Amazon Linux 2 : golang (ALAS-2023-2037)

high Nessus Plugin ID 175947

Language:

Synopsis

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

Description

The version of golang installed on the remote host is prior to 1.18.9-1. It is, therefore, affected by a vulnerability as referenced in the ALAS2-2023-2037 advisory.

 HTTP and MIME header parsing could allocate large amounts of memory, even when parsing small inputs.

 Certain unusual patterns of input data could cause the common function used to parse HTTP and MIME headers to allocate substantially more memory than required to hold the parsed headers. An attacker can exploit this behavior to cause an HTTP server to allocate large amounts of memory from a small request, potentially leading to memory exhaustion and a denial of service. (CVE-2023-24534)

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 golang' to update your system.
