Vulnerabilities

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

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

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

read_textobject 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 calc_arrow function in bound.c.

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 read_textobject functions in read.c and read1_3.c.
