+Subject: [PATCH] Use vasprintf() if available for error messages and otherwise
+ vsnprintf()
+
+vasprintf() is a GNU/BSD extension and would allocate as much memory as required
+on the heap, similar to g_strdup_printf(). It's ridiculous that such a function
+is still not provided as part of standard C.
+
+If it's not available, use vsnprintf() to at least avoid stack/heap buffer
+overflows, which can lead to arbitrary code execution.
+
+Thanks to Noriko Totsuka for reporting.
+
+Fixes JVN#02030803 / JPCERT#92912620 / CVE-2024-40897
+Fixes #69
+
