The product performs operations on a memory buffer, but it can read from or write to a memory location that is outside of the intended boundary of the buffer. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

An issue was discovered in OpenVMS through V8.4-2L2 on Alpha and through V8.4-2L1 on IA64, and VAX/VMS 4.0 and later. A malformed DCL command table may result in a buffer overflow allowing a local privilege escalation when a non-privileged account enters a crafted command line. This bug is exploitable on VAX and Alpha and may cause a process crash on IA64. Software was affected regardless of whether it was directly shipped by VMS Software, Inc. (VSI), HPE, HP, Compaq, or Digital Equipment Corporation.

The bug was discovered 02/06/2018. The weakness was presented 02/07/2018 (Website). The advisory is shared at openvms.org.
