CVE-2011-1564 is a vulnerability of currently unknown severity. Multiple integer overflows in the HMI application in DATAC RealFlex RealWin 2.1 (Build 6.1.10.10) and earlier allow remote attackers to execute arbitrary code via crafted (1) On_FC_MISC_FCS_MSGBROADCAST and (2) On_FC_MISC_FCS_MSGSEND packets, which trigger a heap-based buffer overflow.. EPSS estimates a 18.63% chance of exploitation in the next 30 days.
