CVSS v3 Base Score: 7.5 | Impact Score: 3.6 | Exploitability Score: 3.9

VMScore: 0

An infinite loop vulnerability was found in Samba's mdssvc RPC service for Spotlight. When parsing Spotlight mdssvc RPC packets sent by the client, the core unmarshalling function sl_unpack_loop() did not validate a field in the network packet that contains the count of elements in an array-like structure. By passing 0 as the count value, the attacked function will run in an endless loop consuming 100% CPU. This flaw allows an malicious user to issue a malformed RPC request, triggering an infinite loop, resulting in a denial of service condition.
