Artifex Ghostscript < 10.01.1 Buffer Overflow

critical Nessus Plugin ID 177205

Language:

Synopsis

The remote Windows host contains a library that is affected by a buffer overflow flaw.

Description

The version of Artifex Ghostscript installed on the remote Windows host is prior to 10.01.1. It is, therefore, affected by a buffer overflow that can lead 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.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Upgrade to Artifex Ghostscript 10.01.1 or later.
