Amazon Linux 2 : libxslt (ALAS-2025-2966)

high Nessus Plugin ID 252300

Language:

Synopsis

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

Description

The version of libxslt installed on the remote host is prior to 1.1.28-6. It is, therefore, affected by a vulnerability as referenced in the ALAS2-2025-2966 advisory.

 A flaw was found in the libxslt library. The same memory field, psvi, is used for both stylesheet and input data, which can lead to type confusion during XML transformations. This vulnerability allows an attacker to crash the application or corrupt memory. In some cases, it may lead to denial of service or unexpected behavior. (CVE-2025-7424)

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 libxslt' to update your system.
