+	  <p>The problematic function in question is putSDN() in mail.c. The static variable `cp` is used as an index for a fixed-sized buffer `ibuf`. There is a range check: `if ( cp >= HDR_BUF_LEN ) ...` but under certain circumstances, cp can be incremented beyond the buffer size, leading to a buffer overwrite</p>
