A DoS tool might make it easier for remote attackers to cause a denial of service (CPU consumption) by performing many renegotiations within a single connection.https://patchthecve.com/cve/CVE-2020-14355.htmlhttps://patchthecve.com/cve/CVE-2020-14355.htmlWed, 17 Jun 2026 02:54:36 +0000MEDIUM 6.6: 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 messagehttps://patchthecve.com/cve/CVE-2019-3813.htmlhttps://patchthecve.com/cve/CVE-2019-3813.htmlWed, 17 Jun 2026 02:35:38 +0000HIGH 7.5: 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.https://patchthecve.com/cve/CVE-2018-10893.htmlhttps://patchthecve.com/cve/CVE-2018-10893.htmlWed, 17 Jun 2026 01:34:51 +0000HIGH 7.6: Multiple integer overflow and buffer overflow issues were discovered in spice-client's handling of LZ compressed frames. A malicious server could cause the client to crash or, potentially, execute arbitrary code.https://patchthecve.com/cve/CVE-2018-10873.htmlhttps://patchthecve.com/cve/CVE-2018-10873.htmlWed, 17 Jun 2026 01:34:48 +0000HIGH 8.3: 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,https://patchthecve.com/cve/CVE-2016-9578.htmlhttps://patchthecve.com/cve/CVE-2016-9578.htmlWed, 17 Jun 2026 00:56:16 +0000HIGH 7.5: A vulnerability was discovered in SPICE before 0.13.90 in the server's protocol handling. An attacker able to connect to the SPICE server could send crafted messages which would cause the process to crash.https://patchthecve.com/cve/CVE-2016-9577.htmlhttps://patchthecve.com/cve/CVE-2016-9577.htmlWed, 17 Jun 2026 00:56:16 +0000HIGH 7.5: A vulnerability was discovered in SPICE before 0.13.90 in the server's protocol handling. An authenticated attacker could send crafted messages to the SPICE server causing a heap overflow leading to a crash or possible code execution.https://patchthecve.com/cve/CVE-2017-7506.htmlhttps://patchthecve.com/cve/CVE-2017-7506.htmlWed, 17 Jun 2026 01:24:29 +0000HIGH 8.8: 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.https://patchthecve.com/cve/CVE-2015-3247.htmlhttps://patchthecve.com/cve/CVE-2015-3247.htmlWed, 17 Jun 2026 00:25:36 +0000MEDIUM 6.9: 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.https://patchthecve.com/cve/CVE-2013-4282.htmlhttps://patchthecve.com/cve/CVE-2013-4282.htmlTue, 16 Jun 2026 23:56:56 +0000MEDIUM 5.0: 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.https://patchthecve.com/cve/CVE-2013-4130.htmlhttps://patchthecve.com/cve/CVE-2013-4130.htmlTue, 16 Jun 2026 23:56:40 +0000MEDIUM 5.0: 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.
