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-2023-38703 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-2023-38703/ (Markdown: https://insights.sbomify.com/CVE-2023-38703/index.md)","id":"CVE-2023-38703","markdown":"https://insights.sbomify.com/CVE-2023-38703/index.md","name":"CVE-2023-38703","record":{"aliases":["ALPINE-CVE-2023-38703","DEBIAN-CVE-2023-38703","GHSA-f76w-fh7c-pc66","UBUNTU-CVE-2023-38703"],"analysis":{"component_type":"library","fix_type":"patch","impacts":["code_execution","denial_of_service"],"network_reachable":"yes","non_default_config":true,"product_category":"PJSIP multimedia library","requires_auth":"none","summary":"Attackers can trigger a use-after-free in PJSIP SRTP transport, potentially causing application crashes or arbitrary code execution.","user_interaction":"not_required","vuln_class":"use_after_free"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"pjsip","vendor":"teluu"}],"cvss":{"score":9.8,"severity":"critical","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-416","name":"Use After Free"}],"description":"PJSIP is a free and open source multimedia communication library written in C with high level API in C, C++, Java, C#, and Python languages. SRTP is a higher level media transport which is stacked upon a lower level media transport such as UDP and ICE. Currently a higher level transport is not synchronized with its lower level transport that may introduce use-after-free issue. This vulnerability affects applications that have SRTP capability (`PJMEDIA_HAS_SRTP` is set) and use underlying media transport other than UDP. This vulnerability’s impact may range from unexpected application termination to control flow hijack/memory corruption. The patch is available as a commit in the master branch.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"PJSIP has use-after-free vulnerability in SRTP media transport","id":"CVE-2023-38703","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"use_after_free","year":"2023"},"n_packages":0,"n_references":3,"next":{"headline":"import-in-the-middle allows unsanitized user controlled input in module generation","id":"CVE-2023-38704"},"packages":[],"prev":{"headline":"Knowage Server vulnerable to path traversal via upload functionality","id":"CVE-2023-38702"},"products":["pjproject"],"published":"2023-10-06","related":[{"cvss_score":9.1,"headline":"Media transport downgrade from the secure version (SRTP) to non-secure (RTP) in pjsip","id":"CVE-2022-39269","kev_date_added":null,"published":"2022-10-06"},{"cvss_score":8.8,"headline":"PJSIP: Stack overflow handling Service-Route headers in a registration response","id":"CVE-2026-57161","kev_date_added":null,"published":"2026-09-04"},{"cvss_score":8.8,"headline":"PJSIP: Stack overflow parsing SDP a=crypto attributes","id":"CVE-2026-57162","kev_date_added":null,"published":"2026-09-04"},{"cvss_score":8.8,"headline":"PJSIP: Stack overflow parsing a TLS peer certificate's SubjectAltName in GnuTLS backend","id":"CVE-2026-57163","kev_date_added":null,"published":"2026-09-04"},{"cvss_score":8.4,"headline":"PJSIP: SDP parser out-of-bounds write in remote payload-type map maintenance","id":"CVE-2026-57159","kev_date_added":null,"published":"2026-09-04"},{"cvss_score":8.3,"headline":"PJSIP: Heap overflow in the HTTP client","id":"CVE-2026-57164","kev_date_added":null,"published":"2026-09-04"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"yes","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2025-02-13","vendors":["pjsip"]},"summary":"Attackers can trigger a use-after-free in PJSIP SRTP transport, potentially causing application crashes or arbitrary code execution.","url":"https://insights.sbomify.com/CVE-2023-38703/"}
