FreeBSD : PostgreSQL -- PostgreSQL GB18030 encoding validation can read one byte past end of allocation for text that fails validation (78b8e808-2c45-11f0-9a65-6cc21735f730)

medium Nessus Plugin ID 235670

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 78b8e808-2c45-11f0-9a65-6cc21735f730 advisory.

 PostgreSQL project reports:

 A buffer over-read in PostgreSQL GB18030 encoding validation allows a database input provider to achieve temporary denial of service on platforms where a 1-byte over-read can elicit process termination. This affects the database server and also libpq. Versions before PostgreSQL 17.5, 16.9, 15.13, 14.18, and 13.21 are affected.


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.
