Security Bulletin
This security bulletin contains information about 2 vulnerabilities.
EUVDB-ID: #VU8002
Risk: Low
CVSSv3.1: 7 [CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H/E:P/RL:O/RC:C]
CVE-ID: CVE-2017-1000371
CWE-ID:
CWE-264 - Permissions, Privileges, and Access Controls
Exploit availability: Yes
DescriptionThe vulnerability allows a local attacker to bypass security restrictions on the target system.
The weakness exists due to a flaw in offset2lib patch. A local attacker
can send a specially-crafted request, bypass security restrictions and
gain full access to the system.
Install updates from vendor's website.

EUVDB-ID: #VU22595
Risk: Medium
CVSSv3.1: 7.7 [CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C]
CVE-ID: CVE-2019-17666
CWE-ID:
CWE-119 - Memory corruption
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error within the P2P (Wifi-Direct) functionality in rtl_p2p_noa_ie() function in drivers/net/wireless/realtek/rtlwifi/ps.c in Linux kernel when processing Notice and Absence frames. A remote attacker can send specially crafted data via the wireless network, trigger memory corruption and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
MitigationInstall updates from vendor's website.
