Spice Project SPICE 0.5.3

spice versions though 0.13 are vulnerable to out-of-bounds memory access when processing specially crafted messages from authenticated attacker to the spice server resulting into crash and/or server memory leak.

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.
