+Subject: [PATCH] patch 9.2.0075: [security]: Buffer underflow with emacs tag
+ file
+
+Problem:  When parsing a malformed Emacs-style tags file, a 1-byte
+          heap-buffer-underflow read occurs if the 0x7f delimiter
+          appears at the very beginning of a line. This happens
+          because the code attempts to scan backward for a tag
+          name from the delimiter without checking if space exists.
+          (ehdgks0627, un3xploitable)
+Solution: Add a check to ensure the delimiter (p_7f) is not at the
+          start of the buffer (lbuf) before attempting to isolate
+          the tag name.
