[Bug 665209] Re: Ctrl-\ after rejected key-encryption password causes hang

[Maarten Bezemer]

I was too hasty: while I was typing my response,  openssl repeatedly
displaying the password prompt without responding to user input as you
described.

Title:
  Ctrl-\ after rejected key-encryption password causes hang

Status in “openssl” package in Ubuntu:
  Confirmed

Bug description:
  Binary package hint: openssl

  Create the following shell script:

  #!/bin/sh
  openssl genrsa -aes256

  And run it.

  After a key is generated, you will be prompted for an encryption
  password.  Press enter.  Since empty passwords are not allowed here,
  you will be prompted a second time.  Now press Ctrl-\.  Openssl then
  falls into an infinite loop of repeatedly displaying the password
  prompt without responding to user input.

  This behavior does *not* seem to occur if:

  1. You run openssl directly from the shell rather than from a shell script; or
  2. You press Ctrl-\ immediately without first having a password rejected; or
  3. You use an openssl built from upstream sources.  Hence, this seems to be a Debian- or Ubuntu-specific bug.
