It can only be exploited from the same machine or local network, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2022-0324 and fix it if it is affected.\n\nWhat it is: CVE-2022-0324 is a high-severity memory corruption vulnerability in Linux Foundation Software for Open Networking in the Cloud (SONiC), published on 14 Nov 2022. It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2022-0324 in the wild and no public exploit code.\n\nAffected product: Linux Foundation Software for Open Networking in the Cloud (SONiC). No package-level version data is available, so check the vendor advisory linked from the reference page.\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-2022-0324/ (Markdown: https://insights.sbomify.com/CVE-2022-0324/index.md)","id":"CVE-2022-0324","markdown":"https://insights.sbomify.com/CVE-2022-0324/index.md","name":"CVE-2022-0324","record":{"aliases":["GHSA-cq4f-m4r6-7827"],"analysis":{"component_type":"network_device","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"SONiC network OS","requires_auth":"none","summary":"Remote attackers can crash the DHCPv6 relay service via crafted packets, causing denial of service in SONiC network devices.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GovTech CSG","cpe":[{"product":"software_for_open_networking_in_the_cloud","vendor":"linuxfoundation"}],"cvss":{"score":8.1,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-787","name":"Out-of-bounds Write"},{"id":"CWE-120","name":"Buffer Copy without Checking Size of Input"}],"description":"There is a vulnerability in DHCPv6 packet parsing code that could be explored by remote attacker to craft a packet that could cause buffer overflow in a memcpy call, leading to out-of-bounds memory write that would cause dhcp6relay to crash.
