive connections by comparing ticket
    ages during session resumption. (CVE-2022-30629)

  - 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-2022-30630)

  - Uncontrolled recursion in Reader.Read in compress/gzip before Go 1.17.12 and Go 1.18.4 allows an attacker
    to cause a panic due to stack exhaustion via an archive containing a large number of concatenated 0-length
    compressed files. (CVE-2022-30631)

  - 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-2022-30632)

  - Uncontrolled recursion in Unmarshal in encoding/xml before Go 1.17.12 and Go 1.18.4 allows an attacker to
    cause a panic due to stack exhaustion via unmarshalling an XML document into a Go struct which has a
    nested field that uses the 'any' field tag. (CVE-2022-30633)

  - 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-2022-30635)

  - 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-2022-32148)
