Description

Artifex Ghostscript before 10.03.0 sometimes has a stack-based buffer overflow via the CIDFSubstPath and CIDFSubstFont parameters.
A flaw was found in Ghostscript. Under specific conditions, the `cidfsubstpath` and `cidfsubstfont` parameters set by corresponding Postscript objects are used to load substitute fonts in `pdfi_open_CIDFont_substitute_file`. The values are copied via `memcpy` into the `fontfname` buffer without bounds checks. This flaw allows an attacker to pass values larger than the buffer size to trigger a stack buffer overflow, leading to a denial of service or other unexpected behavior.
