CVE-2020-15294 (GCVE-0-2020-15294)
Vulnerability from cvelistv5 – Published: 2020-12-17 16:50 – Updated: 2024-09-16 19:40
VLAI?
Summary
Compiler Optimization Removal or Modification of Security-critical Code vulnerability in IntPeParseUnwindData() results in multiple dereferences to the same pointer. If the pointer is located in memory-mapped from the guest space, this may cause a race-condition where the generated code would dereference the same address twice, thus obtaining different values, which may lead to arbitrary code execution. This issue affects: Bitdefender Hypervisor Introspection versions prior to 1.132.2.
Severity ?
