Debian LTS Advisory ([SECURITY] [DLA 1922-1] wpa security update)

Technical Details

Severity Level:

Low Severity

CVSS Score:

3.3

CVSS Base Vector:
AV:A/AC:L/Au:N/C:N/I:N/A:P

Summary:
The remote host is missing an update for the 'wpa' Linux Distribution Package(s) announced via the DSA-1922-1 advisory.

Detection Method:
Checks if a vulnerable Linux Distribution Package version is present on the target host.

Technical Details:
hostapd (and wpa_supplicant when controlling AP mode) did not perform sufficient source address validation for some received Management frames and this could result in ending up sending a frame that caused associated stations to incorrectly believe they were disconnected from the network even if management frame protection (also known as PMF) was negotiated for the association. This could be considered to be a denial of service vulnerability since PMF is supposed to protect from this type of issues.

Affected Versions:
'wpa' Linux Distribution Package(s) on Debian Linux.

Recommendations:
For Debian 8 'Jessie', this problem has been fixed in version 2.3-1+deb8u9. We recommend that you upgrade your wpa Linux Distribution Packages.

Solution Type:
Vendor Patch

Detection Type:
Linux Distribution Package
