An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-26967 in the wild and no public exploit code.\n\nAffected product: pjsip pjproject. 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-2026-26967/ (Markdown: https://insights.sbomify.com/CVE-2026-26967/index.md)","id":"CVE-2026-26967","markdown":"https://insights.sbomify.com/CVE-2026-26967/index.md","name":"CVE-2026-26967","record":{"aliases":["ALPINE-CVE-2026-26967","DEBIAN-CVE-2026-26967","GHSA-x2hc-6969-g8v6","UBUNTU-CVE-2026-26967"],"analysis":{"component_type":"library","fix_type":"patch","impacts":["code_execution","denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"PJSIP multimedia library","requires_auth":"none","summary":"Heap-based buffer overflow in PJSIP's H.264 unpacketizer allows attackers to execute code or cause denial of service via malformed SRTP packets.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"pjsip","vendor":"pjsip"}],"cvss":{"score":8.1,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U","version":"4.0"},"cwes":[{"id":"CWE-122","name":"Heap-based Buffer Overflow"}],"description":"PJSIP is a free and open source multimedia communication library written in C. In versions 2.16 and below, there is a critical Heap-based Buffer Overflow vulnerability in PJSIP's H.264 unpacketizer. The bug occurs when processing malformed SRTP packets, where the unpacketizer reads a 2-byte NAL unit size field without validating that both bytes are within the payload buffer bounds. The vulnerability affects applications that receive video using H.264.
