Name of the Vulnerable Software and Affected Versions memcached versions 1.6.x before 1.6.2

Description The issue allows remote attackers to cause a denial of service, resulting in a daemon crash. This is achieved by sending a crafted binary protocol header to the try read command binary function in memcached.c.

Recommendations For memcached versions 1.6.x before 1.6.2, update to version 1.6.2 or later to resolve the issue. As a temporary workaround, consider restricting access to the try read command binary function in memcached.c to minimize the risk of exploitation.
