Amazon Linux 2 : bcel (ALAS-2023-1916)

critical Nessus Plugin ID 170439

Language:

Synopsis

The remote Amazon Linux 2 host is missing a security update.

Description

The version of bcel installed on the remote host is prior to 5.2-18. It is, therefore, affected by a vulnerability as referenced in the ALAS2-2023-1916 advisory.

 - Apache Commons BCEL has a number of APIs that would normally only allow changing specific class characteristics. However, due to an out-of-bounds writing issue, these APIs can be used to produce arbitrary bytecode. This could be abused in applications that pass attacker-controllable data to those APIs, giving the attacker more control over the resulting bytecode than otherwise expected. Update to Apache Commons BCEL 6.6.0. (CVE-2022-42920)

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

Solution

Run 'yum update bcel' to update your system.
