Details

Matthieu Barjole and Victor Cutillas discovered that Sudo incorrectly
handled user-specified editors when using the sudoedit command. A local
attacker that has permission to use the sudoedit command could possibly use
this issue to edit arbitrary files. (CVE-2023-22809)

It was discovered that the Protobuf-c library, used by Sudo, incorrectly
handled certain arithmetic shifts. An attacker could possibly use this
issue to cause Sudo to crash, resulting in a denial of service. This issue
only affected Ubuntu 22.04 LTS. (CVE-2022-33070)
