PGP Desktop 10.0.x before 10.0.3 SP2 and 10.1.0 before 10.1.0 SP1 does not properly implement the "Decrypt/Verify File via Right-Click" functionality for multi-packet OpenPGP messages that represent multi-message input, which allows remote attackers to spoof signed data by concatenating an additional message to the end of a legitimately signed message, related to a "piggy-back" or "unsigned data injection" issue. PGP Desktop v10.0.x anterior a v10.0.3 SP2 y v10.1.0 anterior a v10.1.0 SP1 no implementa adecuadamente la funcionalidad "Descifrar/Verificar archivo a través de Clic-Derecho" para mensajes OpenPGP multi-empaquetados que representan entradas multi-mensaje, lo que premite a atacantes remotos falsear datos firmados concatenando un mensaje adicional al final del mensaje firmado legitimamente, relacionado con un fallo "piggy-back" o "inyección de datos sin firmar". • http://secunia.com/advisories/42293 http://secunia.com/advisories/42307 http://www.cs.ru.nl/E.Verheul/papers/Govcert/Pretty%20Good%20Piggybagging%20v1.0.pdf http://www.kb.cert.org/vuls/id/300785 http://www.securitytracker.com/id?1024760 http://www.symantec.com/security_response/securityupdates/detail.jsp?fid=security_advisory&pvid=security_advisory&year=2010&suid=20101118_00 https://exchange.xforce.ibmcloud.com/vulnerabilities/63366 https://pgp.custhelp.com/app/answers/detail/a_id/2290 • CWE-310: Cryptographic Issues •
