A flaw was found in RPM’s signature check functionality when reading a
package file. This flaw allows an attacker who can convince a victim to
install a seemingly verifiable package, whose signature header was
modified, to cause RPM database corruption and execute code. The highest
threat from this vulnerability is to data integrity, confidentiality, and
system availability.
