Summary

Red Hat Security Advisory: Red Hat Ansible Automation Platform 2.4 Product Security and Bug Fix Update

Severity

Moderate

Notes

Topic: An update is now available for Red Hat Ansible Automation Platform 2.4 Red Hat Product Security has rated this update as having a security impact of Moderate. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.

Details: Red Hat Ansible Automation Platform provides an enterprise framework for building, deploying and managing IT automation at scale. IT Managers can provide top-down guidelines on how automation is applied to individual teams, while automation developers retain the freedom to write tasks that leverage existing knowledge without the overhead. Ansible Automation Platform makes it possible for users across an organization to share, vet, and manage automation content by means of a simple, powerful, and agentless language. Security Fix(es): * receptor: quic-go: memory exhaustion attack against QUIC's path validation mechanism (CVE-2023-49295) For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section. Additional changes: * receptor has been updated to 1.4.4

CVE-2023-49295

A memory exhaustion vulnerability was found in Quic-GO, where a malicious client exploits the path validation mechanism to induce the server into accumulating an unbounded queue of PATH_RESPONSE frames, depleting its memory. The attacker controls the victim's packet send rate by overwhelming the server with numerous packets containing PATH_CHALLENGE frames. Through selective acknowledgments of received packets and manipulation of peer's Round-Trip Time (RTT) estimates, the attacker induces congestion control mechanisms to reduce the server's send rate significantly. Consequently, the victim server is compelled to store an increasing number of queued PATH_RESPONSE frames, resulting in memory exhaustion.

6.5 (Medium)

The attacker controls the victim\u0027s packet send rate by overwhelming the server with numerous packets containing PATH_CHALLENGE frames. Through selective acknowledgments of received packets and manipulation of peer\u0027s Round-Trip Time (RTT) estimates, the attacker induces congestion control mechanisms to reduce the server\u0027s send rate significantly. Consequently, the victim server is compelled to store an increasing number of queued PATH_RESPONSE frames, resulting in memory exhaustion.",

CVE-2023-49295 (GCVE-0-2023-49295)

Vulnerability from cvelistv5 – Published: 2024-01-10 21:40 – Updated: 2025-06-17 20:59

Title

quic-go's path validation mechanism can cause denial of service

Summary

quic-go is an implementation of the QUIC protocol (RFC 9000, RFC 9001, RFC 9002) in Go. An attacker can cause its peer to run out of memory sending a large number of PATH_CHALLENGE frames. The receiver is supposed to respond to each PATH_CHALLENGE frame with a PATH_RESPONSE frame. The attacker can prevent the receiver from sending out (the vast majority of) these PATH_RESPONSE frames by collapsing the peers congestion window (by selectively acknowledging received packets) and by manipulating the peer's RTT estimate. This vulnerability has been patched in versions 0.37.7, 0.38.2 and 0.39.4.

Severity

6.4 (Medium)

The attacker can prevent the receiver from sending out (the vast majority of) these PATH_RESPONSE frames by collapsing the peers congestion window (by selectively acknowledging received packets) and by manipulating the peer\u0027s RTT estimate.

How durations are calculated

Following the VTEM framework (Black Hat USA 2015), time to patch starts when the vendor or a coordinator was informed, total time to patch at discovery, and disclosure to patch at public disclosure; vendor response time runs from the report to its acknowledgement. Time to exploit and time unpatched start at the earliest discovery or report, falling back to public disclosure. Unpatched time ends at the first recorded patch, or the calculation time when no patch is recorded. Exploitation to patch shows the interval between those two events; a published proof of concept is a public exploit, not exploitation.

Each result shows its source dates. A negative interval means the end event came first; when date-only inputs leave the order open, the result says so. Date-only inputs are approximate. The earliest evidence wins: KEV report dates and sightings are labelled as such. Records describing another vulnerability are listed but never calculated from, and a PoC alone does not establish exploitation. Missing patch evidence does not prove that no patch exists. Filters below change the event list only.

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
