Authored by Ubuntu | Site security.ubuntu.com

Ubuntu Security Notice 5120-1 - It was discovered that the f2fs file system in the Linux kernel did not properly validate metadata in some situations. An attacker could use this to construct a malicious f2fs image that, when mounted and operated on, could cause a denial of service or possibly execute arbitrary code. It was discovered that the Linux kernel did not properly enforce certain types of entries in the Secure Boot Forbidden Signature Database protection mechanism. An attacker could use this to bypass UEFI Secure Boot restrictions. Various other issues were also addressed.
