Security Bulletin
This security bulletin contains information about 3 vulnerabilities.
EUVDB-ID: #VU28948
Risk: Medium
CVSSv3.1: 7.4 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:H/E:P/RL:O/RC:C]
CVE-ID: CVE-2020-12695
CWE-ID:
CWE-20 - Improper input validation
Exploit availability: Yes
DescriptionThe vulnerability allows a remote attacker to perform a distributed denial of service (DDoS) attack.
The vulnerability exists due to a CallStranger issue in the UPnP SUBSCRIBE functionality. A remote attacker can send traffic to arbitrary destinations, leading to amplified DDoS attacks and data exfiltration.
MitigationUpdate wpa package to version 2:2.7+git20190128+0c1e29f-6+deb10u3.
Vulnerable software versionsDebian Linux: All versions
wpa (Debian package): before 2:2.7+git20190128+0c1e29f-6+deb10u3

EUVDB-ID: #VU59104
Risk: Medium
CVSSv3.1: 6.7 [CVSS:3.1/AV:A/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H/E:P/RL:O/RC:C]
CVE-ID: CVE-2021-0326
CWE-ID:
CWE-787 - Out-of-bounds write
Exploit availability: Yes
DescriptionThe vulnerability allows a remote attacker to compromise vulnerable system.
The vulnerability exists due to a boundary error when processing untrusted input within the p2p_copy_client_info() function of p2p.c in wpa_suplicant. A remote attacker pass specially crafted input to the application, trigger out-of-bounds write and execute arbitrary code on the target system.
MitigationUpdate wpa package to version 2:2.7+git20190128+0c1e29f-6+deb10u3.
