This is a flaw in the Intel processor execution engine sharing on SMT (e.g. Hyper-Threading) architectures. It can result in leakage of secret data in applications such as OpenSSL that has secret dependent control flow at any granularity level. In order to exploit this flaw, the attacker needs to run a malicious process on the same core of the processor as the victim process.

A use-after-free flaw was found in the Linux kernel's Ext4 File System in how a user triggers several file operations simultaneously with the overlay FS usage. This flaw allows a local user to crash or potentially escalate their privileges on the system. Only if patch 9a2544037600 ("ovl: fix use after free in struct ovl_aio_req") not applied yet, the kernel could be affected.

The host is installed with kernel on RHEL 5, 6, or 7 and is prone to a buffer overflow vulnerability. A flaw is present in the application, which fails to properly handle kernel's virtio-net handled fragmented packets. Successful exploitation could allow attackers to send crafted packets to a target system.

Systems with microprocessors utilizing speculative execution and branch prediction may allow unauthorized disclosure of information to an attacker with local user access via a speculative buffer overflow and side-channel analysis.

The host is installed with ntp on Red Hat Enterprise Linux 5, 6 or 7 and is prone to a denial of service vulnerability. A flaw is present in the application, which fails to properly handle a mode 6 or mode 7 packet containing an unusually long data. Successful exploitation could allow attackers to crash ntpd.

The host is installed with ntp on Red Hat Enterprise Linux 5, 6 or 7 and is prone to a denial of service vulnerability. A flaw is present in the application, which fails to properly handle a packet with particular autokey operations. Successful exploitation could allow attackers to crash ntpd.

The host is installed with ntp on Red Hat Enterprise Linux 5, 6 or 7 and is prone to a denial of service vulnerability. A flaw is present in the application, which fails to properly handle a packet with particular autokey operations. Successful exploitation could allow attackers to crash ntpd.

The host is installed with ntp on Red Hat Enterprise Linux 5, 6 or 7 and is prone to a denial of service vulnerability. A flaw is present in the application, which fails to properly handle a packet with particular autokey operations. Successful exploitation could allow attackers to crash ntpd.

The host is installed with ntp on Red Hat Enterprise Linux 5, 6 or 7 and is prone to a memory corruption vulnerability. A flaw is present in the application, which fails to properly handle an invalid length field. Successful exploitation could could cause a buffer overflow potentially resulting in memory being modified.

The host is installed with ntp on Red Hat Enterprise Linux 5, 6 or 7 and is prone to a buffer overflow vulnerability. A flaw is present in the application, which fails to properly handle crafted data. Successful exploitation could cause a buffer overflow potentially resulting in in null byte being written out of bounds.
