security advisorydenial of servicecriticalUbuntu 25.10 QEMU Critical Denial of Service Exec USN-8161-1
Several security issues were fixed in QEMU.. ========================================================================== Ubuntu Security Notice USN-8161-1 April 09, 2026 qemu vulnerabilities ========================================================================== A security issue affects these releases of Ubuntu and its derivatives: - Ubuntu 25.10 - Ubuntu 24.04 LTS - Ubuntu 22.04 LTS Summary: Several security issues were fixed in QEMU. Software Description: - qemu: Machine emulator and virtualizer Details: It was discovered that the LSI53C895A SCSI Host Bus Adapter implementation of QEMU incorrectly handled memory. An attacker inside the guest could possibly use this issue to cause QEMU to crash, resulting in a denial of service, or possibly execute arbitrary code. (CVE-2024-6519) It was discovered that QEMU could be made to read out of bounds when reading VMDK images. If a user or an automated system were tricked into opening a specially crafted VMDK image, an attacker could possibly use this issue to leak sensitive informaton or cause QEMU to crash, resulting in a denial of service. (CVE-2026-2243) It was discovered that the virtio-snd device implementation of QEMU could be made to write out of bounds. An attacker inside the guest could possibly use this issue to cause QEMU to crash, resulting in a denial of service, or possibly execute arbitrary code. This issue only affected Ubuntu 24.04 LTS and Ubuntu 25.10. (CVE-2026-3195) It was discovered that the virtio-snd device implementation of QEMU contained an arithmetic overflow. An attacker inside the guest could possibly use this issue to cause QEMU to crash, resulting in a denial of service, or possibly execute arbitrary code. This issue only affected Ubuntu 24.04 LTS and Ubuntu 25.10. (CVE-2026-3196) It was discovered that the Hyper-V Synthetic Debugging device implementation of QEMU could me made to write out of bounds. An attacker inside the guest could possibly use this issue to cause QEMU to crash, resulting in a denial of service, orpossibly execute arbitrary code. This issue only affected Ubuntu 24.04 LTS and Ubuntu 25.10. (CVE-2026-3842) Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 25.10 qemu-system 1:10.1.0+ds-5ubuntu2.6 qemu-system-arm 1:10.1.0+ds-5ubuntu2.6 qemu-system-common 1:10.1.0+ds-5ubuntu2.6 qemu-system-data 1:10.1.0+ds-5ubuntu2.6 qemu-system-gui 1:10.1.0+ds-5ubuntu2.6 qemu-system-mips 1:10.1.0+ds-5ubuntu2.6 qemu-system-misc 1:10.1.0+ds-5ubuntu2.6 qemu-system-modules-opengl 1:10.1.0+ds-5ubuntu2.6 qemu-system-modules-spice 1:10.1.0+ds-5ubuntu2.6 qemu-system-ppc 1:10.1.0+ds-5ubuntu2.6 qemu-system-riscv 1:10.1.0+ds-5ubuntu2.6 qemu-system-s390x 1:10.1.0+ds-5ubuntu2.6 qemu-system-sparc 1:10.1.0+ds-5ubuntu2.6 qemu-system-x86 1:10.1.0+ds-5ubuntu2.6 qemu-system-x86-xen 1:10.1.0+ds-5ubuntu2.6 qemu-system-xen 1:10.1.0+ds-5ubuntu2.6 Ubuntu 24.04 LTS qemu-system 1:8.2.2+ds-0ubuntu1.16 qemu-system-arm 1:8.2.2+ds-0ubuntu1.16 qemu-system-common 1:8.2.2+ds-0ubuntu1.16 qemu-system-data 1:8.2.2+ds-0ubuntu1.16 qemu-system-gui 1:8.2.2+ds-0ubuntu1.16 qemu-system-mips 1:8.2.2+ds-0ubuntu1.16 qemu-system-misc 1:8.2.2+ds-0ubuntu1.16 qemu-system-modules-opengl 1:8.2.2+ds-0ubuntu1.16 qemu-system-modules-spice 1:8.2.2+ds-0ubuntu1.16 qemu-system-ppc 1:8.2.2+ds-0ubuntu1.16 qemu-system-s390x 1:8.2.2+ds-0ubuntu1.16 qemu-system-sparc 1:8.2.2+ds-0ubuntu1.16 qemu-system-x86 1:8.2.2+ds-0ubuntu1.16 qemu-system-x86-xen 1:8.2.2+ds-0ubuntu1.16 qemu-system-xen 1:8.2.2+ds-0ubuntu1.16 Ubuntu 22.04 LTS qemu 1:6.2+dfsg-2ubuntu6.30 qemu-system 1:6.2+dfsg-2ubuntu6.30 qemu-system-arm 1:6.2+dfsg-2ubuntu6.30 qemu-system-common 1:6.2+dfsg-2ubuntu6.30 qemu-system-data 1:6.2+dfsg-2ubuntu6.30 qemu-system-gui 1:6.2+dfsg-2ubuntu6.30 qemu-system-mips 1:6.2+dfsg-2ubuntu6.30 qemu-system-misc 1:6.2+dfsg-2ubuntu6.30 qemu-system-ppc 1:6.2+dfsg-2ubuntu6.30 qemu-system-s390x 1:6.2+dfsg-2ubuntu6.30 qemu-system-sparc 1:6.2+dfsg-2ubuntu6.30 qemu-system-x86 1:6.2+dfsg-2ubuntu6.30 qemu-system-x86-microvm 1:6.2+dfsg-2ubuntu6.30 qemu-system-x86-xen 1:6.2+dfsg-2ubuntu6.30 After a standard system update you need to restart all QEMU virtual machines to make all the necessary changes.

security advisorydenial of serviceUbuntuUbuntu 22.04 LTS DjVuLibre Important Denial of Service USN-8054-1
Several security issues were fixed in DjVuLibre.. ========================================================================== Ubuntu Security Notice USN-8054-1 February 23, 2026 djvulibre vulnerabilities ========================================================================== A security issue affects these releases of Ubuntu and its derivatives: - Ubuntu 24.04 LTS - Ubuntu 22.04 LTS - Ubuntu 20.04 LTS - Ubuntu 18.04 LTS - Ubuntu 16.04 LTS Summary: Several security issues were fixed in DjVuLibre. Software Description: - djvulibre: DjVu image format library and tools Details: It was discovered that DjVuLibre could be forced to execute a division by zero in certain instances. A remote attacker could possibly use this issue to cause applications to stop responding or crash, resulting in a denial of service. (CVE-2021-46312) It was discovered that DjVuLibre incorrectly handled certain memory operations. If a user or automated system were tricked into processing a specially crafted DjVu file, a remote attacker could cause applications to stop responding or crash, resulting in a denial of service, or possibly execute arbitrary code. This issue only affected Ubuntu 16.04 LTS, Ubuntu 18.04 LTS, and Ubuntu 20.04 LTS. (CVE-2025-53367) Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 24.04 LTS libdjvulibre21 3.5.28-2ubuntu0.24.04.2 Ubuntu 22.04 LTS libdjvulibre21 3.5.28-2ubuntu0.22.04.2 Ubuntu 20.04 LTS libdjvulibre21 3.5.27.1-14ubuntu0.1+esm1 Available with Ubuntu Pro Ubuntu 18.04 LTS libdjvulibre21 3.5.27.1-8ubuntu0.4+esm1 Available with Ubuntu Pro Ubuntu 16.04 LTS libdjvulibre21 3.5.27.1-5ubuntu0.1+esm3 Available with Ubuntu Pro In general, a standard system update will make all the necessary changes.

ATTENTION: Due to an unavoidable ABI change the kernel updates have been given a new version number, which requires you to recompile and reinstall all third party kernel modules you might have installed. Unless you manually uninstalled the standard kernel metapackages (e.g. linux-generic, linux-generic-lts-RELEASE, linux-virtual, linux-powerpc), a standard system upgrade will automatically perform this as well.
