CVE-2019-0067 Junos OS: Kernel crash (vmcore) upon receipt of a specific link-local IPv6 packet on devices configured with Multi-Chassis Link Aggregation Group (MC-LAG)

Receipt of a specific link-local IPv6 packet destined to the RE may cause the system to crash and restart vmcore. By continuously sending a specially crafted IPv6 packet, an attacker can repeatedly crash the system causing a prolonged Denial of Service DoS. This issue affects Juniper Networks Jun...

Updated kernel packages fix security vulnerabilities

This kernel update is based on the upstream 4.14.145 and fixes at least the following security issues: There is heap-based buffer overflow in the marvell wifi chip driver that allows local users to cause a denial of servicesystem crash or possibly execute arbitrary code CVE-2019-14814,...

Kernel: KVM: nVMX: guest accesses L0 MSR causes potential DoS

A flaw was found in the way KVM hypervisor handled x2APIC Machine Specific Register MSR access with nested=1 virtualization enabled. In that, L1 guest could access L0's APIC register values via L2 guest, when 'virtualize x2APIC mode' is enabled. A guest could use this flaw to potentially crash th...

CVE-2019-15239

The CVE-2019-15239 issue arises from a backported net/ipv4/tcp_output.c change in some 4.9.x and 4.14.x long-term Linux kernels that was correctly fixed in 4.16.12 but incorrectly backported to older LT kernels. This regression enables a local attacker to add to a write queue between disconnectio...

Unspecified vulnerability in Linux kernel (CNVD-2019-38269)

Linux kernel is the kernel used by Linux, the open source operating system released by the Linux Foundation in the United States. A security vulnerability exists in the implementation of overlayfs in Linux kernel 3.10 and earlier versions. An attacker could exploit this vulnerability to cause a...

kernel: NULL pointer dereference in xfs_da_shrink_inode function

An issue was discovered in the XFS filesystem in fs/xfs/libxfs/xfsattrleaf.c in the Linux kernel. A NULL pointer dereference may occur for a corrupted xfs image after xfsdashrinkinode is called with a NULL bp. This can lead to a system crash and a denial of service...

kernel: overlayfs: NULL pointer dereference in ovl_posix_acl_create function in fs/overlayfs/dir.c

A vulnerability was found in Linux kernel's implementation of overlayfs. An attacker with local access can create a denial of service situation via NULL pointer dereference in ovlposixaclcreate function in fs/overlayfs/dir.c. This can allow attackers with ability to create directories on overlayf...
