Integer overflow in the js_regcomp function in regexp.c in Artifex Software, Inc. MuJS before commit b6de34ac6d8bb7dd5461c57940acfbd3ee7fd93e allows attackers to cause a denial of service (application crash) via a crafted regular expression.
The product performs a calculation that can produce an integer overflow or wraparound when the logic assumes that the resulting value will always be larger than the original value. This occurs when an integer value is incremented to a value that is too large to store in the associated representation. When this occurs, the value may become a very small or negative number.
