Detail
Problem Description: Updated cups packages that fix one security issue are now available for Red Hat Enterprise Linux 5 and 6. The Red Hat Security Response Team has rated this update as having moderate security impact. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available from the CVE link in the References section. 2. Relevant releases/architectures: RHEL Desktop Workstation (v. 5 client) - i386, x86_64 Red Hat Enterprise Linux (v. 5 server) - i386, ia64, ppc, s390x, x86_64 Red Hat Enterprise Linux Desktop (v. 5 client) - i386, x86_64 Red Hat Enterprise Linux Desktop (v. 6) - i386, x86_64 Red Hat Enterprise Linux Desktop Optional (v. 6) - i386, x86_64 Red Hat Enterprise Linux HPC Node (v. 6) - x86_64 Red Hat Enterprise Linux HPC Node Optional (v. 6) - x86_64 Red Hat Enterprise Linux Server (v. 6) - i386, ppc64, s390x, x86_64 Red Hat Enterprise Linux Server Optional (v. 6) - i386, ppc64, s390x, x86_64 Red Hat Enterprise Linux Workstation (v. 6) - i386, x86_64 Red Hat Enterprise Linux Workstation Optional (v. 6) - i386, x86_64 3. Description: The Common UNIX Printing System (CUPS) provides a portable printing layer for Linux, UNIX, and similar operating systems. It was discovered that CUPS administrative users (members of the SystemGroups groups) who are permitted to perform CUPS configuration changes via the CUPS web interface could manipulate the CUPS configuration to gain unintended privileges. Such users could read or write arbitrary files with the privileges of the CUPS daemon, possibly allowing them to run arbitrary code with root privileges. (CVE-2012-5519) After installing this update, the ability to change certain CUPS configuration directives remotely will be disabled by default. The newly introduced ConfigurationChangeRestriction directive can be used to enable the changing of the restricted directives remotely. Refer to Red Hat Bugzilla bug 875898 for more details and the list of restricted directives. All users of cups are advised to upgrade to these updated packages, which contain a backported patch to resolve this issue. After installing this update, the cupsd daemon will be restarted automatically. 4. Solution: Before applying this update, make sure all previously-released errata relevant to your system have been applied. This update is available via the Red Hat Network. Details on how to use the Red Hat Network to apply this update are available at https://access.redhat.com/knowledge/articles/11258 5. Bugs fixed (http://bugzilla.redhat.com/): 875898 - CVE-2012-5519 cups: privilege escalation for users of the CUPS SystemGroup group |

Title: | SUSE-SU-2013:1655-1 -- Security update for CUPS | ||
Description: | 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 <http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2012-5519 > | ||
