Description

The remote Ubuntu 18.04 LTS / 20.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-5384-1 advisory.

 - A flaw null pointer dereference in the Linux kernel UDF file system functionality was found in the way user triggers udf_file_write_iter function for the malicious UDF image. A local user could use this flaw to crash the system. Actual from Linux kernel 4.2-rc1 till 5.17-rc2. (CVE-2022-0617)

 - An issue was discovered in fs/nfs/dir.c in the Linux kernel before 5.16.5. If an application sets the O_DIRECTORY flag, and tries to open a regular file, nfs_atomic_open() performs a regular lookup.
