Arch Linux Security Advisory ASA-202102-25
Date : 2021-02-12
CVE-ID : CVE-2021-0326
Package : wpa_supplicant
Type : arbitrary code execution
Remote : Yes
Link : https://security.archlinux.org/AVG-1530
The package wpa_supplicant before version 2:2.9-8 is vulnerable to
arbitrary code execution.
Upgrade to 2:2.9-8.
# pacman -Syu "wpa_supplicant>=2:2.9-8"
The problem has been fixed upstream but no release is available yet.
The issue can be mitigated by disabling P2P, using the control
interface command "P2P_SET disabled 1" or "p2p_disabled=1" in (each, if
multiple interfaces used) wpa_supplicant configuration file.
A security issue was found in hostapd and wpa_supplicant version 2.9. A
missing length check in the p2p_copy_client_info function could lead to
a buffer overflow.
An attacker within radio range of the device running P2P discovery
might be able to cause a crash or execute arbitrary code.
