Hi, Thanks for submitting this report. I've removed the security label from the bug after reading through the comments and the referenced bug. Modifying argv is not terribly portable and I think a reasonable person would expect that a password specified on the command line would be visible through a ps.
Patches would certainly be considered but I don't consider this a security issue. Just a request for an enhancement. ** Information type changed from Private Security to Private ** Information type changed from Private to Public -- You received this bug notification because you are a member of qemu- devel-ml, which is subscribed to QEMU. https://bugs.launchpad.net/bugs/1136477 Title: qemu doesn't sanitize command line options carrying plaintext passwords Status in QEMU: New Bug description: A slight security problem exists with qemu's lack of sanitization of argv[], for cases where the user may have specified a plaintext password for spice/vnc authorization. (Yes, it's not great to use this facility, but it's convenient and not grotesquely unsafe, were it not for this bug.) It would be nice if those plaintext passwords were nuked from the command line, so a subsequent "ps awux" didn't show them for all to see.
