FreeBSD : jackson-core -- denial of service (6a9d0f14-cf3d-11f1-a655-3497f65b111b)

high Nessus Plugin ID 370454

Synopsis

The remote FreeBSD host is missing one or more security-related updates.

Description

The version of FreeBSD installed on the remote host is prior to tested version. It is, therefore, affected by multiple vulnerabilities as referenced in the 6a9d0f14-cf3d-11f1-a655-3497f65b111b advisory.

The Jackson project reports:
CVE-2026-89407: NumberInput.looksLikeValidNumber() pre-validates stringified numbers with PATTERN_FLOAT, whose adjacent quantifiers allow catastrophic backtracking on crafted input.
CVE-2026-89425: UTF8DataInputJsonParser builds the offending token text for an error message in a loop without an upper bound, so it ignores maxErrorTokenLength. The other three parser implementations are not affected.

Tenable has extracted the preceding description block directly from the FreeBSD security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Update the affected packages.
