An integer overflow flaw was found in pcl/pl/plfont.c:418 in pl_glyph_name in ghostscript. This issue may allow a local attacker to cause a denial of service via transforming a crafted PCL file to PDF format.
The product performs a calculation that can produce an integer overflow or wraparound when the logic assumes that the resulting value will always be larger than the original value. This occurs when an integer value is incremented to a value that is too large to store in the associated representation. When this occurs, the value may become a very small or negative number.
