Name of the Vulnerable Software and Affected Versions Leptonica versions prior to 1.75.4

Description The issue allows local users to potentially overwrite arbitrary files or have unspecified other impact by creating files in advance or winning a race condition, due to the use of hardcoded /tmp pathnames. This is demonstrated by the example of /tmp/junk split image.ps in prog/splitimage2pdf.c.

Recommendations For versions prior to 1.75.4, update to version 1.75.4 or later to resolve the issue. As a temporary workaround, consider restricting access to the /tmp directory to minimize the risk of exploitation.
