CVE-2015-3247

spice: memory corruption in worker_update_monitors_config()

Race condition in the worker_update_monitors_config function in SPICE 0.12.4 allows a remote authenticated guest user to cause a denial of service (heap-based memory corruption and QEMU-KVM crash) or possibly execute arbitrary code on the host via unspecified vectors.

CVE-2015-5260

spice: insufficient validation of surface_id parameter can cause crash

Heap-based buffer overflow in SPICE before 0.12.6 allows guest OS users to cause a denial of service (heap-based memory corruption and QEMU-KVM crash) or possibly execute arbitrary code on the host via QXL commands related to the surface_id parameter.

CVE-2016-0749

spice: heap-based memory corruption within smartcard handling

The smartcard interaction in SPICE allows remote attackers to cause a denial of service (QEMU-KVM process crash) or possibly execute arbitrary code via vectors related to connecting to a guest VM, which triggers a heap-based buffer overflow.

CVE-2013-4282

spice: stack buffer overflow in reds_handle_ticket() function

Stack-based buffer overflow in the reds_handle_ticket function in server/reds.c in SPICE 0.12.0 allows remote attackers to cause a denial of service (crash) via a long password in a SPICE ticket.

spice: unsafe clients ring access abort

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.

CVE-2020-14355

spice: multiple buffer overflow vulnerabilities in QUIC decoding code

Multiple buffer overflow vulnerabilities were found in the QUIC image decoding process of the SPICE remote display system, before spice-0.14.2-1. Both the SPICE client (spice-gtk) and server are affected by these flaws. These flaws allow a malicious client or server to send specially crafted messages that, when processed by the QUIC image compression algorithm, result in a process crash or potential code execution.

CVE-2019-3813

spice: Off-by-one error in array access in spice/server/memslot.c

Spice, versions 0.5.2 through 0.14.1, are vulnerable to an out-of-bounds read due to an off-by-one error in memslot_get_virt. This may lead to a denial of service, or, in the worst case, code-execution by unauthenticated attackers.

spice: Missing check in demarshal.py:write_validate_array_item() allows for buffer overflow and denial of service

A vulnerability was discovered in SPICE before version 0.14.1 where the generated code used for demarshalling messages lacked sufficient bounds checks. A malicious client or server, after authentication, could send specially crafted messages to its peer which would result in a crash or, potentially, other impacts.
