Amazon Linux 2023 Security Advisory: ALAS-2023-162
Advisory Release Date: 2023-04-27 20:00 Pacific
Advisory Updated Date: 2023-05-03 13:25 Pacific
Severity:
Important
Issue Overview:
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. (CVE-2023-28879)
