Title
Junos OS: MX Series: PFE crash upon receipt of specific packet destined to an AMS interface
Summary
An Improper Handling of Exceptional Conditions vulnerability in packet processing of Juniper Networks Junos OS on MX Series allows an unauthenticated network-based attacker to send specific packets to an Aggregated Multiservices (AMS) interface on the device, causing the packet forwarding engine (PFE) to crash, resulting in a Denial of Service (DoS). Continued receipt and processing of this packet will create a sustained Denial of Service (DoS) condition.
This issue is only triggered by packets destined to a local-interface via a service-interface (AMS). AMS is only supported on the MS-MPC, MS-MIC, and MX-SPC3 cards. This issue is not experienced on other types of interfaces or configurations. Additionally, transit traffic does not trigger this issue.
This issue affects Juniper Networks Junos OS on MX Series:
All versions prior to 19.1R3-S10;
19.2 versions prior to 19.2R3-S7;
19.3 versions prior to 19.3R3-S8;

Title
Attacker controlled data in AST nodes is not validated in comrak
Summary
comrak is a CommonMark + GFM compatible Markdown parser and renderer written in rust. A Comrak AST can be constructed manually by a program instead of parsing a Markdown document with `parse_document`. This AST can then be converted to HTML via `html::format_document_with_plugins`. However, the HTML formatting code assumes that the AST is well-formed. For example, many AST notes contain `[u8]` fields which the formatting code assumes is valid UTF-8 data. Several bugs can be triggered if this is not the case. Version 0.17.0 contains adjustments to the AST, storing strings instead of unvalidated byte arrays. Users are advised to upgrade. Users unable to upgrade may manually validate UTF-8 correctness of all data when assigning to `&[u8]` and `Vec<u8>` fields in the AST. This issue is also tracked as `GHSL-2023-049`.

Title
`cilium-cli` disables etcd authorization for clustermesh clusters
Summary
`cilium-cli` is the command line interface to install, manage, and troubleshoot Kubernetes clusters running Cilium. Prior to version 0.13.2,`cilium-cli`, when used to configure cluster mesh functionality, can remove the enforcement of user permissions on the `etcd` store used to mirror local cluster information to remote clusters. Users who have set up cluster meshes using the Cilium Helm chart are not affected by this issue.
Due to an incorrect mount point specification, the settings specified by the `initContainer` that configures `etcd` users and their permissions are overwritten when using `cilium-cli` to configure a cluster mesh. An attacker who has already gained access to a valid key and certificate for an `etcd` cluster compromised in this manner could then modify state in that `etcd` cluster.
This issue is patched in `cilium-cli` 0.13.2. As a workaround, one may use Cilium's Helm charts to create their cluster.

Title
Cilium eBPF filters may be temporarily removed during agent restart
Summary
Cilium is a networking, observability, and security solution with an eBPF-based dataplane. In version 1.13.0, when Cilium is started, there is a short period when Cilium eBPF programs are not attached to the host. During this period, the host does not implement any of Cilium's featureset. This can cause disruption to newly established connections during this period due to the lack of Load Balancing, or can cause Network Policy bypass due to the lack of Network Policy enforcement during the window. This vulnerability impacts any Cilium-managed endpoints on the node (such as Kubernetes Pods), as well as the host network namespace (including Host Firewall). This vulnerability is fixed in Cilium 1.13.1 or later. Cilium releases 1.12.x, 1.11.x, and earlier are not affected. There are no known workarounds.

This can cause disruption to newly established connections during this period due to the lack of Load Balancing, or can cause Network Policy bypass due to the lack of Network Policy enforcement during the window. This vulnerability impacts any Cilium-managed endpoints on the node (such as Kubernetes Pods), as well as the host network namespace (including Host Firewall). This vulnerability is fixed in Cilium 1.13.1 or later. Cilium releases 1.12.x, 1.11.x, and earlier are not affected. There are no known workarounds."

Title
org.xwiki.platform:xwiki-platform-rendering-parser vulnerable to Improper Handling of Exceptional Conditions
Summary
XWiki Platform is a generic wiki platform. Starting in version 6.0, users with write rights can insert well-formed content that is not handled well by the parser. As a consequence, some pages becomes unusable, including the user index (if the page containing the faulty content is a user page) and the page index.
Note that on the page, the normal UI is completely missing and it is not possible to open the editor directly to revert the change as the stack overflow is already triggered while getting the title of the document. This means that it is quite difficult to remove this content once inserted.
This has been patched in XWiki 13.10.10, 14.4.6, and 14.9-rc-1. A temporary workaround to avoid Stack Overflow errors is to increase the memory allocated to the stack by using the `-Xss` JVM parameter (e.g., `-Xss32m`). This should allow the parser to pass and to fix the faulty content. The consequences for other aspects of the system (e.g., performance) are unknown, and this workaround should be only be used as a temporary solution. The workaround does not prevent the issue occurring again with other content. Consequently, it is strongly advised to upgrade to a version where the issue has been patched.

Title
Login fail open on JAAS misconfiguration in DataHub
Summary
DataHub is an open-source metadata platform. In the event a system is using Java Authentication and Authorization Service (JAAS) authentication and that system is given a configuration which contains an error, the authentication for the system will fail open and allow an attacker to login using any username and password. The reason for this is that while an error is thrown in the `authenticateJaasUser` method it is swallowed without propagating the error. As a result of this issue unauthenticated users may gain access to the system. Users are advised to upgrade. There are no known workarounds for this issue. This vulnerability was discovered and reported by the GitHub Security lab and is tracked as GHSL-2022-081.

"value": "DataHub is an open-source metadata platform. In the event a system is using Java Authentication and Authorization Service (JAAS) authentication and that system is given a configuration which contains an error, the authentication for the system will fail open and allow an attacker to login using any username and password. The reason for this is that while an error is thrown in the `authenticateJaasUser` method it is swallowed without propagating the error. As a result of this issue unauthenticated users may gain access to the system. Users are advised to upgrade. There are no known workarounds for this issue. This vulnerability was discovered and reported by the GitHub Security lab and is tracked as GHSL-2022-081."

Title
Junos OS: ACX2K Series: Receipt of a high rate of specific traffic will lead to a Denial of Service (DoS)
Summary
A vulnerability in class-of-service (CoS) queue management in Juniper Networks Junos OS on the ACX2K Series devices allows an unauthenticated network-based attacker to cause a Denial of Service (DoS). Specific packets are being incorrectly routed to a queue used for other high-priority traffic such as BGP, PIM, ICMP, ICMPV6 ND and ISAKMP. Due to this misclassification of traffic, receipt of a high rate of these specific packets will cause delays in the processing of other traffic, leading to a Denial of Service (DoS). Continued receipt of this amount of traffic will create a sustained Denial of Service (DoS) condition. This issue affects Juniper Networks Junos OS on ACX2K Series: All versions prior to 19.4R3-S9; All 20.2 versions; 20.3 versions prior to 20.3R3-S6 on ACX2K Series; 20.4 versions prior to 20.4R3-S4 on ACX2K Series; All 21.1 versions; 21.2 versions prior to 21.2R3-S3 on ACX2K Series. Note: This issues affects legacy ACX2K Series PPC-based devices. This platform reached Last Supported Version (LSV) as of the Junos OS 21.2 Release.
