AIX (IJ37226)

medium Nessus Plugin ID 158516

Language:

Synopsis

The remote AIX host is missing a security patch.

Description

The version of AIX installed on the remote host is prior to APAR IJ37226. It is, therefore, affected by a vulnerability as referenced in the IJ37226 advisory.

 - In BIND 9.3.0 -> 9.11.35, 9.12.0 -> 9.16.21, and versions 9.9.3-S1 -> 9.11.35-S1 and 9.16.8-S1 -> 9.16.21-S1 of BIND Supported Preview Edition, as well as release versions 9.17.0 -> 9.17.18 of the BIND 9.17 development branch, exploitation of broken authoritative servers using a flaw in response processing can cause degradation in BIND resolver performance. The way the lame cache is currently designed makes it possible for its internal data structures to grow almost infinitely, which may cause significant delays in client query processing. (CVE-2021-25219)

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

Solution

Please apply the appropriate interim fix per APAR IJ37226.
