rad_decode in FreeRADIUS 0.9.2 and earlier allows remote attackers to cause a denial of service (crash) via a short RADIUS string attribute with a tag, which causes memcpy to be called with a -1 length argument, as demonstrated using the Tunnel-Password attribute. rad_decode en FreeRADIUS 0.9.2 y anteriores permite a atacantes remotos causar una denegación de servicio (caída) mediante una cadena de atributo RADIUS corta con una etiqueta, lo que hace se llame a memcpy con un argumento de longitud -1, como se ha demostrado usando el atributo "Tunnel-Password". • https://www.exploit-db.com/exploits/23391 http://marc.info/?l=bugtraq&m=106935911101493&w=2 http://marc.info/?l=bugtraq&m=106944220426970 http://marc.info/?l=freeradius-users&m=106947389449613&w=2 http://www.redhat.com/support/errata/RHSA-2003-386.html https://oval.cisecurity.org/repository/search/definition/oval%3Aorg.mitre.oval%3Adef%3A10917 https://access.redhat.com/security/cve/CVE-2003-0967 https://bugzilla.redhat.com/show_bug.cgi?id=1617109 •
