Package : memcached
Version : 1.5.6-1.1+deb10u1
CVE ID : CVE-2022-48571

It was discovered that there was a potential Denial of Service (DoS)
vulnerability in memcached, a high-performance in-memory object
caching system.

A crash could have occured when handling "multi-packet" uploads in
UDP mode. Deployments of memcached that only use TCP are likely
unaffected by this issue.

For Debian 10 buster, this problem has been fixed in version
1.5.6-1.1+deb10u1.

We recommend that you upgrade your memcached packages.
