Security Bulletin
This security bulletin contains information about 2 vulnerabilities.
1) Memory corruption
EUVDB-ID: #VU6658
Risk: Low
CVSSv4.0: 5.9 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear]
CVE-ID: CVE-2017-7294
CWE-ID:
CWE-119 - Memory corruption
Exploit availability: No
DescriptionThe vulnerability allows a local attacker to cause DoS condition or gain elevated privileges on the target system.
The weakness exists in the vmw_surface_define_ioctl function in drivers/gpu/drm/vmwgfx/vmwgfx_surface.c due to missing validation of addition of certain levels data. A local attacker can trigger integer overflow and out-of-bounds write, cause the service to crash or possibly gain root privileges via a crafted ioctl call for a /dev/dri/renderD* device.
Update the affected packages.
Linux kernel: 4.10 - 4.10.5

Q & A
Can this vulnerability be exploited remotely?
No. This vulnerability can be exploited locally. The attacker should have authentication credentials and successfully authenticate on the system.
Is there known malware, which exploits this vulnerability?
No. We are not aware of malware exploiting this vulnerability.
2) Heap-out-of-bounds write
EUVDB-ID: #VU6526
Risk: Low
CVSSv4.0: 6.8 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:A/U:Clear]
CVE-ID: CVE-2017-7308
CWE-ID:
CWE-787 - Out-of-bounds write
Exploit availability: Yes
DescriptionThe vulnerability allows a local attacker to cause DoS conditions.
The weakness exists due to improper validation of certain block-size data by the packet_set_ring function in net/packet/af_packet.c. A local attacker can provide specific parameters to the PACKET_RX_RING option on an AF_PACKET socket with a TPACKET_V3 ring buffer version enabled, trigger heap-out-of-bounds write and cause denial of service.
Successful exploitation of the vulnerability results in denial of service.
Update the affected packages.
Linux kernel: 4.0.1 - 4.10.6
