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-2019-17178 in the wild and no public exploit code.\n\nAffected product: Freerdp Freerdp. 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-2019-17178/ (Markdown: https://insights.sbomify.com/CVE-2019-17178/index.md)","id":"CVE-2019-17178","markdown":"https://insights.sbomify.com/CVE-2019-17178/index.md","name":"CVE-2019-17178","record":{"aliases":["DEBIAN-CVE-2019-17178","GHSA-v77x-r3jc-52jh","UBUNTU-CVE-2019-17178"],"analysis":{"component_type":"library","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"PNG image library","requires_auth":"none","summary":"A memory leak in LodePNG allows attackers to cause denial of service via crafted PNG images due to improper realloc usage.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"freerdp","vendor":"freerdp"},{"product":"lodepng","vendor":"lodev"},{"product":"leap","vendor":"opensuse"}],"cvss":{"score":7.5,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-401","name":"Missing Release of Memory after Effective Lifetime"},{"id":"CWE-252","name":"Unchecked Return Value"}],"description":"HuffmanTree_makeFromFrequencies in lodepng.c in LodePNG through 2019-09-28, as used in WinPR in FreeRDP and other products, has a memory leak because a supplied realloc pointer (i.e., the first argument to realloc) is also used for a realloc return value.","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-2019-17178","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"freerdp:freerdp","products":["freerdp:freerdp","opensuse:leap"],"type":"memory_corruption","year":"2019"},"n_packages":0,"n_references":4,"next":{"headline":"Cross-site scripting in n/a","id":"CVE-2019-17179"},"packages":[],"prev":{"headline":"Denial of service in n/a","id":"CVE-2019-17177"},"products":["n/a"],"published":"2019-10-04","related":[{"cvss_score":9.8,"headline":"Other in n/a","id":"CVE-2021-37594","kev_date_added":null,"published":"2021-07-27"},{"cvss_score":9.8,"headline":"Other in n/a","id":"CVE-2021-37595","kev_date_added":null,"published":"2021-07-27"},{"cvss_score":9.4,"headline":"FreeRDP Windows Client before 3.29.0 Heap Buffer Overflow via Cliprdr","id":"CVE-2026-67305","kev_date_added":null,"published":"2026-08-01"},{"cvss_score":9.3,"headline":"FreeRDP before 3.29.0 TLS Certificate Identity Validation Bypass","id":"CVE-2026-66402","kev_date_added":null,"published":"2026-08-01"},{"cvss_score":9.3,"headline":"FreeRDP before 3.29.0 HTTP Proxy Request Injection via Redirection","id":"CVE-2026-67289","kev_date_added":null,"published":"2026-08-01"},{"cvss_score":9.3,"headline":"FreeRDP before 3.29.0 WebSocket Ping Buffer Over-disclosure","id":"CVE-2026-67292","kev_date_added":null,"published":"2026-08-01"},{"cvss_score":9.3,"headline":"FreeRDP before 3.29.0 Improper Certificate Hostname Validation","id":"CVE-2026-67293","kev_date_added":null,"published":"2026-08-01"}],"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":"2024-08-05","vendors":["n/a"]},"summary":"A memory leak in LodePNG allows attackers to cause denial of service via crafted PNG images due to improper realloc usage.","url":"https://insights.sbomify.com/CVE-2019-17178/"}
