CVE-2024-4693

Updating...

A flaw was found in the QEMU Virtio PCI Bindings (hw/virtio/virtio-pci.c). An improper release and use of the irqfd for vector 0 during the boot process leads to a guest triggerable crash via vhost_net_stop(). This flaw allows a malicious guest to crash the QEMU process on the host.

CVE-2024-23332

Updating...

The Notary Project is a set of specifications and tools intended to provide a cross-industry standard for securing software supply chains by using authentic container images and other OCI artifacts. An external actor with control of a compromised container registry can provide outdated versions of OCI artifacts, such as Images. This could lead artifact consumers with relaxed trust policies (such as `permissive` instead of `strict`) to potentially use artifacts with signatures that are no longer valid, making them susceptible to any exploits those artifacts may contain. In Notary Project, an artifact publisher can control the validity period of artifact by specifying signature expiry during the signing process. Using shorter signature validity periods along with processes to periodically resign artifacts, allows artifact producers to ensure that their consumers will only receive up-to-date artifacts. Artifact consumers should correspondingly use a `strict` or equivalent trust policy that enforces signature expiry. Together these steps enable use of up-to-date artifacts and safeguard against rollback attack in the event of registry compromise. The Notary Project offers various signature validation options such as `permissive`, `audit` and `skip` to support various scenarios. These scenarios includes 1) situations demanding urgent workload deployment, necessitating the bypassing of expired or revoked signatures; 2) auditing of artifacts lacking signatures without interrupting workload; and 3) skipping of verification for specific images that might have undergone validation through alternative mechanisms. Additionally, the Notary Project supports revocation to ensure the signature freshness. Artifact publishers can sign with short-lived certificates and revoke older certificates when necessary. This revocation serves as a signal to inform artifact consumers that the corresponding unexpired artifact is no longer approved by the publisher. This enables the artifact publisher to control the validity of the signature independently of their ability to manage artifacts in a compromised registry.

CVE-2022-22197

Vendor: Juniper Software: Junos os evolved

An Operation on a Resource after Expiration or Release vulnerability in the Routing Protocol Daemon (RPD) of Juniper Networks Junos OS and Junos OS Evolved allows an unauthenticated network-based attacker with an established BGP session to cause a Denial of Service (DoS). This issue occurs when proxy-generate route-target filtering is enabled, and certain proxy-route add and delete events are happening. This issue affects: Juniper Networks Junos OS All versions prior to 17.3R3-S11; 17.4 versions prior to 17.4R2-S13, 17.4R3-S4; 18.3 versions prior to 18.3R3-S4; 18.4 versions prior to 18.4R1-S8, 18.4R2-S8, 18.4R3-S6; 19.1 versions prior to 19.1R3-S4; 19.2 versions prior to 19.2R1-S6, 19.2R3-S2; 19.3 versions prior to 19.3R2-S6, 19.3R3-S1; 19.4 versions prior to 19.4R1-S4, 19.4R2-S4, 19.4R3; 20.1 versions prior to 20.1R2; 20.2 versions prior to 20.2R2; 20.3 versions prior to 20.3R1-S2, 20.3R2. Juniper Networks Junos OS Evolved All versions prior to 20.1R3-EVO; 20.2 versions prior to 20.2R3-EVO; 20.3 versions prior to 20.3R2-EVO.

CVE-2021-23995

Vendor: Mozilla Software: Firefox

When Responsive Design Mode was enabled, it used references to objects that were previously freed. We presume that with enough effort this could have been exploited to run arbitrary code. This vulnerability affects Firefox ESR < 78.10, Thunderbird < 78.10, and Firefox < 88.

CVE-2020-25221

Vendor: Linux Software: Linux kernel

get_gate_page in mm/gup.c in the Linux kernel 5.7.x and 5.8.x before 5.8.7 allows privilege escalation because of incorrect reference counting (caused by gate page mishandling) of the struct page that backs the vsyscall page. The result is a refcount underflow. This can be triggered by any 64-bit process that can use ptrace() or process_vm_readv(), aka CID-9fa2dd946743.

CVE-2019-15794

Vendor: Linux Software: Linux kernel

Overlayfs in the Linux kernel and shiftfs, a non-upstream patch to the Linux kernel included in the Ubuntu 5.0 and 5.3 kernel series, both replace vma->vm_file in their mmap handlers. On error the original value is not restored, and the reference is put for the file to which vm_file points. On upstream kernels this is not an issue, as no callers dereference vm_file following after call_mmap() returns an error. However, the aufs patchs change mmap_region() to replace the fput() using a local variable with vma_fput(), which will fput() vm_file, leading to a refcount underflow.

CVE-2019-15691

Vendor: Tigervnc Software: Tigervnc

TigerVNC version prior to 1.10.1 is vulnerable to stack use-after-return, which occurs due to incorrect usage of stack memory in ZRLEDecoder. If decoding routine would throw an exception, ZRLEDecoder may try to access stack variable, which has been already freed during the process of stack unwinding. Exploitation of this vulnerability could potentially result into remote code execution. This attack appear to be exploitable via network connectivity.
