"The version of runc installed on the remote host is prior to 1.1.3-1. It is, therefore, affected by multiple
vulnerabilities as referenced in the ALAS2ECS-2025-057 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)

    A buffer overflow flaw was found in Golang's library encoding/pem. This flaw allows an attacker to use a
    large PEM input (more than 5 MB) ), causing a stack overflow in Decode, which leads to a loss of
    availability. (CVE-2022-24675)

    A broken cryptographic algorithm flaw was found in golang.org/x/crypto/ssh. This issue causes a client to
    fail authentification with RSA keys to servers that reject signature algorithms based on SHA-2, enabling
    an attacker to crash the server, resulting in a loss of availability. (CVE-2022-27191)

    A flaw was found in golang encoding/xml. When calling Decoder.Skip while parsing a deeply nested XML
    document, a panic can occur due to stack exhaustion and allows an attacker to impact system availability.
    (CVE-2022-28131)

    An integer overflow flaw was found in Golang's crypto/elliptic library. This flaw allows an attacker to
    use a crafted scaler input longer than 32 bytes, causing P256().ScalarMult or P256().ScalarBaseMult to
    panic, leading to a loss of availability. (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)

    A flaw was found in the golang standard library, io/fs. Calling Glob on a path that contains a large
    number of path separators can cause a panic issue due to stack exhaustion. This could allow an attacker to
    impact availability. (CVE-2022-30630)

    A flaw was found in golang. Calling the Reader.Read method on an archive that contains a large number of
    concatenated 0-length compressed files can cause a panic issue due to stack exhaustion. (CVE-2022-30631)

    A flaw was found in golang. Calling Glob on a path that contains a large number of path separators can
    cause a panic issue due to stack exhaustion. This can cause an attacker to impact availability.
    (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)

    A flaw was found in golang. When calling Decoder.Decode on a message that contains deeply nested
    structures, a panic can occur due to stack exhaustion and allows an attacker to impact system
    availability. (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)
