Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2023-49295 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- github.com/quic-go/quic-go (Go): affected all versions; fixed in 0.37.7, 0.38.2, 0.39.4, 0.40.1\n- github.com/quic-go/quic-go (Go): affected all versions; fixed in 0.37.7\n- github.com/quic-go/quic-go (Go): affected all versions; fixed in 0.37.7\n- github.com/quic-go/quic-go (Go): affected from 0.38.0; fixed in 0.38.2\n- github.com/quic-go/quic-go (Go): affected from 0.38.0; fixed in 0.38.2\n- github.com/quic-go/quic-go (Go): affected from 0.39.0; fixed in 0.39.4\n- github.com/quic-go/quic-go (Go): affected from 0.39.0; fixed in 0.39.4\n- github.com/quic-go/quic-go (Go): affected from 0.40.0; fixed in 0.40.1\n- github.com/quic-go/quic-go (Go): affected from 0.40.0; fixed in 0.40.1\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2023-49295/ (Markdown: https://insights.sbomify.com/CVE-2023-49295/index.md)","id":"CVE-2023-49295","markdown":"https://insights.sbomify.com/CVE-2023-49295/index.md","name":"CVE-2023-49295","record":{"aliases":["AZL-33285","AZL-34627","DEBIAN-CVE-2023-49295","GHSA-ppxx-5m9h-6vxf","GO-2024-2459","RHSA-2024:0855","UBUNTU-CVE-2023-49295","openSUSE-SU-2024:13570-1","openSUSE-SU-2025:14626-1"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Go QUIC library","requires_auth":"low_privilege","summary":"An attacker can exhaust memory in quic-go by sending excessive PATH_CHALLENGE frames, causing a denial of service.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"quic-go","vendor":"quic-go_project"}],"cvss":{"score":6.4,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:L/I:L/A:H","version":"3.1"},"cwes":[{"id":"CWE-400","name":"Uncontrolled Resource Consumption"}],"description":"quic-go is an implementation of the QUIC protocol (RFC 9000, RFC 9001, RFC 9002) in Go.

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.
