+Subject: [PATCH] Fix CVE-2023-43788: Out of bounds read in
+ XpmCreateXpmImageFromBuffer
+
+When the test case for CVE-2022-46285 was run with the Address Sanitizer
+enabled, it found an out-of-bounds read in ParseComment() when reading
+from a memory buffer instead of a file, as it continued to look for the
+closing comment marker past the end of the buffer.
