Description Andrej Nemec 2017-11-21 09:06:34 UTC

An array index error in the fig2dev program in Xfig 3.2.6a allows remote attackers to cause a denial-of-service attack with a maliciously crafted Fig format file, related to a negative font value in dev/gentikz.c, and the read_textobject functions in read.c and read1_3.c.
