"details": "It was discovered that wpa_supplicant and hostapd were vulnerable to a\nside channel attack against EAP-pwd. A remote attacker could possibly use\nthis issue to recover certain passwords. (CVE-2019-9495)\n\nMathy Vanhoef discovered that wpa_supplicant and hostapd incorrectly\nvalidated received scalar and element values in EAP-pwd-Commit messages. A\nremote attacker could possibly use this issue to perform a reflection\nattack and authenticate without the appropriate password. (CVE-2019-9497,\nCVE-2019-9498, CVE-2019-9499)\n\nIt was discovered that hostapd incorrectly handled obtaining random\nnumbers. In rare cases where the urandom device isn't available, it would\nfall back to using a low-quality PRNG. This issue only affected Ubuntu\n14.04 LTS and Ubuntu 16.04 LTS. (CVE-2016-10743)\n",
