Common Weakness Enumeration (CWE)

Common Attack Pattern Enumeration and Classification (CAPEC)

  • Overread Buffers
    An adversary attacks a target by providing input that causes an application to read beyond the boundary of a defined buffer. This typically occurs when a value influencing where to start or stop reading is set to reflect positions outside of the valid memory location of the buffer. This type of attack may result in exposure of sensitive information, a system crash, or arbitrary code execution.

descriptionThe version of Symantec Endpoint Protection Manager (SEPM) installed on the remote host is 14.x prior to 14.2 RU2 MP1. It is, therefore, affected by multiple out-of-bounds read vulnerabilities. An unauthenticated, remote attacker can exploit this to read memory outside of the bounds of the memory that had been allocated to the program.
