Denial Of Service (DoS)

Linux kernel is vulnerable to denial of service DOS attacks. This is because the NFSv4 server in the Linux kernel does not properly validate layout type when processing NFSv4 pNFS LAYOUTGET and GETDEVICEINFO operands. A remote attacker could use this flaw to soft-lockup the system and thus cause ...

Denial Of Service (DoS)

The kernel packages contain the Linux kernel, the core of any Linux operating system. This update fixes the following security issues: A flaw was found in the way the Linux kernel's IPv6 implementation handled certain UDP packets when the UDP Fragmentation Offload UFO feature was enabled. A remot...

Denial Of Service (DoS)

kernel-rt is vulnerable to denial of service DoS attacks. The vulnerability exists as the nfs4getacluncached function in fs/nfs/nfs4proc.c in the NFSv4 implementation in the Linux kernel before 3.3.2 uses an incorrect length variable during a copy operation, which allows remote NFS servers to cau...

CVE-2018-17157

In FreeBSD before 11.2-STABLEr340854 and 11.2-RELEASE-p5, an integer overflow error when handling opcodes can cause memory corruption by sending a specially crafted NFSv4 request. Unprivileged remote users with access to the NFS server may be able to execute arbitrary code...
