CVE-2020-28491 is NOT present in jackson-dataformat-cbor 2.18.5-tuxcare.2. The vulnerability involved unchecked allocation of byte buffers based on attacker-controlled CBOR length fields, which could cause OutOfMemoryError. The upstream fix (commit de072d314af8) is present in the target, having shipped in the upstream release 2.18.5. The fix adds a 250,000-byte threshold check before allocation and uses incremental reading (ByteArrayBuilder) for larger declared lengths, preventing eager allocation of arbitrarily large buffers.\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).",
