Similar to CVE-2017-8782,Integer overflow in function readString,src/actioncompiler/listaction.c:103

[b0b0haha]

Hi ,I use static analysis tool to find a vulnerable func similar to readString(util/read.c)
Just similar to commit befb74,in func readString (src/actioncompiler/listaction.c) ,there should be a check to avoid buflen integer overflow before line 103. What's more ,there should be a check for buf which is initialized in line 95 in case of malloc fails.
