    Package        : edk2     CVE ID         : CVE-2023-48733

    Mate Kukri discovered the Debian build of EDK2, a UEFI firmware     implementation, used an insecure default configuration which could result     in Secure Boot bypass via the UEFI shell.

    This updates disables the UEFI shell if Secure Boot is used.

    For the oldstable distribution (bullseye), this problem has been fixed     in version 2020.11-2+deb11u2.

    For the stable distribution (bookworm), this problem has been fixed in     version 2022.11-6+deb12u1. This update also addresses several security     issues in the ipv6 network stack (CVE-2022-36763, CVE-2022-36764,     CVE-2022-36765, CVE-2023-45230, CVE-2023-45229, CVE-2023-45231,     CVE-2023-45232, CVE-2023-45233, CVE-2023-45234, CVE-2023-45235)

    We recommend that you upgrade your edk2 packages.

    For the detailed security status of edk2 please refer to     its security tracker page at:

Tenable has extracted the preceding description block directly from the Debian security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The version of AHV installed on the remote host is prior to 20230302.102005. It is, therefore, affected by multiple vulnerabilities as referenced in the NXSA-AHV-20230302.101026 advisory.

  - A crafted NTFS image can trigger a heap-based buffer overflow, caused by an unsanitized attribute in     ntfs_get_attribute_value, in NTFS-3G < 2021.8.22. (CVE-2021-39263)

  - EDK2's Network Package is susceptible to a buffer overflow vulnerability when processing DNS Servers     option from a DHCPv6 Advertise message. This vulnerability can be exploited by an attacker to gain     unauthorized access and potentially lead to a loss of Confidentiality, Integrity and/or Availability.
    (CVE-2023-45234)

  - Certain DNSSEC aspects of the DNS protocol (in RFC 4033, 4034, 4035, 6840, and related RFCs) allow remote     attackers to cause a denial of service (CPU consumption) via one or more DNSSEC responses, aka the     KeyTrap issue. One of the concerns is that, when there is a zone with many DNSKEY and RRSIG records, the     protocol specification implies that an algorithm must evaluate all combinations of DNSKEY and RRSIG     records. (CVE-2023-50387)

  - The Closest Encloser Proof aspect of the DNS protocol (in RFC 5155 when RFC 9276 guidance is skipped)     allows remote attackers to cause a denial of service (CPU consumption for SHA-1 computations) via DNSSEC     responses in a random subdomain attack, aka the NSEC3 issue. The RFC 5155 specification implies that an     algorithm must perform thousands of iterations of a hash function in certain situations. (CVE-2023-50868)

  - close_altfile in filename.c in less before 606 omits shell_quote calls for LESSCLOSE. (CVE-2022-48624)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The version of edk2 / hvloader installed on the remote Azure Linux 3.0 host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the CVE-2023-45234 advisory.

  - EDK2's Network Package is susceptible to a buffer overflow vulnerability when processing DNS Servers     option from a DHCPv6 Advertise message. This vulnerability can be exploited by an attacker to gain     unauthorized access and potentially lead to a loss of Confidentiality, Integrity and/or Availability.

      (bsc#1218885)
    - CVE-2023-45236: predictable TCP Initial Sequence Numbers in edk2 network packages. (bsc#1218886)
    - CVE-2023-45237: use of a weak pseudorandom number generator in edk2. (bsc#1218887)
