CVE-2013-4130 – spice: unsafe clients ring access abort

https://notcve.org/view.php?id=CVE-2013-4130

The (1) red_channel_pipes_add_type and (2) red_channel_pipes_add_empty_msg functions in server/red_channel.c in SPICE before 0.12.4 do not properly perform ring loops, which might allow remote attackers to cause a denial of service (reachable assertion and server exit) by triggering a network error. Las funciones (1) red_channel_pipes_add_type y (2) red_channel_pipes_add_empty_msg ein server/red_channel.c en SPICE before 0.12.4, no realizan bucles en anillo adecuadamente, lo que podría permitir a atacantes remotos realizar una denegación de servicio (aserción alcanzable y salida del servidor) mediante un mensaje de error de red. • http://cgit.freedesktop.org/spice/spice/commit/?id=53488f0275d6c8a121af49f7ac817d09ce68090d http://rhn.redhat.com/errata/RHSA-2013-1260.html http://seclists.org/oss-sec/2013/q3/115 http://www.debian.org/security/2014/dsa-2839 http://www.ubuntu.com/usn/USN-1926-1 https://bugzilla.redhat.com/show_bug.cgi?id=984769 https://access.redhat.com/security/cve/CVE-2013-4130 • CWE-399: Resource Management Errors •
