CVE-2011-3493 is a vulnerability of currently unknown severity. Multiple stack-based buffer overflows in the DH_OneSecondTick function in Cogent DataHub 7.1.1.63 and earlier allow remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via long (1) domain, (2) report_domain, (3) register_datahub, or (4) slave commands.. EPSS estimates a 7.78% chance of exploitation in the next 30 days.
