Amazon Linux 2 : amazon-ecr-credential-helper, --advisory ALAS2NITRO-ENCLAVES-2026-087 (ALASNITRO-ENCLAVES-2026-087)

critical Nessus Plugin ID 299554

Synopsis

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

Description

The version of amazon-ecr-credential-helper installed on the remote host is prior to 0.11.0-3. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2NITRO-ENCLAVES-2026-087 advisory.

 net/http: memory exhaustion in Request.ParseForm (CVE-2025-61726)

 archive/zip: denial of service when parsing arbitrary ZIP archives (CVE-2025-61728)

 crypto/tls: handshake messages may be processed at the incorrect encryption level (CVE-2025-61730)

 cmd/go: bypass of flag sanitization can lead to arbitrary code execution (CVE-2025-61731)

 cmd/go: unexpected code execution when invoking toolchain (CVE-2025-68119)

 crypto/tls: Config.Clone copies automatically generated session ticket keys, session resumption does not account for the expiration of full certificate chain (CVE-2025-68121)

Tenable has extracted the preceding description block directly from the tested product security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Run 'yum update amazon-ecr-credential-helper' or or 'yum update --advisory ALAS2NITRO-ENCLAVES-2026-087' to update your system.
