Xen vCPU context-switch implementation process security bypass vulnerability

Xen is an open source virtual machine monitor product developed at the University of Cambridge in the United Kingdom. A security vulnerability in Xen's vCPU context-switch implementation allows an attacker to exploit the vulnerability to compromise ASLR and other protection mechanisms...

Ubuntu 12.04 LTS : linux vulnerabilities (USN-2996-1)

Jann Horn discovered that eCryptfs improperly attempted to use the mmap handler of a lower filesystem that did not implement one, causing a recursive page fault to occur. A local unprivileged attacker could use to cause a denial of service system crash or possibly execute arbitrary code with...

CVE-2014-3125

Xen 4.4.x, when running on an ARM system, does not properly context switch the CNTKCTLEL1 register, which allows local guest users to modify the hardware timers and cause a denial of service crash via unspecified vectors...

CVE-2014-3125

CVE-2014-3125 concerns Xen 4.4.x on ARM where CNTKCTL_EL1 register is not properly context switched. This allows a local guest to modify hardware timers and, per the XSA-91 advisory, may enable a guest kernel to reconfigure timer interrupts for the entire system, potentially causing a denial of s...
