Dell UEFI BIOS https stack leveraged by the Dell BIOSConnect feature and Dell HTTPS Boot feature contains an improper certificate validation vulnerability. A remote unauthenticated attacker may exploit this vulnerability using a person-in-the-middle attack which may lead to a denial of service and payload tampering.

Dell BIOSConnect feature contains a buffer overflow vulnerability. An authenticated malicious admin user with local access to the system may potentially exploit this vulnerability to run arbitrary code and bypass UEFI restrictions.

Dell BIOSConnect feature contains a buffer overflow vulnerability. An authenticated malicious admin user with local access to the system may potentially exploit this vulnerability to run arbitrary code and bypass UEFI restrictions.

Dell BIOS contains a heap buffer overflow vulnerability. A local attacker with admin privileges could potentially exploit this vulnerability to perform an arbitrary write to SMRAM during SMM.

Dell BIOS contains a Stack based buffer overflow vulnerability. A local authenticated attacker could potentially exploit this vulnerability by using an SMI to send larger than expected input to a parameter to gain arbitrary code execution in SMRAM.
