Security update for CUPS
SUSE Security Update: Security update for CUPS
The following security issue has been fixed in the CUPS
print daemon CVE-2012-5519:
The patch adds better default protection against misuse of
privileges by normal users who have been specifically
allowed by root to do cupsd configuration changes
The new ConfigurationChangeRestriction cupsd.conf directive
specifies the level of restriction for cupsd.conf changes
that happen via HTTP/IPP requests to the running cupsd
(e.g. via CUPS web interface or via the cupsctl command).
By default certain cupsd.conf directives that deal with
filenames, paths, and users can no longer be changed via
requests to the running cupsd but only by manual editing
the cupsd.conf file and its default file permissions
permit only root to write the cupsd.conf file.
Those directives are: ConfigurationChangeRestriction,
AccessLog, BrowseLDAPCACertFile, CacheDir, ConfigFilePerm,
DataDir, DocumentRoot, ErrorLog, FileDevice, FontPath,
Group, LogFilePerm, PageLog, Printcap, PrintcapFormat,
PrintcapGUI, RemoteRoot, RequestRoot, ServerBin,
ServerCertificate, ServerKey, ServerRoot, StateDir,
SystemGroup, SystemGroupAuthKey, TempDir, User.
The default group of users who are allowed to do cupsd
configuration changes via requests to the running cupsd
(i.e. the SystemGroup directive in cupsd.conf) is set to
'root' only.
Additionally the following bug has been fixed:
* strip trailing "@REALM" from username for Kerberos
authentication (CUPS STR#3972 bnc#827109)
Security Issue reference:
* CVE-2012-5519
