Amazon Linux 2 : tomcat (ALAS-2025-2953)

high Nessus Plugin ID 243425

Language:

Synopsis

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

Description

The version of tomcat installed on the remote host is prior to 7.0.76-10. It is, therefore, affected by a vulnerability as referenced in the ALAS2-2025-2953 advisory.

 For some unlikely configurations of multipart upload, an Integer Overflow vulnerability in Apache Tomcat could lead to a DoS via bypassing of size limits.

 This issue affects Apache Tomcat: from 11.0.0-M1 through 11.0.8, from 10.1.0-M1 through 10.1.42, from 9.0.0.M1 through 9.0.106.

 Users are recommended to upgrade to version 11.0.9, 10.1.43 or 9.0.107, which fix the issue.
 (CVE-2025-52520)

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 tomcat' to update your system.
