"The remote Alibaba Cloud Linux 3 host has packages installed that are affected by multiple vulnerabilities as referenced
in the ALINUX3-SA-2025:0067 advisory.

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

    CVE-2024-1394:
    A memory leak flaw was found in Golang in the RSA encrypting/decrypting code, which might lead to a
    resource exhaustion vulnerability using attacker-controlled inputs. The memory leak happens in
    github.com/golang-fips/openssl/openssl/rsa.go#L113. The objects leaked are pkey and ctx. That
    function uses named return parameters to free pkey and ctx if there is an error initializing the
    context or setting the different properties. All return statements related to error cases follow the
    return nil, nil, fail(...) pattern, meaning that pkey and ctx will be nil inside the deferred
    function that should free them.

    CVE-2024-34158:
    Calling Parse on a // +build build tag line with deeply nested expressions can cause a panic due to
    stack exhaustion.

    CVE-2024-9355:
    A vulnerability was found in Golang FIPS OpenSSL. This flaw allows a malicious user to randomly cause an
    uninitialized buffer length variable with a zeroed buffer to be returned in FIPS mode. It may also be
    possible to force a false positive match between non-equal hashes when comparing a trusted computed hmac
    sum to an untrusted input sum if an attacker can send a zeroed buffer in place of a pre-computed sum. It
    is also possible to force a derived key to be all zeros instead of an unpredictable value. This may have
    follow-on implications for the Go TLS stack.

    CVE-2025-30204:
    golang-jwt is a Go implementation of JSON Web Tokens. Starting in version 3.2.0 and prior to versions
    5.2.2 and 4.5.2, the function parse.ParseUnverified splits (via a call to strings.Split) its argument
    (which is untrusted data) on periods. As a result, in the face of a malicious request whose Authorization
    header consists of Bearer  followed by many period characters, a call to that function incurs allocations
    to the tune of O(n) bytes (where n stands for the length of the function's argument), with a constant
    factor of about 16. This issue is fixed in 5.2.2 and 4.5.2.
