The remote Scientific Linux host is missing one or more security
Problem description :
A flaw was found in the way pam_console set console device
permissions. It was possible for various console devices to retain
ownership of the console user after logging out, possibly leaking
information to another local user. (CVE-2007-1716)
A flaw was found in the way the PAM library wrote account names to the
audit subsystem. An attacker could inject strings containing parts of
audit messages which could possibly mislead or confuse audit log
parsing tools. (CVE-2007-3102)
As well, these updated packages fix the following bugs :
- truncated MD5-hashed passwords in '/etc/shadow' were
treated as valid, resulting in insecure and invalid
- the pam_namespace module did not convert context names
to raw format and did not unmount polyinstantiated
directories in some cases. It also crashed when an
unknown user name was used in
'/etc/security/namespace.conf', the pam_namespace
- the pam_selinux module was not relabeling the
controlling tty correctly, and in some cases it did not
send complete information about user role and level
change to the audit subsystem.
These updated packages add the following enhancements :
- pam_limits module now supports parsing additional config
files placed into the /etc/security/limits.d/ directory.
These files are read after the main configuration file.
- the modules pam_limits, pam_access, and pam_time now
send a message to the audit subsystem when a user is
denied access based on the number of login sessions,
origin of user, and time of login.
- pam_unix module security properties were improved.
Functionality in the setuid helper binary, unix_chkpwd,
which was not required for user authentication, was
moved to a new non-setuid helper binary, unix_update.
