Description:
Some vulnerabilities have been reported in the GD Graphics Library, which can potentially be exploited to cause a DoS (Denial of Service).
1) An integer overflow exists in the "gdImageCreateTrueColor()" function.
2) An error in the "gdImageCreateXbm()" function can potentially be exploited to cause a crash.
3) An error in the processing of GIF images with no global color map can potentially be exploited to cause a crash.
4) An error in gd_gif_in.c can be exploited to cause a heap corruption via an image file with an invalid color index in the image data.
5) An error in the imagearc and imagefilledarc functions can be exploited to consume large amounts of CPU resources via overly large start and end angle values.
6) A race-condition error in "gdImageStringFTEx()" in gdft.c can potentially be exploited to cause a crash.
Various issues in the GIF reader have also been reported as security related.
