The remote Ubuntu 20.04 LTS / 21.04 host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-5088-1 advisory.

  - NetworkPkg/IScsiDxe has remotely exploitable buffer overflows. (CVE-2021-38575)

    (CVE-2019-11098)

  - ASN.1 strings are represented internally within OpenSSL as an ASN1_STRING structure which contains a     buffer holding the string data and a field holding the buffer length. This contrasts with normal C strings     which are repesented as a buffer for the string data which is terminated with a NUL (0) byte. Although not     a strict requirement, ASN.1 strings that are parsed using OpenSSL's own d2i functions (and other similar     parsing functions) as well as any string whose value has been set with the ASN1_STRING_set() function will     additionally NUL terminate the byte array in the ASN1_STRING structure. However, it is possible for     applications to directly construct valid ASN1_STRING structures which do not NUL terminate the byte array     by directly setting the data and length fields in the ASN1_STRING array. This can also happen by using     the ASN1_STRING_set0() function. Numerous OpenSSL functions that print ASN.1 data have been found to     assume that the ASN1_STRING byte array will be NUL terminated, even though this is not guaranteed for     strings that have been directly constructed. Where an application requests an ASN.1 structure to be     printed, and where that ASN.1 structure contains ASN1_STRINGs that have been directly constructed by the     application without NUL terminating the data field, then a read buffer overrun can occur. The same thing     can also occur during name constraints processing of certificates (for example if a certificate has been     directly constructed by the application instead of loading it via the OpenSSL parsing functions, and the     certificate contains non NUL terminated ASN1_STRING structures). It can also occur in the     X509_get1_email(), X509_REQ_get1_email() and X509_get1_ocsp() functions. If a malicious actor can cause an     application to directly construct an ASN1_STRING and then process it through one of the affected OpenSSL     functions then this issue could be hit. This might result in a crash (causing a Denial of Service attack).
    It could also result in the disclosure of private memory contents (such as private keys, or sensitive     plaintext). Fixed in OpenSSL 1.1.1l (Affected 1.1.1-1.1.1k). Fixed in OpenSSL 1.0.2za (Affected     1.0.2-1.0.2y). (CVE-2021-3712)

  - Calls to EVP_CipherUpdate, EVP_EncryptUpdate and EVP_DecryptUpdate may overflow the output length argument     in some cases where the input length is close to the maximum permissable length for an integer on the     platform. In such cases the return value from the function call will be 1 (indicating success), but the     output length value will be negative. This could cause applications to behave incorrectly or crash.
    OpenSSL versions 1.1.1i and below are affected by this issue. Users of these versions should upgrade to     OpenSSL 1.1.1j. OpenSSL versions 1.0.2x and below are affected by this issue. However OpenSSL 1.0.2 is out     of support and no longer receiving public updates. Premium support customers of OpenSSL 1.0.2 should     upgrade to 1.0.2y. Other users should upgrade to 1.1.1j. Fixed in OpenSSL 1.1.1j (Affected 1.1.1-1.1.1i).
    Fixed in OpenSSL 1.0.2y (Affected 1.0.2-1.0.2x). (CVE-2021-23840)
