Description Ganael LAPLANCHE 2007-10-13 13:50:00 UTC
Fixes several security flaws (CVE-2007-5373) that may lead to reveal the bind password and/or a user password to someone monitoring processes with `ps` while the scripts are being used. See : http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2007-5373 Changelog : 2007/10/13 : ldapscripts 1.7.1 - Fixes for CVE-2007-5373 see http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2007-5373 and http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=445582 1) Up to now, each ldap* command was called with the -w parameter, which allows to specify the bind password on the command line. Unfortunately, this could make the password appear to anybody performing a `ps` during the call. This is now avoided by using the -y parameter and a password file. -> A new BINDPWDFILE option has been added : it specifies the path to the bind password file. This file can be created by something like : 'echo -n 'password' > $BINDPWDFILE' and you can now safely remove (or comment) the BINDPWD parameter from your configuration file. 2) Changing a user password could also reveal the new password on the command line, because of the use of ldappasswd's -s option. This has been fixed by using a temporary file containing the new password (and ldappassword's -T option). -> [internals] New mktempf() and reltempf() functions have been added [For older versions of OpenLDAP, -y and -T parameters may not be available. It is still possible to use the old BINDPWD parameter. Just uncomment it from the configuration file and comment the BINDPWDFILE parameter (which takes precedence over BINDPWD). The ldapscripts will just behave as previously and use inline -w and -s parameters, warning you this is not secure way of running them.] 3) A similar problem related to sed expressions has been found : it may also lead to reveal a user's password to `ps` users. This is now fixed by using temporary files containing sed expressions (and sed's -f option). 4) A new test has been added to check if 'echo' and '[' are built-in or not. If not, you'll be warned that the ldapscripts may not be safe to use (because these commands manipulate passwords when creating temporary files). -> [internals] New is_builtin() function Note that these flaws depend largely on your kernel configuration : hardened kernels should not be impacted (e.g. if you use security.bsd.see_other_[u|g]ids sysctls on FreeBSD). It may also depend on the version of OpenLDAP client commands you run. Thanks a lot to Don and Madcoder for their help ! - Few fixes to avoid using non-standard 'if ! command's...
