Dell BIOS contains a race condition vulnerability. A local attacker could exploit this vulnerability by sending malicious input via SMI in order to bypass security checks during SMM.
Dell BIOS versions contain a stack-based buffer overflow vulnerability. A local attacker could exploit this vulnerability by sending malicious input via SMI to bypass security checks resulting in arbitrary code execution in SMM.
Dell BIOS versions contain an Insecure Automated Optimization vulnerability. A local authenticated malicious user could exploit this vulnerability by sending malicious input via SMI to obtain arbitrary code execution during SMM.
Dell Client Consumer and Commercial Platforms contain an Arbitrary File Overwrite Vulnerability. The vulnerability is limited to the Dell Firmware Update Utility during the time window while being executed by an administrator. During this time window, a locally authenticated low-privileged malicious user could exploit this vulnerability by tricking an administrator into overwriting arbitrary files via a symlink attack. The vulnerability does not affect the actual binary payload that the update utility delivers.
