CVE-2024-29507

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.
