This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Flexera Software Flexnet License Server Manager. Authentication is not required to exploit this vulnerability.
The flaw exists within the lmadmin and lmgrd components which listen by default on TCP port 27000 (this can vary however if the port is in use). When handling a packet type having the opcode 0x2f the process trusts a user provided value when calculating the bytes remaining in the packet. Using this tainted remaining length value the process then copies packet data into a buffer on the heap. A remote attacker can exploit this vulnerability to execute arbitrary code under the context of the lmadmin user.
