\nexecute arbitrary code. This issue only affected Ubuntu 18.04 LTS, Ubuntu
\n20.04 LTS, and Ubuntu 22.04 LTS. (CVE-2022-30552, CVE-2022-30790)<\/p>\n
It was discovered that U-Boot incorrectly handled certain NFS lookup
\nreplies. A remote attacker could use this issue to cause U-Boot to crash,
\nresulting in a denial of service, or possibly execute arbitrary code. This
\nissue only affected Ubuntu 18.04 LTS, Ubuntu 20.04 LTS, and Ubuntu 22.04
\nLTS. (CVE-2022-30767)<\/p>\n
Jincheng Wang discovered that U-Boot incorrectly handled certain SquashFS
\nstructures. A local attacker could use this issue to cause U-Boot to
