CVE-2017-10983 - log back

CVE-2017-10983 created at 25 Sep 2019 19:31:40
Severity	+ Medium
Remote	+ Remote
Type	+ Denial of service
Description	+ A security issue has been found in freeradius <= 3.0.15, where the fr_dhcp_decode() function performed a strcmp() on binary data in an internal data structure, instead of checking the length of the option and doing a memcmp. A remote attacker with the ability to send packets which are accepted by the server can make the server read its memory until it reaches a zero byte or crashes, causing a denial of service.
