Privilege Escalation

The kernel packages contain the Linux kernel, the core of any Linux operating system. A flaw was found in the way Linux kernel's Transparent Huge Pages THP implementation handled non-huge page migration. A local, unprivileged user could use this flaw to crash the kernel by migrating transparent...

Denial Of Service (DoS)

The kernel-rt packages contain the Linux kernel, the core of any Linux operating system. It was found that the Linux kernel's implementation of vectored pipe read and write functionality did not take into account the I/O vectors that were already processed when retrying after a failed atomic acce...

Denial Of Service (DoS)

kernel is vulnerable to denial of service. It was found that reporting emulation failures to user space could lead to either a local CVE-2014-7842 or a L2-L1 CVE-2010-5313 denial of service. In the case of a local denial of service, an attacker must have access to the MMIO area or be able to acce...

UPDATE: MITRE CALDERA 2.0

PenTestIT RSS Feed I read a tweet about two days ago and today, MITRE CALDERA 2.0 is out already! If you remember, I wrote briefly about this automated adversary emulation system in my post titled - List of Adversary Emulation Tools. This is a major update and the current version supports Windows...

[SECURITY] Fedora 29 Update: qemu-3.0.0-4.fc29

QEMU is a generic and open source processor emulator which achieves a good emulation speed by using dynamic translation. QEMU has two operating modes: Full system emulation. In this mode, QEMU emulates a full system for example a PC, including a processor and various peripherials. It can be used ...

UBUNTU-CVE-2019-9824

tcpemu in slirp/tcpsubr.c aka slirp/src/tcpsubr.c in QEMU 3.0.0 uses uninitialized data in an snprintf call, leading to Information disclosure...

The vulnerability of the vgaDrawText function in the QEMU hardware emulation software allows a hacker to trigger a service failure.

The vulnerability of the vgaDrawText function in the QEMU hardware emulation software is related to incorrect validation of input data. Exploiting this vulnerability can allow an attacker to cause a system failure...

QEMU Buffer Overflow Vulnerability (CNVD-2019-03583)

QEMU aka Quick Emulator is a set of simulation processor software developed by French programmer Fabrice Bellard. The software is fast and cross-platform. A buffer overflow vulnerability exists in the 'tcpemu' routine of slirp in QEMU. An attacker can exploit this vulnerability to cause the QEMU...

The vulnerability of the Qemu-NBD hardware emulation server allows a hacker to trigger a maintenance failure.

The vulnerability of the Qemu-NBD hardware emulation server of QEMU is related to errors during connection establishment. Exploiting this vulnerability allows a remote attacker to cause a service failure by disconnecting the server from the client upon attempting to establish a connection...

Denial Of Service (DoS)

kernel is vulnerable to denial of service DoS attacks. The vulnerability exists as a race condition in arch/x86/kvm/x86.c in the Linux kernel before 2.6.38 allows L2 guest OS users to cause a denial of service L1 guest OS crash via a crafted instruction that triggers an L2 emulation failure repor...

Arbitrary Code Execution

QEMU is vulnerable to arbitrary code execution. An out-of-bounds read/write access flaw was found in the way QEMU's VGA emulation with VESA BIOS Extensions VBE support performed read/write operations using I/O port methods. A privileged guest user could use this flaw to execute arbitrary code on...

Denial Of Service (DoS)

qemu-kvm-rhev is vulnerable to denial of service DoS attacks. The vulnerability exists as a use-after-free vulnerability in hw/ide/ahci.c in QEMU, when built with IDE AHCI Emulation support, allows guest OS users to cause a denial of service instance crash or possibly execute arbitrary code via a...

Denial Of Service (DoS)

QEMU is vulnerable to denial of service. A heap-based buffer overflow flaw was discovered in the way QEMU's AMD PC-Net II Ethernet Controller emulation received certain packets in loopback mode. A privileged user with the CAPSYSRAWIO capability inside a guest could use this flaw to crash the host...

Denial Of Service (DoS)
