high Nessus Plugin ID 135937

Language:

Synopsis

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

Description

The version of icu installed on the remote host is prior to 50.2-4.0. It is, therefore, affected by a vulnerability as referenced in the ALAS-2020-1361 advisory.

 An issue was discovered in International Components for Unicode (ICU) for C/C++ through 66.1. An integer overflow, leading to a heap-based buffer overflow, exists in the UnicodeString::doAppend() function in common/unistr.cpp. (CVE-2020-10531)

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 icu' to update your system.
