Descriptions

In Artifex Ghostscript through 10.01.0, there is a buffer overflow leading to potential corruption of data internal to the PostScript interpreter, in base/sbcp.c. This affects BCPEncode, BCPDecode, TBCPEncode, and TBCPDecode. If the write buffer is filled to one byte less than full, and one then tries to write an escaped character, two bytes are written.

En Artifex Ghostscript hasta la versión 10.01.0, hay un desbordamiento de búfer que puede corromper los datos internos del intérprete PostScript, en base/sbcp.c. Esto afecta a BCPEncode, BCPDecode, TBCPEncode y TBCPDecode. Si el búfer de escritura se llena hasta un byte menos de su capacidad, y se intenta escribir un carácter escapado, se escriben dos bytes.
