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-2011-0753 in the wild and no public exploit code.\n\nAffected product: Php Php. 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-2011-0753/ (Markdown: https://insights.sbomify.com/CVE-2011-0753/index.md)","id":"CVE-2011-0753","markdown":"https://insights.sbomify.com/CVE-2011-0753/index.md","name":"CVE-2011-0753","record":{"aliases":["GHSA-qmj6-6gg3-prp7"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":true,"product_category":"PHP PCNTL extension","requires_auth":"none","summary":"Attackers can cause denial of service via memory corruption in PHP's PCNTL extension when concurrent signals are sent to a user-defined signal handler.","user_interaction":"not_required","vuln_class":"race_condition"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"php","vendor":"php"}],"cvss":{"score":4.3,"severity":"medium","source":"nvd","vector":"AV:N/AC:M/Au:N/C:N/I:N/A:P","version":"2.0"},"cwes":[{"id":"CWE-362","name":"Concurrent Execution using Shared Resource with Improper Synchronization"}],"description":"Race condition in the PCNTL extension in PHP before 5.3.4, when a user-defined signal handler exists, might allow context-dependent attackers to cause a denial of service (memory corruption) via a large number of concurrent signals.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":null,"headline":"Race condition in n/a","id":"CVE-2011-0753","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"php:php","products":["php:php"],"type":"race_condition","year":"2011"},"n_packages":0,"n_references":4,"next":{"headline":"Path traversal in n/a","id":"CVE-2011-0754"},"packages":[],"prev":{"headline":"Other in n/a","id":"CVE-2011-0752"},"products":["n/a"],"published":"2011-02-02","related":[{"cvss_score":10,"headline":"Integer overflow in n/a","id":"CVE-2012-2688","kev_date_added":null,"published":"2012-07-20"},{"cvss_score":10,"headline":"Memory corruption in n/a","id":"CVE-2012-2376","kev_date_added":null,"published":"2012-05-21"},{"cvss_score":10,"headline":"Memory corruption in n/a","id":"CVE-2011-3268","kev_date_added":null,"published":"2011-08-25"},{"cvss_score":10,"headline":"Other in n/a","id":"CVE-2009-4143","kev_date_added":null,"published":"2009-12-21"},{"cvss_score":10,"headline":"Memory corruption in n/a","id":"CVE-2008-5557","kev_date_added":null,"published":"2008-12-23"},{"cvss_score":10,"headline":"Memory corruption in n/a","id":"CVE-2008-2050","kev_date_added":null,"published":"2008-05-05"},{"cvss_score":10,"headline":"Command injection in n/a","id":"CVE-2008-2051","kev_date_added":null,"published":"2008-05-05"}],"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":"Attackers can cause denial of service via memory corruption in PHP's PCNTL extension when concurrent signals are sent to a user-defined signal handler.","url":"https://insights.sbomify.com/CVE-2011-0753/"}
