An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2011-1553 in the wild and no public exploit code.\n\nAffected product: Glyphandcog Xpdfreader. 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-2011-1553/ (Markdown: https://insights.sbomify.com/CVE-2011-1553/index.md)","id":"CVE-2011-1553","markdown":"https://insights.sbomify.com/CVE-2011-1553/index.md","name":"CVE-2011-1553","record":{"aliases":["DEBIAN-CVE-2011-1553","GHSA-6xpf-26gh-gvp9"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Type 1 font library","requires_auth":"none","summary":"Remote attackers can cause a denial of service via a crafted PDF document exploiting a use-after-free flaw in the t1lib library.","user_interaction":"required","vuln_class":"use_after_free"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"xpdf","vendor":"foolabs"},{"product":"xpdfreader","vendor":"glyphandcog"},{"product":"t1lib","vendor":"t1lib"}],"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-399","name":null}],"description":"Use-after-free vulnerability in t1lib 5.1.2 and earlier, as used in Xpdf before 3.02pl6, teTeX, and other products, allows remote attackers to cause a denial of service (application crash) via a PDF document containing a crafted Type 1 font that triggers an invalid memory write, a different vulnerability than CVE-2011-0764.","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-2011-1553","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"glyphandcog:xpdfreader","products":["glyphandcog:xpdfreader"],"type":"use_after_free","year":"2011"},"n_packages":0,"n_references":13,"next":{"headline":"Integer overflow in n/a","id":"CVE-2011-1554"},"packages":[],"prev":{"headline":"Memory corruption in n/a","id":"CVE-2011-1552"},"products":["n/a"],"published":"2011-03-31","related":[{"cvss_score":10,"headline":"Integer overflow in n/a","id":"CVE-2009-0165","kev_date_added":null,"published":"2009-04-23"},{"cvss_score":9.3,"headline":"Integer overflow in n/a","id":"CVE-2009-3603","kev_date_added":null,"published":"2009-10-21"},{"cvss_score":9.3,"headline":"Memory corruption in n/a","id":"CVE-2009-3604","kev_date_added":null,"published":"2009-10-21"},{"cvss_score":9.3,"headline":"Integer overflow in n/a","id":"CVE-2009-3606","kev_date_added":null,"published":"2009-10-21"},{"cvss_score":9.3,"headline":"Integer overflow in n/a","id":"CVE-2009-3608","kev_date_added":null,"published":"2009-10-21"},{"cvss_score":6.9,"headline":"Path traversal in n/a","id":"CVE-2009-1144","kev_date_added":null,"published":"2009-04-09"},{"cvss_score":6.8,"headline":"Memory corruption in n/a","id":"CVE-2011-0764","kev_date_added":null,"published":"2011-03-31"}],"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 denial of service via a crafted PDF document exploiting a use-after-free flaw in the t1lib library.","url":"https://insights.sbomify.com/CVE-2011-1553/"}
