Summary
Package updates are available for Amazon Linux 2023 that fix the following vulnerabilities: CVE-2026-29786: node-tar is a full-featured Tar for Node.js. Prior to version 7.5.10, tar can be tricked into creating a hardlink that points outside the extraction directory by using a drive-relative link target such as C:../target.txt, which enables file overwrite outside cwd during normal tar.x() extraction. This issue has been patched in version 7.5.10. CVE-2026-27171: A flaw was found in zlib. An attacker providing specially crafted input to the crc32_combine64 or crc32_combine_gen64 functions could trigger an infinite loop within the x2nmodp function. This leads to excessive CPU consumption, which can result in a Denial of Service (DoS) for the affected system. CVE-2026-25547: @isaacs/brace-expansion is a hybrid CJS/ESM TypeScript fork of brace-expansion. Prior to version 5.0.1, @isaacs/brace-expansion is vulnerable to a denial of service (DoS) issue caused by unbounded brace range expansion. When an attacker provides a pattern containing repeated numeric brace ranges, the library attempts to eagerly generate every possible combination synchronously. Because the expansion grows exponentially, even a small input can consume excessive CPU and memory and may crash the Node.js process. This issue has been patched in version 5.0.1.
