No vendor fix yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for a patch.

Multiple buffer overflows in (1) lmgrd and (2) Vendor Daemon in Flexera FlexNet Publisher before 11.13.1.2 Security Update 1 allow remote attackers to execute arbitrary code via a crafted packet with opcode (a) 0x107 or (b) 0x10a.
