Hi,
The following vulnerability was published for ghostscript.
CVE-2023-28879[0]:
| 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.
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.
