Detailed vulnerability description
The vulnerability allows a remote attacker to cause DoS condition on the target system.
The weakness exists due to use-after-free in RenderFreetype in MagickCore/annotate.c. A remote attacker can provide a specially crafted font file, call the FT_Done_Glyph function (from FreeType 2) at an incorrect place in the ImageMagick code, trigger memory corruption and cause the application to crash.
Successful exploitation of the vulnerability results in denial of service.
