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

Description An issue was discovered where the gplotMakeOutput function does not block '/' characters in the gplot rootname argument, potentially leading to path traversal and arbitrary file overwrite.

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 the use of the gplotMakeOutput function to minimize the risk of exploitation.
