Linux Distros Unpatched Vulnerability : CVE-2023-5088

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - A bug in QEMU could cause a guest I/O operation otherwise addressed to an arbitrary disk offset to be targeted to offset 0 instead potentially overwriting the...

Amazon Linux 2 : qemu (ALAS-2023-2336)

The version of qemu installed on the remote host is prior to 3.1.0-8. It is, therefore, affected by a vulnerability as referenced in the ALAS2-2023-2336 advisory. A bug in QEMU could cause a guest I/O operation otherwise addressed to an arbitrary disk offset to be targeted to offset 0 instead...

Buffer Overflows

qemu is vulnerable to Buffer Overflows. A guest I/O address overflow vulnerability allows an attacker to overwrite arbitrary memory on the host system by exploiting a flaw in the way that QEMU handles guest I/O operations...

CVE-2023-5088

A bug in QEMU could cause a guest I/O operation otherwise addressed to an arbitrary disk offset to be targeted to offset 0 instead potentially overwriting the VM's boot code. This could be used, for example, by L2 guests with a virtual disk vdiskL2 stored on a virtual disk of an L1 vdiskL1...

CVE-2023-5088

CVE-2023-5088 is a QEMU vulnerability where an IDE guest I/O operation addressed to an arbitrary disk offset may be mis-targeted to offset 0, potentially overwriting the VM boot code. Affected context includes scenarios with nested guests (L2 reading/writing LBA0 of vdiskL1 via vdiskL2). Public r...

CVE-2023-5088 Qemu: improper ide controller reset can lead to mbr overwrite

A bug in QEMU could cause a guest I/O operation otherwise addressed to an arbitrary disk offset to be targeted to offset 0 instead potentially overwriting the VM's boot code. This could be used, for example, by L2 guests with a virtual disk vdiskL2 stored on a virtual disk of an L1 vdiskL1...

CVE-2023-3494

The fwctl driver implements a state machine which is executed when a bhyve guest accesses certain x86 I/O ports. The interface lets the guest copy a string into a buffer resident in the bhyve process' memory. A bug in the state machine implementation can result in a buffer overflowing when copyin...
