FreeBSD : Erlang/OTP -- heap corruption decoding invalidly encoded large tuples (445df078-89e1-11f1-b35c-4c526214c986)

medium Nessus Plugin ID 330266

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 445df078-89e1-11f1-b35c-4c526214c986 advisory.

 The Erlang/OTP team reports:
 Fixed heap corruption when an invalidly encoded tuple with an arity of 2^31 or larger is decoded from Erlang's External Term Format (binary_to_term).

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.
