An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of PSF-2017-11 in the wild and no public exploit code.\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/PSF-2017-11/ (Markdown: https://insights.sbomify.com/PSF-2017-11/index.md)","id":"PSF-2017-11","markdown":"https://insights.sbomify.com/PSF-2017-11/index.md","name":"PSF-2017-11","record":{"aliases":[],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["code_execution","privilege_escalation"],"network_reachable":"yes","non_default_config":false,"product_category":"XML parsing library","requires_auth":"none","summary":"Expat library contains a DLL hijacking vulnerability on Windows allowing attackers to execute arbitrary code or escalate privileges.","user_interaction":"not_required","vuln_class":"other"},"analysis_generated_by":"qwen3.8-flash-next","assigner":null,"cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"Expat 2.2.2 was released with multiple security fixes:\n\n* #43: Protect against compilation without any source of high quality\n  entropy enabled, e.g. with CMake build system\n* #60: Windows with _UNICODE: Unintended use of LoadLibraryW with a non-wide\n  string resulted in failure to load advapi32.dll and degradation in quality\n  of used entropy when compiled with _UNICODE for Windows; you can launch\n  existing binaries with EXPAT_ENTROPY_DEBUG=1 in the environment to inspect\n  the quality of entropy used during runtime\n* [MOX-006]: Fix non-NULL parser parameter validation in XML_Parse; resulted\n  in NULL dereference, previously\n\nExpat 2.2.3 contains an additional security fix: #82: CVE-2017-11742 --\nWindows: Fix DLL hijacking vulnerability using Steve Holme's LoadLibrary\nwrapper for/of cURL","ecosystems":[],"exploits":{"exploitdb":null,"first_seen":null,"github_poc":null,"max_poc_stars":null,"metasploit":null,"nuclei":null,"refs":[],"tier":null},"has_fix":false,"headline":"Expat 2.2.3","id":"PSF-2017-11","indexable":true,"kev":null,"kind":"advisory","links":{"ecosystem":null,"product":null,"products":[],"type":"other","year":"2017"},"n_packages":0,"n_references":null,"packages":[],"products":null,"published":"2017-07-17","related":[],"sources":[{"class":"attribution","licence":"CC BY 4.0","name":"Python Software Foundation","prefix":"PSF"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":null,"updated":null,"vendors":null},"summary":"Expat library contains a DLL hijacking vulnerability on Windows allowing attackers to execute arbitrary code or escalate privileges.","url":"https://insights.sbomify.com/PSF-2017-11/"}
