Exploitation vector: Network

Description

The vulnerability allows a remote attacker to cause DoS condition on the target system.

The weakness exists due to boundary error in the process_bin_delete function when running in verbose mode. A remote attacker can cause the service to crash via a request to delete a key, which does not account for the lack of a null terminator in the key and triggers buffer over-read when printing to stderr.

Mitigation
Update to version 1.4.17.

Vulnerable software versions

memcached: 1.4.0 - 1.4.16
