Xfig v3.2.8 was discovered to contain a NULL pointer dereference when calling XGetWMHints(). NOTE: this is disputed because it is not expected that an X application should continue to run when there is arbitrary anomalous behavior from the X server or window manager.

xfig 3.2.7 is vulnerable to Buffer Overflow.

An array index error in the fig2dev program in Xfig 3.2.6a allows remote attackers to cause a denial-of-service attack or information disclosure with a maliciously crafted Fig format file, related to a negative font value in dev/gentikz.c, and the readtextobject functions in read.c and read13.c.

readcolordef in read.c in Xfig fig2dev 3.2.7b has an out-of-bounds write.

readtextobject in read.c in Xfig fig2dev 3.2.7b has a stack-based buffer overflow because of an incorrect sscanf.

Xfig fig2dev 3.2.7a has a stack-based buffer overflow in the calcarrow function in bound.c.

fig2dev 3.2.7b contains a segmentation fault in the readobjects function in read.c.

fig2dev 3.2.7b contains a segmentation fault in the gencgmstart function in gencgm.c.

fig2dev 3.2.7b contains a stack buffer overflow in the readtextobject function in read.c.

fig2dev 3.2.7b contains a global buffer overflow in the getline function in read.c.

fig2dev 3.2.7b contains a stack buffer overflow in the bezierspline function in genepic.c.

fig2dev 3.2.7b contains a global buffer overflow in the convpatternindex function in gencgm.c.

fig2dev 3.2.7b contains a global buffer overflow in the setfigfont function in genepic.c.

An issue was discovered in fig2dev before 3.2.8.. A NULL pointer dereference exists in the function computeclosedspline() located in transspline.c. It allows an attacker to cause Denial of Service. The fixed version of fig2dev is 3.2.8.
