Description
PackagePersister.validate_tgz builds "tar -tf #{tgz} 2>&1" where tgz = File.join(release_dir, 'packages', "#{name}.tgz") and name = package_meta['name'] comes directly from release.MF inside the uploaded tarball. The string is passed to Bosh::Common::Exec.sh, which executes via %x{} — i.e., /bin/sh -c. No Shellwords.escape is applied. The Models::Package Sequel validation (VALID_ID = /^[-0-9A-Za-z_+.]+$/i) would reject the name, but in create_package (lines 74–79) the shell-out in save_package_source_blob runs before package.save, so validation fires too late.
Affected versions:
- BOSH: all versions prior to v282.1.12 (inclusive); fixed in v282.1.12 or later

Title: BOSH de Cloud Foundry Foundation, Description: PackagePersister.validate_tgz construye 'tar -tf #{tgz} 2>&1' donde tgz = File.join(release_dir, 'packages', '#{name}.tgz') y name = package_meta['name'] proviene directamente de release.MF dentro del tarball subido. La cadena se pasa a Bosh::Common::Exec.sh, que se ejecuta a través de %x{} - es decir, /bin/sh -c. No se aplica Shellwords.escape. La validación de Sequel de Models::Package (VALID_ID = /^[-0-9A-Za-z_+.]+$/i) rechazaría el nombre, pero en create_package (líneas 74-79) la ejecución de comandos externos en save_package_source_blob se ejecuta antes de package.save, por lo que la validación se activa demasiado tarde.
Versiones afectadas:
- BOSH: todas las versiones anteriores a la v282.1.12 (inclusive); corregido en la v282.1.12 o posterior
