It was found that RPM wrote file contents to the target installation directory under a temporary name, and verified its cryptographic signature only after the temporary file has been written completely. Under certain conditions, the system interprets the unverified temporary file contents and extracts commands from it. This could allow an attacker to modify signed RPM files in such a way that they would execute code chosen by the attacker during package installation.
