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)

Tenable has extracted the preceding description block directly from the tested product 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

Run 'yum update bcel' to update your system.
