This vulnerability has been modified since it was last analyzed by the NVD. It is awaiting reanalysis which may result in further changes to the information provided.
Description
Race condition in RPM 4.11.1 and earlier allows remote attackers to execute arbitrary code via a crafted RPM file whose installation extracts the contents to temporary files before validating the signature, as demonstrated by installing a file in the /etc/cron.d directory.

Description
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.
