Dell Digital Delivery, versions prior to 5.2.0.0, contain a Buffer Overflow Vulnerability. A local low privileged attacker could potentially exploit this vulnerability, leading to arbitrary code execution and/or privilege escalation.
A heap overflow condition is a buffer overflow, where the buffer that can be overwritten is allocated in the heap portion of memory, generally meaning that the buffer was allocated using a routine such as malloc().
The product copies an input buffer to an output buffer without verifying that the size of the input buffer is less than the size of the output buffer, leading to a buffer overflow.
