CVE-2020-28491 affects jackson-dataformat-cbor with unchecked allocation of byte buffers causing OutOfMemoryError. The target repository (version 2.21.4-tuxcare.1) contains the upstream fix that was introduced in version 2.11.4 by commit de072d314. The fix limits immediate allocation to 250k bytes (LONGEST_NON_CHUNKED_BINARY constant) and uses incremental reading via _finishLongContiguousBytes() for larger declared lengths. This prevents memory exhaustion from malicious CBOR data claiming huge lengths with minimal actual data. The fix was authored by upstream maintainer Tatu Saloranta (tatu.saloranta@iki.fi) and shipped in the upstream release before TuxCare onboarded version 2.21.4.\n\nAdvisory cross-check (dlmn): outside the affected ranges of GitHub (>= 2.8.0rc1, < 2.11.4; >= 2.12.0rc1, < 2.12.1), NVD (< 2.11.4; > 2.12.0, < 2.12.1; = 2.12.0; = 2.12.0-rc1; = 2.12.0-rc2), cve.org (< 2.11.4; >= 2.12.0-rc1, < 2.12.1), Snyk (>= 0, < 2.11.4; >= 2.12.0-rc1, < 2.12.1).",
