CVE-2020-10931 [HIGH] CWE-121 memcached: mishandled memcpy into a stack-based buffer may lead to DoS
memcached: mishandled memcpy into a stack-based buffer may lead to DoS
Memcached 1.6.x before 1.6.2 allows remote attackers to cause a denial of service (daemon crash) via a crafted binary protocol header to try_read_command_binary in memcached.c.
A buffer overflow flaw was found in memcached 1.6.0, due to not having a mechanism to verify the length of “extlen” when calling the memcpy function if a large value is assigned to the “extlen” variable. This flaw causes a denial of service and presents a significant risk to system availability.
Statement: This issue did not affect the versions of memcached as shipped with Red Hat Enterprise Linux 6, 7, and 8 as they did not include the vulnerable code.

CVE-2020-10931 memcached: mishandled memcpy into a stack-based buffer may lead to DoS
There is no mechanism to verify the length of "extlen" when calling memcpy function, It will cause buffer overflow if large value is assigned to the extlen variable. This may result in DoS.
