Comment 7 Ramon de C Valle 2012-01-26 17:06:56 UTC 
A numeric range comparison without minimum check flaw was found within headerVerifyInfo function of RPM library. This function is used by rpm utility to verify the values of header structures (i.e. signature and header sections) of a RPM file. An attacker could create a specially-crafted RPM file that, when read, could cause RPM to crash or, potentially, execute arbitrary code.
