The remote Ubuntu 20.04 LTS / 22.04 LTS / 23.04 / 23.10 host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-6569-1 advisory.
RARLAB UnRAR before 6.12 on Linux and UNIX allows directory traversal to write to files during an extract (aka unpack) operation, as demonstrated by creating a ~/.ssh/authorized_keys file. NOTE: WinRAR and Android RAR are unaffected. (CVE-2022-30333)
Update to 0.103.10 CVE-2023-40477 (CVE-2023-40477)
Note that Nessus has not tested for these issues but has instead relied only on the applicationβs self-reported version number.
