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-2026-32945 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-2026-32945/ (Markdown: https://insights.sbomify.com/CVE-2026-32945/index.md)","id":"CVE-2026-32945","markdown":"https://insights.sbomify.com/CVE-2026-32945/index.md","name":"CVE-2026-32945","record":{"aliases":["ALPINE-CVE-2026-32945","DEBIAN-CVE-2026-32945","GHSA-jr2p-p2w4-rr9q","UBUNTU-CVE-2026-32945"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["code_execution","denial_of_service"],"network_reachable":"yes","non_default_config":true,"product_category":"PJSIP multimedia library","requires_auth":"none","summary":"Heap-based buffer overflow in PJSIP's DNS parser allows attackers to execute code or cause denial of service in applications using the built-in resolver.","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":8.4,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:H/AT:N/PR:N/UI:N/VC:H/VI:L/VA:H/SC:N/SI:N/SA:N","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. Versions 2.16 and below have a Heap-based Buffer Overflowvulnerability in the DNS parser's name length handler. Thisimpacts applications using PJSIP's built-in DNS resolver, such as those configured with pjsua_config.nameserver or UaConfig.nameserver in PJSUA/PJSUA2. It does not affect users who rely on the OS resolver (e.g., getaddrinfo()) by not configuring a nameserver, or those using an external resolver via pjsip_resolver_set_ext_resolver(). This issue is fixed in version 2.17. For users unable to upgrade, a workaround is to disable DNS resolution in the PJSIP config (by setting nameserver_count to zero) or to use an external resolver implementation instead.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":"2026-04-06","github_poc":1,"max_poc_stars":0,"metasploit":0,"nuclei":0,"refs":[{"date":"2026-04-06T17:33:19Z","kind":"github_poc","ref":"https://github.com/JohannesLks/CVE-2026-32945","stars":0,"title":"PJSIP DNS Compression Pointer Heap OOB Read (Remote DoS)"}],"tier":"poc_unverified"},"has_fix":true,"headline":"PJSIP is vulnerable to Heap-based Buffer Overflow through DNS parser","id":"CVE-2026-32945","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":"Egress Policy Bypass via DNS over TCP in Harden-Runner (Community Tier)","id":"CVE-2026-32946"},"packages":[],"prev":{"headline":"Parse Server crash via deeply nested query condition operators","id":"CVE-2026-32944"},"products":["pjproject"],"published":"2026-03-20","related":[{"cvss_score":8.7,"headline":"PJSIP: Heap use-after-free in PJSIP presence subscription termination handler","id":"CVE-2026-28799","kev_date_added":null,"published":"2026-03-06"},{"cvss_score":8.7,"headline":"PJSIP: Stack buffer overflow in Opus codec parser","id":"CVE-2026-29068","kev_date_added":null,"published":"2026-03-06"},{"cvss_score":8.5,"headline":"PJSIP: Heap buffer overflow in Opus codec decoding","id":"CVE-2026-40614","kev_date_added":null,"published":"2026-04-21"},{"cvss_score":8.1,"headline":"PJSIP: Stack buffer overflow in pjsip_auth_create_digest2()","id":"CVE-2026-40892","kev_date_added":null,"published":"2026-04-21"},{"cvss_score":8.1,"headline":"PJSIP has a Heap-based Buffer Overflow vulnerability in its H.264 unpacketizer","id":"CVE-2026-26967","kev_date_added":null,"published":"2026-02-20"},{"cvss_score":8.1,"headline":"PJSIP has a heap buffer overflow in ICE with long username","id":"CVE-2026-25994","kev_date_added":null,"published":"2026-02-11"}],"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)"},{"class":"open","licence":"CC0","name":"PoC-in-GitHub"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-03-20","vendors":["pjsip"]},"summary":"Heap-based buffer overflow in PJSIP's DNS parser allows attackers to execute code or cause denial of service in applications using the built-in resolver.","url":"https://insights.sbomify.com/CVE-2026-32945/"}
