Description

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.
