CVE-2014-3717

Xen 4.4.x does not properly validate the load address for 64-bit ARM guest kernels, which allows local users to read system memory or cause a denial of service crash via a crafted kernel, which triggers a buffer overflow...

CVE-2014-3717

Summary : The CVE affects Xen 4.4.x on 64-bit ARM, where the load address for guest kernels is not properly validated. This allows a local attacker to read system memory or cause a denial of service (crash) via a crafted kernel, due to a buffer overflow. The connected documents do not provide spe...

CVE-2014-3714

Affected software: Xen 4.4.x running on ARM images. The issue is in ARM image loading where kernel length is not properly validated, allowing a crafted 32-bit ARM guest kernel in an image to trigger a buffer overflow. Consequences described: local users can read system memory or cause a denial of...

input handling vulnerabilities loading guest kernel on ARM

ISSUE DESCRIPTION When loading a 32-bit ARM guest kernel the Xen tools did not correctly validate the length of the kernel against the actual image size. This would then lead to an overrun on the input buffer when loading the kernel into guest RAM CVE-2014-3714. Furthermore when checking a 32-bit...

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...

Hardware timer context is not properly context switched on ARM

ISSUE DESCRIPTION When running on an ARM platform Xen was not context switching the CNTKCTLEL1 register, which is used by the guest kernel to control access by userspace processes to the hardware timers. This meant that any guest can reconfigure these settings for the entire system. IMPACT A...
