PEDAMACHEPHEPTOLIONES and D.B. COOPER found a stack-based buffer overflow, present in Xfig, Transfig by loading malformed .FIG files. A remote attacker could provide a specially-crafted .FIG text object file, which once opened by a local, unsuspecting user would lead to denial of service (Xfig, fig2dev crash).

Stack consumption vulnerability in ubound.c in Xfig 3.2.5b and earlier allows remote attackers to cause a denial of service (application crash) via a long string in a malformed .fig file that uses the 1.3 file format, possibly related to the readfpfig function in fread.c.
