d3f928944("BUG/MINOR: cli: Issue an error when too many args are passed for a command") added a new check to prevent the command to run when too many arguments are provided. In this case an error is reported. However it turns out this check (despite marked for backports) was ineffective prior to20ec1de21("MAJOR: cli: Refacor parsing and execution of pipelined commands") as 'p' pointer was reset to the end of the buffer before the check was executed. Now since20ec1de21, the check works, but we have another issue: we may read past initialized bytes in the buffer because 'p' pointer is always incremented in a while loop without checking if we increment it past 'end' (This was detected using valgrind) To fix the issue introduced by20ec1de21, let's only increment 'p' pointer if p < end. For 3.2 this is it, now for older versions, sinced3f928944was marked for backport, a sligthly different approach is needed: - conditional p increment must be done in the loop (as in this patch) - max arg check must moved above "fill unused slots" comment where p is assigned to the end of the buffer This patch should be backported withd3f928944.
