CVE-2015-5261
HighSummary
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.
Risk Assessment
This vulnerability may lead to unauthorized access to host memory, posing a serious threat to the integrity and confidentiality of data within the organization.
Recommendation
It is recommended to update SPICE to version 0.12.6 or later to mitigate this vulnerability.
Other vulnerabilities in SPICE
See all- CVE-2017-7506High
Spice versions through 0.13 are vulnerable to out-of-bounds memory access when processing specially crafted messages from authenticated attacker to the spice server, resulting in crash and/or server memory leak.
- CVE-2016-2150High
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.
- CVE-2015-5260High
Heap-based buffer overflow in SPICE before 0.12.6 allows guest OS users to cause a denial of service or possibly execute arbitrary code on the host via QXL commands related to the surface_id parameter.
- CVE-2016-0749Critical
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.
