Stack-based buffer overflow in the read13textobject function in freadold.c in Xfig 3.2.5b and earlier, and in the readtextobject function in read13.c in fig2dev in Transfig 3.2.5a and earlier, allows remote attackers to execute arbitrary code via a long string in a malformed .fig file that uses the 1.3 file format.
