Debian Security Advisory DSA 4450-1 (wpa - security update)
Published: 2019-05-25 02:00:04
CVE Author: NIST National Vulnerability Database
CVSS Base Vector:
AV:N/AC:M/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-4450-1 advisory.
Detection Method:
Checks if a vulnerable Linux Distribution Package version is present on the target host.
Technical Details:
A vulnerability was found in the WPA protocol implementation found in
wpa_supplication (station) and hostapd (access point).
The EAP-pwd implementation in hostapd (EAP server) and wpa_supplicant (EAP
peer) doesn't properly validate fragmentation reassembly state when receiving
an unexpected fragment. This could lead to a process crash due to a NULL
pointer derefrence.
An attacker in radio range of a station or access point with EAP-pwd support
could cause a crash of the relevant process (wpa_supplicant or hostapd),
ensuring a denial of service.
Affected Versions:
'wpa' Linux Distribution Package(s) on Debian Linux.
Recommendations:
For the stable distribution (stretch), this problem has been fixed in
version 2:2.4-1+deb9u4.
We recommend that you upgrade your wpa Linux Distribution Packages.
Solution Type:
Vendor Patch
Detection Type:
Linux Distribution Package

What's vulnerability management?
Vulnerability management is the process in which vulnerabilities in IT are identified and the risks of these vulnerabilities are evaluated. This evaluation leads to correcting the vulnerabilities and removing the risk or a formal risk acceptance by the management of an organization. The term vulnerability management is often confused with vulnerability scanning. Despite the fact both are related, there is an important difference between the two. Vulnerability scanning consists of using a computer program to identify vulnerabilities in networks, computer infrastructure or applications. Vulnerability management is the process surrounding vulnerability scanning, also taking into account other aspects such as risk acceptance, remediation etc. Source: "Implementing a Vulnerability Management Process".
