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-2011-1147 in the wild and no public exploit code.\n\nAffected product: Digium Asterisk. 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-2011-1147/ (Markdown: https://insights.sbomify.com/CVE-2011-1147/index.md)","id":"CVE-2011-1147","markdown":"https://insights.sbomify.com/CVE-2011-1147/index.md","name":"CVE-2011-1147","record":{"aliases":["DEBIAN-CVE-2011-1147","GHSA-747x-cf7f-hf5f"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["denial_of_service","code_execution"],"network_reachable":"yes","non_default_config":true,"product_category":"Asterisk PBX","requires_auth":"none","summary":"Remote attackers can cause a crash or execute arbitrary code via crafted UDPTL packets in Asterisk when T.38 support is enabled.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"redhat","cpe":[{"product":"asterisk","vendor":"digium"},{"product":"asterisknow","vendor":"digium"},{"product":"s800i","vendor":"digium"}],"cvss":{"score":6.8,"severity":"medium","source":"nvd","vector":"AV:N/AC:M/Au:N/C:P/I:P/A:P","version":"2.0"},"cwes":[{"id":"CWE-119","name":"Improper Restriction of Operations within the Bounds of a Memory Buffer"}],"description":"Multiple stack-based and heap-based buffer overflows in the (1) decode_open_type and (2) udptl_rx_packet functions in main/udptl.c in Asterisk Open Source 1.4.x before 1.4.39.2, 1.6.1.x before 1.6.1.22, 1.6.2.x before 1.6.2.16.2, and 1.8 before 1.8.2.4; Business Edition C.x.x before C.3.6.3; AsteriskNOW 1.5; and s800i (Asterisk Appliance), when T.38 support is enabled, allow remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via a crafted UDPTL packet.","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":"Memory corruption in n/a","id":"CVE-2011-1147","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"digium:asterisk","products":["digium:asterisk"],"type":"memory_corruption","year":"2011"},"n_packages":0,"n_references":12,"next":{"headline":"Use after free in n/a","id":"CVE-2011-1148"},"packages":[],"prev":{"headline":"Missing authorization in n/a","id":"CVE-2011-1146"},"products":["n/a"],"published":"2011-03-15","related":[{"cvss_score":9.8,"headline":"Command injection in n/a","id":"CVE-2017-14100","kev_date_added":null,"published":"2017-09-02"},{"cvss_score":9,"headline":"Privilege escalation in n/a","id":"CVE-2014-8418","kev_date_added":null,"published":"2014-11-24"},{"cvss_score":9,"headline":"Missing authorization in n/a","id":"CVE-2011-1599","kev_date_added":null,"published":"2011-04-27"},{"cvss_score":8.8,"headline":"Memory corruption in n/a","id":"CVE-2017-16671","kev_date_added":null,"published":"2017-11-09"},{"cvss_score":8.8,"headline":"Memory corruption in n/a","id":"CVE-2017-7617","kev_date_added":null,"published":"2017-04-10"},{"cvss_score":7.8,"headline":"Denial of service in n/a","id":"CVE-2009-2726","kev_date_added":null,"published":"2009-08-12"},{"cvss_score":7.8,"headline":"Null dereference in n/a","id":"CVE-2007-1306","kev_date_added":null,"published":"2007-03-07"}],"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":"2024-08-06","vendors":["n/a"]},"summary":"Remote attackers can cause a crash or execute arbitrary code via crafted UDPTL packets in Asterisk when T.38 support is enabled.","url":"https://insights.sbomify.com/CVE-2011-1147/"}
