NVD Description

Note: Versions mentioned in the description apply only to the upstream libgs-devel package and not the libgs-devel package as distributed by RHEL. See How to fix? for RHEL:8 relevant fixed versions and status.

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.
