QEMU CVE-2017-15124 Denial of Service Vulnerability
Description: VNC server implementation in Quick Emulator (QEMU) 2.11.0 and older was found to be vulnerable to an unbounded memory allocation issue, as it did not throttle the framebuffer updates sent to its client. If the client did not consume these updates, VNC server allocates growing memory to hold onto this data. A malicious remote VNC client could use this flaw to cause DoS to...

OpenStack Nova CVE-2017-18191 Local Denial of Service Vulnerability
Description: An issue was discovered in OpenStack Nova 15.x through 15.1.0 and 16.x through 16.1.1. By detaching and reattaching an encrypted volume, an attacker may access the underlying raw volume and corrupt the LUKS header, resulting in a denial of service attack on the compute host. (The same code error also results in data loss, but that is not a vulnerability because the user loses...

OpenSSL CVE-2018-0739 Denial of Service Vulnerability
Description: Constructed ASN.1 types with a recursive definition (such as can be found in PKCS7) could eventually exceed the stack given malicious input with excessive recursion. This could result in a Denial of Service attack. There are no such structures used within SSL/TLS that come from untrusted sources so this is considered safe Impact: An attacker can exploit this issue to cause denial-of-service conditions. OpenSSL...

Linux Kernel CVE-2017-7518 Privilege Escalation Vulnerability
Description: A flaw was found in the way the Linux KVM module processed the trap flag(TF) bit in EFLAGS during emulation of the syscall instruction, which leads to a debug exception(DB) being raised in the guest stack. A user/process inside a guest could use this flaw to potentially escalate their privileges inside the guest. Impact: An attacker can leverage this issue to gain elevated privileges...
