Package : openssh Version : 1:5.5p1-6+squeeze7 CVE ID : CVE-2015-5600 In Debian LTS (squeeze), the fix for CVE-2015-5600[1] in openssh 1:5.5p1-6+squeeze7 breaks authentication mechanisms that rely on the keyboard-interactive method. Thanks to Colin Watson for making aware of that. The patch fixing CVE-2015-5600 introduces the field 'devices_done' to the KbdintAuthctxt struct, but does not initialize the field in the kbdint_alloc() function. On Linux, this ends up filling that field with junk data. The result of this are random login failures when keyboard-interactive authentication is used. This upload of openssh 1:5.5p1-6+squeeze7 to Debian LTS (squeeze) adds that initialization of the `devices_done` field alongside the existing initialization code. People relying on keyboard-interactive based authentication mechanisms with OpenSSH on Debian squeeze(-lts) systems are recommended to upgrade OpenSSH to 1:5.5p1-6+squeeze7.
