The remote Ubuntu 18.04 LTS / 20.04 LTS / 22.04 LTS / 22.10 host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-5764-1 advisory.

  - There exists an unchecked length field in UBoot. The U-Boot DFU implementation does not bound the length     field in USB DFU download setup packets, and it does not verify that the transfer direction corresponds to     the specified command. Consequently, if a physical attacker crafts a USB DFU download setup packet with a     `wLength` greater than 4096 bytes, they can write beyond the heap-allocated request buffer.
    (CVE-2022-2347)

  - Das U-Boot 2022.01 has a Buffer Overflow. (CVE-2022-30552)

  - nfs_lookup_reply in net/nfs.c in Das U-Boot through 2022.04 (and through 2022.07-rc2) has an unbounded     memcpy with a failed length check, leading to a buffer overflow. NOTE: this issue exists because of an     incorrect fix for CVE-2019-14196. (CVE-2022-30767)

  - Das U-Boot 2022.01 has a Buffer Overflow, a different issue than CVE-2022-30552. (CVE-2022-30790)

  - Das U-Boot from v2020.10 to v2022.07-rc3 was discovered to contain an out-of-bounds write via the function     sqfs_readdir(). (CVE-2022-33103)

  - squashfs filesystem implementation of U-Boot versions from v2020.10-rc2 to v2022.07-rc5 contains a heap-     based buffer overflow vulnerability due to a defect in the metadata reading process. Loading a specially     crafted squashfs image may lead to a denial-of-service (DoS) condition or arbitrary code execution.
    (CVE-2022-33967)

  - In Das U-Boot through 2022.07-rc5, an integer signedness error and resultant stack-based buffer overflow     in the i2c md command enables the corruption of the return address pointer of the do_i2c_md function.
    (CVE-2022-34835)

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