QEMU: net: e1000e: use-after-free while sending packets

A use-after-free flaw was found in the INTEL 82574 NIC e1000e emulator of the QEMU. The issue happens while sending packets if the guest user has set the packet data address to the e1000e's MMIO address. This flaw allows a guest user or process to crash the QEMU process on the host, resulting in ...

Google TensorFlow buffer overflow vulnerability (CNVD-2021-87034)

Google TensorFlow is an end-to-end open source platform for machine learning from Google, U.S. A buffer overflow vulnerability exists in Google TensorFlow, which stems from the fact that the ImmutableConst operation can be tricked into reading arbitrary memory content. This is because the...

CVE-2021-41227

TensorFlow is an open source platform for machine learning. In affected versions the ImmutableConst operation in TensorFlow can be tricked into reading arbitrary memory contents. This is because the tstring TensorFlow string class has a special case for memory mapped strings but the operation...

CVE-2021-41227 Arbitrary memory read in `ImmutableConst`

TensorFlow is an open source platform for machine learning. In affected versions the ImmutableConst operation in TensorFlow can be tricked into reading arbitrary memory contents. This is because the tstring TensorFlow string class has a special case for memory mapped strings but the operation...

Name of the Vulnerable Software and Affected Versions: Linux kernel affected versions not specified Description: The issue is related to the clk component of the Linux kernel, where unbinding a CCU driver unmaps the device's MMIO region but leaves its clocks/resets and their providers registered...

USN-4467-2 qemu vulnerabilities

USN-4467-1 fixed several vulnerabilities in QEMU. This update provides the corresponding update for Ubuntu 14.04 ESM. Original advisory details: It was discovered that the QEMU SD memory card implementation incorrectly handled certain memory operations. An attacker inside a guest could possibly u...

QEMU 缓冲区错误漏洞

QEMU Quick Emulator is a set of simulation processor software by Fabrice Bellard, a French individual developer. The software is fast and cross-platform. QEMU 4.1.0 suffers from a security vulnerability that stems from an out-of-bounds read flaw found in the ATI VGA implementation. It occurs in t...

Race condition

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...
