About this tag
Memcached is a high-performance, distributed memory caching system commonly used in cloud and enterprise environments. On WindowsForum.com, discussions cover security vulnerabilities such as CVE-2026-47783 and CVE-2026-47784, which are timing side-channel flaws in SASL authentication fixed in version 1.6.42, and CVE-2023-46852 and CVE-2023-46853, which are buffer overflow and off-by-one errors in proxy mode fixed in 1.6.22. These CVEs affect Linux packages like Microsoft's Azure Linux 3.0, highlighting the importance of inventory and patching in hybrid Windows estates. Additionally, a case study details replacing Azure Redis with open-source Memcached to reduce costs and improve control in multi-region deployments.

    Memcached CVE-2023-46852: DoS risk in proxy mode and 1.6.22 fix

    The buffer-overflow flaw in Memcached that landed under CVE-2023-46852 is a deceptively small parser bug with outsized operational impact: malformed multiget requests containing many spaces after the "get" token can overflow internal buffers when Memcached is running in its optional proxy mode...
