Amazon Linux 2 : xmlrpc-c (ALAS-2022-1795)

critical Nessus Plugin ID 161457

Language:

Synopsis

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

Description

The version of xmlrpc-c installed on the remote host is prior to 1.32.5-1905.svn2451. It is, therefore, affected by a vulnerability as referenced in the ALAS2-2022-1795 advisory.

 A flaw was found in expat. Passing malformed 2- and 3-byte UTF-8 sequences (for example, from start tag names) to the XML processing application on top of expat can lead to arbitrary code execution. This issue is dependent on how invalid UTF-8 is handled inside the XML processor. (CVE-2022-25235)

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 xmlrpc-c' to update your system.
