Loop with Unreachable Exit Condition ('Infinite Loop')
The ReadCAPTIONImage function in "coders/caption.c" in ImageMagick6 before 6.9.9-15 and ImageMagick7 before 7.0.7-4 allows remote attackers to cause a denial of service (infinite loop) via a crafted font file.
CWE-835 - Loop with Unreachable Exit Condition
Loops with multiple exits and flags detract from the quality of an application. They tend to make control structures difficult to understand, and introduce the risk of non-termination and other structural problems. The vulnerability “loop with unreachable exit condition” enables attackers to exploit this flaw, leading to denial of service.
