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/ALBA-2020-3657/ (Markdown: https://insights.sbomify.com/ALBA-2020-3657/index.md)","id":"ALBA-2020:3657","markdown":"https://insights.sbomify.com/ALBA-2020-3657/index.md","name":"ALBA-2020:3657","record":{"aliases":[],"analysis":{"component_type":"library","fix_type":"patch","impacts":["other"],"network_reachable":"unknown","non_default_config":false,"product_category":"zlib compression library","requires_auth":"none","summary":"Bug fixes for zlib on s390x architecture address incomplete raw stream generation and hardware acceleration issues, ensuring data integrity.","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":"The zlib packages provide a general-purpose lossless data compression\nlibrary that is used by many different programs.\n\nBug Fix(es) and Enhancement(s):\n\n* AlmaLinux8.2 - zlib on s390x may produce incomplete raw (but not gzip/zlib)\nstreams (BZ#1860952)\n\n* AlmaLinux8.2 - raw zlib test failed with DFLTCC_LEVEL_MASK set to 0x1ff\n(BZ#1862108)\n\n* AlmaLinux8.2 - Fix support for IBM Z hardware-accelerated deflate (zlib)\n(BZ#1867876)","ecosystems":["AlmaLinux:8"],"exploits":{"exploitdb":null,"first_seen":null,"github_poc":null,"max_poc_stars":null,"metasploit":null,"nuclei":null,"refs":[],"tier":null},"has_fix":true,"headline":"zlib bug fix and enhancement update","id":"ALBA-2020:3657","indexable":true,"kev":null,"kind":"advisory","links":{"ecosystem":null,"product":null,"products":[],"type":"other","year":"2020"},"n_packages":1,"n_references":null,"packages":[{"ecosystem":"AlmaLinux:8","fixed":["1.2.11-16.el8_2"],"introduced":["0"],"last_affected":[],"package":"zlib-static","purl":"pkg:rpm/almalinux/zlib-static","source":"ALBA-2020:3657"}],"products":null,"published":"2020-09-08","related":[],"sources":[{"class":"attribution","licence":"MIT","name":"AlmaLinux","prefix":"ALBA"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":null,"updated":null,"vendors":null},"summary":"Bug fixes for zlib on s390x architecture address incomplete raw stream generation and hardware acceleration issues, ensuring data integrity.","url":"https://insights.sbomify.com/ALBA-2020-3657/"}
