Summary
memcached security update
Details

memcached is a high-performance, distributed memory object caching system, generic in nature, but intended for use in speeding up dynamic web applications by alleviating database load.

Security Fix(es):

In memcached before 1.6.42, username data for SASL password database authentication has a timing side channel because a loop exits as soon as a valid username is found by sasl_server_userdb_checkpass.(CVE-2026-47783)

In memcached before 1.6.42, password data for SASL password database authentication has a timing side channel because memcmp is used by sasl_server_userdb_checkpass.(CVE-2026-47784)
