Alpine: nomad: security update to 1.5.3-r0

critical Tenable Cloud Security Plugin ID 405870

Description

There are packages installed that are affected by multiple vulnerabilities referenced in the following CVEs:

 - HashiCorp Nomad and Nomad Enterprise versions 1.5.0 up to 1.5.2 allow unauthenticated users to bypass
 intended ACL authorizations for clusters where mTLS is not enabled. This issue is fixed in version 1.5.3.
 (CVE-2023-1782)

 - 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)
