  "details" : [ "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.", "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." ],
  "statement" : "To exploit this flaw, an attacker must either compromise an RPM repository or convince an administrator to install an untrusted RPM.  It is strongly recommended to only use RPMs from trusted repositories.",
