### Details The external-secrets has a deployment called default-external-secrets-cert-controller, which is bound with a same-name ClusterRole. This ClusterRole has "get/list" verbs of secrets resources(https://github.com/external-secrets/external-secrets/blob/main/deploy/charts/external-secrets/templates/cert-controller-rbac.yaml#L49). It also has path/update verb of validatingwebhookconfigurations resources(https://github.com/external-secrets/external-secrets/blob/main/deploy/charts/external-secrets/templates/cert-controller-rbac.yaml#L27). As a result, if a malicious user can access the worker node which has this deployment. he/she can: 1. For the "get/list secrets" permission, he/she can abuse the SA token of this deployment to retrieve or get ALL secrets in the whole cluster, including the cluster-admin secret if created. After that, he/she can abuse the cluster-admin secret to do whatever he/she likes to the whole cluster, resulting in a cluster-level privilege escalation. 2. Fo...

Ubuntu Security Notice 6995-1 - Multiple security issues were discovered in Thunderbird. If a user were tricked into opening a specially crafted website in a browsing context, an attacker could potentially exploit these to cause a denial of service, obtain sensitive information, bypass security restrictions, cross-site tracing, or execute arbitrary code. It was discovered that Thunderbird did not properly manage certain memory operations when processing graphics shared memory. An attacker could potentially exploit this issue to escape the sandbox.

Red Hat Security Advisory 2024-6428-03 - An update is now available for Red Hat Ansible Automation Platform 2.4. Issues addressed include denial of service, memory exhaustion, remote SQL injection, and traversal vulnerabilities.

### Impact In distributed service mode, Pomerium's Authenticate service exposes pprof debug and prometheus metrics handlers to untrusted traffic. This can leak potentially sensitive environmental information or lead to limited denial of service conditions. ### Patches v0.17.1 ### Workarounds Block access to `/debug` and `/metrics` paths on the authenticate service. This can be done with any L7 proxy, including Pomerium's own proxy service. ### References https://github.com/pomerium/pomerium/pull/3212 ### For more information If you have any questions or comments about this advisory: * Open an issue in [Pomerium](https://github.com/pomerium/pomerium) * Email us at [security@pomerium.com](mailto:security@pomerium.com)

The vulnerabilities affect industrial control tech used across the healthcare and critical manufacturing sectors.

Debian Linux Security Advisory 5766-1 - Security issues were discovered in Chromium which could result in the execution of arbitrary code, denial of service, or information disclosure.

Ubuntu Security Notice 6993-1 - It was discovered that Vim incorrectly handled memory when closing a window, leading to a double-free vulnerability. If a user was tricked into opening a specially crafted file, an attacker could crash the application, leading to a denial of service, or possibly achieve code execution with user privileges. It was discovered that Vim incorrectly handled memory when adding a new file to an argument list, leading to a use-after-free. If a user was tricked into opening a specially crafted file, an attacker could crash the application, leading to a denial of service.

Ubuntu Security Notice 6992-1 - Multiple security issues were discovered in Firefox. If a user were tricked into opening a specially crafted website, an attacker could potentially exploit these to cause a denial of service, obtain sensitive information across domains, or execute arbitrary code. Nils Bars discovered that Firefox contained a type confusion vulnerability when performing certain property name lookups. An attacker could potentially exploit this issue to cause a denial of service, or execute arbitrary code.

Red Hat Security Advisory 2024-6313-03 - An update for kpatch-patch-5_14_0-284_52_1 and kpatch-patch-5_14_0-284_79_1 is now available for Red Hat Enterprise Linux 9.2 Extended Update Support. Issues addressed include a denial of service vulnerability.

### Impact sigstore-go is susceptible to a denial of service attack when a verifier is provided a maliciously crafted Sigstore Bundle containing large amounts of verifiable data, in the form of signed transparency log entries, RFC 3161 timestamps, and attestation subjects. The verification of these data structures is computationally expensive. This can be used to consume excessive CPU resources, leading to a denial of service attack. TUF's security model labels this type of vulnerability an "Endless data attack," and can lead to verification failing to complete and disrupting services that rely on sigstore-go for verification. The vulnerable loops are in the verification functions in the package `github.com/sigstore/sigstore-go/pkg/verify`. The first is the DSSE envelope verification loop in `verifyEnvelopeWithArtifact`, which decodes all the digests in an attestation can be found here: https://github.com/sigstore/sigstore-go/blob/725e508ed4933e6f5b5206e32af4bbe76f587b54/pkg/verify/...
