+Subject: [PATCH] Bug 707510 - don't use strlen on passwords
+
+Item #1 of the report. This looks like an oversight when first coding
+the routine. We should use the PostScript string length, because
+PostScript strings may not be NULL terminated (and as here may contain
+internal NULL characters).
+
+Fix the R6 handler which has the same problem too.
+
+CVE: CVE-2024-29509
