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-2022-38153 in the wild and no public exploit code.\n\nAffected product: Wolfssl Wolfssl. 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-2022-38153/ (Markdown: https://insights.sbomify.com/CVE-2022-38153/index.md)","id":"CVE-2022-38153","markdown":"https://insights.sbomify.com/CVE-2022-38153/index.md","name":"CVE-2022-38153","record":{"aliases":["DEBIAN-CVE-2022-38153","GHSA-9cp4-7v5m-jx89","UBUNTU-CVE-2022-38153"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":true,"product_category":"TLS/SSL library","requires_auth":"none","summary":"A use-after-free vulnerability in wolfSSL allows attackers to crash TLS clients via large session tickets when session caching is enabled.","user_interaction":"not_required","vuln_class":"use_after_free"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"wolfssl","vendor":"wolfssl"}],"cvss":{"score":5.9,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-770","name":"Allocation of Resources Without Limits or Throttling"}],"description":"An issue was discovered in wolfSSL before 5.5.0 (when --enable-session-ticket is used); however, only version 5.3.0 is exploitable. Man-in-the-middle attackers or a malicious server can crash TLS 1.2 clients during a handshake. If an attacker injects a large ticket (more than 256 bytes) into a NewSessionTicket message in a TLS 1.2 handshake, and the client has a non-empty session cache, the session cache frees a pointer that points to unallocated memory, causing the client to crash with a \"free(): invalid pointer\" message. NOTE: It is likely that this is also exploitable during TLS 1.3 handshakes between a client and a malicious server. With TLS 1.3, it is not possible to exploit this as a man-in-the-middle.","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 n/a","id":"CVE-2022-38153","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"wolfssl:wolfssl","products":["wolfssl:wolfssl"],"type":"use_after_free","year":"2022"},"n_packages":0,"n_references":7,"next":{"headline":"Denial of service in n/a","id":"CVE-2022-38155"},"packages":[],"prev":{"headline":"Null dereference in n/a","id":"CVE-2022-38152"},"products":["n/a"],"published":"2022-08-31","related":[{"cvss_score":10,"headline":"Buffer overread in domain name matching","id":"CVE-2024-5991","kev_date_added":null,"published":"2024-08-27"},{"cvss_score":9.8,"headline":"Security feature bypass in n/a","id":"CVE-2021-37155","kev_date_added":null,"published":"2021-07-21"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2020-36177","kev_date_added":null,"published":"2021-01-06"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2014-2896","kev_date_added":null,"published":"2020-01-28"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2014-2897","kev_date_added":null,"published":"2020-01-28"},{"cvss_score":9.8,"headline":"Information disclosure in n/a","id":"CVE-2014-2898","kev_date_added":null,"published":"2020-01-28"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2019-16748","kev_date_added":null,"published":"2019-09-24"}],"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":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-03","vendors":["n/a"]},"summary":"A use-after-free vulnerability in wolfSSL allows attackers to crash TLS clients via large session tickets when session caching is enabled.","url":"https://insights.sbomify.com/CVE-2022-38153/"}
