CVE-2024-6505

A flaw was found in the virtio-net device in QEMU. When enabling the RSS feature on the virtio-net network card, the indirections_table data within RSS becomes controllable. Setting excessively large values may cause an index out-of-bounds issue, potentially resulting in heap overflow access. This flaw allows a privileged user in the guest to crash the QEMU process on the host.

It was discovered that QEMU incorrectly handled certain virtio devices. A privileged guest attacker could use this issue to cause QEMU to crash, leading to a denial of service, or possibly execute arbitrary code. This issue only affected Ubuntu 22.04 LTS and Ubuntu 24.04 LTS. (CVE-2024-3446)

It was discovered that QEMU incorrectly handled SDHCI device emulation. A guest attacker could possibly use this issue to cause QEMU to crash, leading to a denial of service. This issue only affected Ubuntu 22.04 LTS and Ubuntu 24.04 LTS. (CVE-2024-3447)

It was discovered that QEMU incorrectly handled calculating the checksum of a short-sized fragmented packet. A guest attacker could possibly use this issue to cause QEMU to crash, leading to a denial of service. This issue only affected Ubuntu 24.04 LTS. (CVE-2024-3567)

It was discovered that the QEMU qemu-img utility incorrectly handled certain crafted image files. An attacker could use this issue to cause QEMU to consume resources, leading to a denial of service, or possibly read and write to an existing external file. This issue only affected Ubuntu 22.04 LTS and Ubuntu 24.04 LTS. (CVE-2024-4467)

It was discovered that QEMU incorrectly handled the RSS feature on virtio-net devices. A privileged guest attacker could possibly use this issue to cause QEMU to crash, leading to a denial of service. This issue only affected Ubuntu 22.04 LTS and Ubuntu 24.04 LTS. (CVE-2024-6505)

It was discovered that QEMU incorrectly handled the NBD server. An attacker could use this issue to cause QEMU to consume resources, leading to a denial of service. This issue only affected Ubuntu 22.04 LTS and Ubuntu 24.04 LTS. (CVE-2024-7409)

It was discovered that QEMU incorrectly handled certain USB devices. A guest attacker could possibly use this issue to cause QEMU to crash, leading to a denial of service. This issue only affected Ubuntu 22.04 LTS and Ubuntu 24.04 LTS. (CVE-2024-8354)

It was discovered that the QEMU package incorrectly set up a binfmt_misc registration with the C (Credential) flag. A local attacker could use this with a suid/sgid binary to escalate privileges. This update will no longer run foreign-architecture binaries with suid/sgid with elevated privileges.
