Rated medium severity (CVSS 6.6), this vulnerability is remotely exploitable, low attack complexity. This Buffer Copy without Size Check vulnerability could allow attackers to overflow a buffer to corrupt adjacent memory.

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. Rated high severity (CVSS 7.5), this vulnerability is no authentication required. No vendor patch available.

Multiple integer overflow and buffer overflow issues were discovered in spice-client's handling of LZ compressed frames. Rated high severity (CVSS 8.8), this vulnerability is remotely exploitable, low attack complexity.

A vulnerability was discovered in SPICE before version 0.14.1 where the generated code used for demarshalling messages lacked sufficient bounds checks. Rated high severity (CVSS 8.8), this vulnerability is remotely exploitable, low attack complexity. This Buffer Overflow vulnerability could allow attackers to corrupt memory to execute arbitrary code or crash the application.

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. Rated high severity (CVSS 8.8), this vulnerability is remotely exploitable, low attack complexity. No vendor patch available.

SPICE allows local guest OS users to read from or write to arbitrary host memory locations via crafted primary surface parameters, a similar issue to CVE-2015-5261. Rated high severity (CVSS 7.1), this vulnerability is low attack complexity. No vendor patch available.

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,. Rated critical severity (CVSS 9.8), this vulnerability is remotely exploitable, no authentication required, low attack complexity. Epss exploitation probability 16.0% and no vendor patch available.

Heap-based buffer overflow in SPICE before 0.12.6 allows guest OS users to read and write to arbitrary memory locations on the host via guest QXL commands related to surface creation. Rated high severity (CVSS 7.1), this vulnerability is low attack complexity. No vendor patch available.

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. Rated high severity (CVSS 7.8), this vulnerability is low attack complexity. No vendor patch available.

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. Rated medium severity (CVSS 6.9). No vendor patch available.

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. Rated medium severity (CVSS 5.0), this vulnerability is remotely exploitable, low attack complexity. Public exploit code available and no vendor patch available.

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. Rated medium severity (CVSS 5.0), this vulnerability is remotely exploitable, low attack complexity.
