Vulnerabilidades

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 segmentation fault in the gencgm_start function in gencgm.c.

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

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

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

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

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

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.

Stack-based buffer overflow in Xfig 3.2.4 and 3.2.5 allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via a FIG image with a crafted color definition.

Stack consumption vulnerability in u_bound.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 readfp_fig function in f_read.c.

Stack-based buffer overflow in the read_1_3_textobject function in f_readold.c in Xfig 3.2.5b and earlier, and in the read_textobject function in read1_3.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…

Xfig, possibly 3.2.5, allows local users to read and write arbitrary files via a symlink attack on the (1) xfig-eps[PID], (2) xfig-pic[PID].pix, (3) xfig-pic[PID].err, (4) xfig-pcx[PID].pix, (5) xfig-xfigrc[PID], (6) xfig[PID], (7) xfig-print[PID], (8) xfig-export[PID].err, (9) xfig-batch[PID], (10) xfig-exp[PID], or…
