Hi, The following vulnerability was published for ghostscript.

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. I'm preparing an update for this issue. If you fix the vulnerability please also make sure to include the CVE (Common Vulnerabilities & Exposures) id in your changelog entry.
