Descriptions

The bs_worker code in open build service before 20170320 followed relative symlinks, allowing reading of files outside of the package source directory during build, allowing leakage of private information.

El código bs_worker en open build service, anterior a 20170320, seguía symlinks relativos, lo que permitía la lectura de archivos fuera del directorio origen del paquete durante la build. Esto permitía el filtrado de información privada.
