The Dell iDRAC6 with firmware 1.x before 1.92 and 2.x and 3.x before 3.42, and iDRAC7 with firmware before 1.23.23, allows remote attackers to bypass authentication and execute arbitrary IPMI commands by using cipher suite 0 (aka cipher zero) and an arbitrary password. NOTE: the vendor disputes the significance of this issue, stating "DRAC's are intended to be on a separate management network; they are not designed nor intended to be placed on or connected to the Internet."

The Supermicro BMC implementation allows remote attackers to bypass authentication and execute arbitrary IPMI commands by using cipher suite 0 (aka cipher zero) and an arbitrary password.

The HP Integrated Lights-Out (iLO) BMC implementation allows remote attackers to bypass authentication and execute arbitrary IPMI commands by using cipher suite 0 (aka cipher zero) and an arbitrary password.

Intel Enterprise Southbridge 2 Baseboard Management Controller (BMC), Intel Server Boards 5000XAL, S5000PAL, S5000PSL, S5000XVN, S5000VCL, S5000VSA, SC5400RA, and OEM Firmware for Intel Enterprise Southbridge Baseboard Management Controller before 20070119, when Intelligent Platform Management Interface (IPMI) is enabled, allow remote attackers to connect and issue arbitrary IPMI commands, possibly triggering a denial of service.

Multiple buffer overflows in libmcrypt before 2.5.5 allow attackers to cause a denial of service (crash).

Memory leak in libmcrypt before 2.5.5 allows attackers to cause a denial of service (memory exhaustion) via a large number of requests to the application, which causes libmcrypt to dynamically load algorithms via libtool.
