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-2022-23608 in the wild and no public exploit code.\n\nAffected product: Debian Debian Linux. 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-2022-23608/ (Markdown: https://insights.sbomify.com/CVE-2022-23608/index.md)","id":"CVE-2022-23608","markdown":"https://insights.sbomify.com/CVE-2022-23608/index.md","name":"CVE-2022-23608","record":{"aliases":["ALPINE-CVE-2022-23608","DEBIAN-CVE-2022-23608","GHSA-ffff-m5fm-qm62","UBUNTU-CVE-2022-23608"],"analysis":{"component_type":"library","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"PJSIP multimedia library","requires_auth":"none","summary":"A use-after-free vulnerability in PJSIP can cause an endless loop and denial of service in dialog set scenarios.","user_interaction":"not_required","vuln_class":"use_after_free"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"certified_asterisk","vendor":"asterisk"},{"product":"debian_linux","vendor":"debian"},{"product":"asterisk","vendor":"sangoma"},{"product":"pjsip","vendor":"teluu"}],"cvss":{"score":8.1,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/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 language implementing standard based protocols such as SIP, SDP, RTP, STUN, TURN, and ICE. In versions up to and including 2.11.1 when in a dialog set (or forking) scenario, a hash key shared by multiple UAC dialogs can potentially be prematurely freed when one of the dialogs is destroyed . The issue may cause a dialog set to be registered in the hash table multiple times (with different hash keys) leading to undefined behavior such as dialog list collision which eventually leading to endless loop. A patch is available in commit db3235953baa56d2fb0e276ca510fefca751643f which will be included in the next release. There are no known workarounds for this issue.","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":"Use after free in PJSIP","id":"CVE-2022-23608","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"debian:debian_linux","products":["debian:debian_linux"],"type":"use_after_free","year":"2022"},"n_packages":0,"n_references":10,"next":{"headline":"Path traveresal in iTunesRPC-Remastered","id":"CVE-2022-23609"},"packages":[],"prev":{"headline":"Unsafe handling of user-specified cookies in treq","id":"CVE-2022-23607"},"products":["pjproject"],"published":"2022-02-22","related":[{"cvss_score":9.1,"headline":"Out-of-bounds read in multipart parsing in PJSIP","id":"CVE-2022-21723","kev_date_added":null,"published":"2022-01-27"},{"cvss_score":7.5,"headline":"Denial of service in n/a","id":"CVE-2017-9358","kev_date_added":null,"published":"2017-06-02"},{"cvss_score":7.3,"headline":"Potential integer underflow upon receiving STUN message in PJSIP","id":"CVE-2021-37706","kev_date_added":null,"published":"2021-12-22"},{"cvss_score":6.5,"headline":"Null dereference in n/a","id":"CVE-2021-46837","kev_date_added":null,"published":"2022-08-30"},{"cvss_score":6.5,"headline":"Denial of service in n/a","id":"CVE-2020-28242","kev_date_added":null,"published":"2020-11-06"},{"cvss_score":5,"headline":"Denial of service in n/a","id":"CVE-2013-2686","kev_date_added":null,"published":"2013-03-29"}],"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":"no","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2025-11-04","vendors":["pjsip"]},"summary":"A use-after-free vulnerability in PJSIP can cause an endless loop and denial of service in dialog set scenarios.","url":"https://insights.sbomify.com/CVE-2022-23608/"}
