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-2026-57160 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-2026-57160/ (Markdown: https://insights.sbomify.com/CVE-2026-57160/index.md)","id":"CVE-2026-57160","markdown":"https://insights.sbomify.com/CVE-2026-57160/index.md","name":"CVE-2026-57160","record":{"aliases":["DEBIAN-CVE-2026-57160","GHSA-277r-3q2j-mxcw","UBUNTU-CVE-2026-57160"],"analysis":{"component_type":"library","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"PJSIP SIP library","requires_auth":"none","summary":"A buffer overflow in PJSIP allows remote attackers to write one byte past the buffer end, potentially causing crashes in SIP proxies or SBCs.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"pjsip","vendor":"teluu"}],"cvss":{"score":6.9,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:L/VA:L/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-193","name":"Off-by-one Error"}],"description":"PJSIP is a free and open source multimedia communication library written in C. Prior to commit d6a0e7f, a buffer overflow can occur in pjsip_generic_array_hdr_print() in pjsip/src/pjsip/sip_msg.c, the function that serializes generic array headers (such as Allow, Require, Supported, and Unsupported). Under certain output-buffer boundary conditions the function can write one byte past the end of the buffer. This is reachable mainly in applications that parse and re-serialize incoming SIP requests — for example a proxy, SBC, or B2BUA — where a remote peer can influence the serialized message. The out-of-bounds write is a single fixed byte; code execution and information disclosure are not demonstrated, and in typical pool-based allocations the byte falls within allocation slack. This issue has been patched via commit d6a0e7f.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":false,"headline":"PJSIP: SIP message header buffer overflow","id":"CVE-2026-57160","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"memory_corruption","year":"2026"},"n_packages":0,"n_references":2,"next":{"headline":"PJSIP: Stack overflow handling Service-Route headers in a registration response","id":"CVE-2026-57161"},"packages":[],"prev":{"headline":"PJSIP: SDP parser out-of-bounds write in remote payload-type map maintenance","id":"CVE-2026-57159"},"products":["pjproject"],"published":"2026-09-04","related":[{"cvss_score":9.8,"headline":"PJSIP has use-after-free vulnerability in SRTP media transport","id":"CVE-2023-38703","kev_date_added":null,"published":"2023-10-06"},{"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":"partial"},"state":"PUBLISHED","updated":"2026-09-08","vendors":["pjsip"]},"summary":"A buffer overflow in PJSIP allows remote attackers to write one byte past the buffer end, potentially causing crashes in SIP proxies or SBCs.","url":"https://insights.sbomify.com/CVE-2026-57160/"}
