Description Mauro Matteo Cascella 2020-08-12 16:47:35 UTC

Multiple buffer overflow vulnerabilities were found in the QUIC image decoding process of the SPICE remote display system. More specifically, these flaws reside in the spice-common shared code between the client and server of SPICE. In other words, both the client (spice-gtk) and server are affected by these flaws. A malicious client or server could send specially crafted messages which would result in a process crash or potential code execution.
