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 can allocate large amounts of memory, even when parsing small inputs, potentially leading to a denial of service. Certain unusual patterns of input data can 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.
 With fix, header parsing now correctly allocates only the memory required to hold parsed headers.
 (CVE-2023-24534)

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.
