DLA-3381-1 ghostscript -- LTS security update
- Date Reported:
- 04 Apr 2023
- Affected Packages:
- Security database references:
- In Mitre's CVE dictionary: CVE-2023-28879.
- More information:
It was discovered that there was a potential buffer-overflow vulnerability in ghostscript, a popular interpreter for the PostScript language used, for example, to generate PDF files.
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.
For Debian 10
Buster, this problem has been fixed in version 9.27~dfsg-2+deb10u7.
We recommend that you upgrade your ghostscript packages.
