FreeBSD : xen-kernel -- ioreq handling possibly susceptible to multiple read issue (6aa2d135-b40e-11e5-9728-002590263bf5)

The Xen Project reports : Single memory accesses in source code can be translated to multiple ones in machine code by the compiler, requiring special caution when accessing shared memory. Such precaution was missing from the hypervisor code inspecting the state of I/O requests sent to the device...

Foxit FoxitCloudUpdateService Local Elevation of Privilege Vulnerability

Foxit Reader is a small PDF document viewer and printing program. A security vulnerability exists in the FoxitCloudUpdateService of Foxit Reader. A remote attacker writing certain data in a shared memory area can trigger a memory corruption, leading to the execution of arbitrary code in the syste...

ioreq handling possibly susceptible to multiple read issue

ISSUE DESCRIPTION Single memory accesses in source code can be translated to multiple ones in machine code by the compiler, requiring special caution when accessing shared memory. Such precaution was missing from the hypervisor code inspecting the state of I/O requests sent to the device model fo...

paravirtualized drivers incautious about shared memory contents

ISSUE DESCRIPTION The compiler can emit optimizations in the PV backend drivers which can lead to double fetch vulnerabilities. Specifically the shared memory between the frontend and backend can be fetched twice during which time the frontend can alter the contents possibly leading to arbitrary...

UBUNTU-CVE-2015-8550

Xen, when used on a system providing PV backends, allows local guest OS administrators to cause a denial of service host OS crash or gain privileges by writing to memory shared between the frontend and backend, aka a double fetch vulnerability...
