    Arch Linux Security Advisory ASA-202102-25
    Severity: High
    Date    : 2021-02-12
    CVE-ID  : CVE-2021-0326
    Package : wpa_supplicant
    Type    : arbitrary code execution
    Remote  : Yes
    Link    :
    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.
