FreeBSD : jackson-core -- StreamReadConstraints can be bypassed (0cb42b4a-9f19-11f1-a655-3497f65b111b)

critical Nessus Plugin ID 339071

Language:

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 a vulnerability as referenced in the 0cb42b4a-9f19-11f1-a655-3497f65b111b advisory.

The Jackson project reports:
Enforce maxNameLength incrementally in ReaderBasedJsonParser Fail parsing from DataInput if StreamReadConstraints.getMaxDocumentLength() set Fix maxDocumentLength bypass in async parser single feedInput() case Enforce StreamReadConstraints.maxNumberLength for non-blocking (async) parser UTF8DataInputJsonParser needs to enforce StreamReadConstraints.maxNameLength limit

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

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

Solution

Update the affected packages.
