"The following CVE(s) have been reported against src:wpa.

CVE-2019-10064

hostapd before 2.6, in EAP mode, makes calls to the rand() and
random() standard library functions without any preceding srand() or
srandom() call, which results in inappropriate use of deterministic
values. This was fixed in conjunction with CVE-2016-10743.

CVE-2020-12695

The Open Connectivity Foundation UPnP specification before 2020-04-17
does not forbid the acceptance of a subscription request with a
delivery URL on a different network segment than the fully qualified
event-subscription URL, aka the CallStranger issue.

For Debian 9 stretch, these problems have been fixed in version
2:2.4-1+deb9u7.

We recommend that you upgrade your wpa packages.

For the detailed security status of wpa please refer to its security
tracker page at: https://security-tracker.debian.org/tracker/wpa

block directly from the DLA security advisory. Tenable has attempted
