CVE-2023-27478 Information

Description

libmemcached-awesome is an open source C/C++ client library and tools for the memcached server. libmemcached could return data for a previously requested key if that previous request timed out due to a low POLL_TIMEOUT. This issue has been addressed in version 1.1.4. Users are advised to upgrade. There are several ways to workaround or lower the probability of this bug affecting a given deployment. 1: use a reasonably high POLL_TIMEOUT setting like the default. 2: use separate libmemcached connections for unrelated data. 3: do not re-use libmemcached connections in an unknown state.
