Artifex MuJS v1.1.3 was discovered to contain a heap buffer overflow which is caused by conflicting JumpList of nested try/finally statements.

In MuJS before version 1.1.2, a use-after-free flaw in the regexp source property access may cause denial of service.

Artifex MuJS through 1.0.7 has a use-after-free in jsrun.c because of unconditional marking in jsgc.c.

Buffer overflow vulnerability in function jsG_markobject in jsgc.c in mujs before 1.0.8, allows remote attackers to cause a denial of service.

Buffer overflow vulnerability in mujs before 1.0.8 due to recursion in the GC scanning phase, allows remote attackers to cause a denial of service.

An issue was discovered in Artifex MuJS 1.0.5. regcompx in regexp.c does not restrict regular expression program size, leading to an overflow of the parsed syntax list size.

An issue was discovered in Artifex MuJS 1.0.5. It has unlimited recursion because the match function in regexp.c lacks a depth check.

An issue was discovered in Artifex MuJS 1.0.5. jscompile.c can cause a denial of service (invalid stack-frame jump) because it lacks an ENDTRY opcode call.

An issue was discovered in Artifex MuJS 1.0.5. The Number#toFixed() and numtostr implementations in jsnumber.c have a stack-based buffer overflow.

The js_strtod function in jsdtoa.c in Artifex MuJS through 1.0.2 has an integer overflow because of incorrect exponent validation.

jsparse.c in Artifex MuJS through 1.0.2 does not properly maintain the AST depth for binary expressions, which allows remote attackers to cause a denial of service (excessive recursion) via a crafted file.
