5.301. setup 5.301.1. RHBA-2012:1367 - setup bug fix update Updated setup packages that fix three bugs are now available for Red Hat Enterprise Linux 6. The setup packages provide a set of important system configuration and setup files, such as passwd, group, and profile. Bug Fixes BZ# 791140 Prior to this update, the "/etc/profile" script used a non-portable method for undefining the pathmunge() function. As a consequence, the script could encounter problems when using the korn shell (ksh). This update modifies the undefining method of the function to work more efficiently with alternative shells. BZ# 839410 , BZ# 860221 Prior to this update, the accounts for the haproxy system user, the jbosson-agentsystem user, and the jbosson system group were created with dynamic uid/gid assignment, which is not recommended for network daemons and for sensitive data. With this update, the static uid/gid pair 188:188 can be used to create these users and groups. All users of setup are advised to upgrade to these updated packages, which fix these bugs. 5.301.2. RHBA-2012:0778 - setup bug fix and enhancement update An updated setup package that fixes three bugs and adds various enhancements is now available for Red Hat Enterprise Linux 6. The setup package contains a set of important system configuration and setup files, such as passwd, group, and profile. Bug Fixes BZ# 771388 Prior to this update, the /etc/filesystems configuration file did not contain a line with the ext4 file system. This could lead to various problems; for example, a process that used the file to determine supported file systems was not able to recognize ext4 as a valid file system. This update adds the missing line in the /etc/filesystems file. BZ# 710185 Prior to this update, the /etc/services configuration file contained an entry with the Internet Assigned Numbers Authority (IANA) reservation of port 0 for the spr-itunes service. However, the reservation of port 0 does not represent a real port reservation (it is only acknowledgment of IANA that the service exists). The spr-itunes entry has been commented out in the /etc/services file and an extended comment has been added to clarify the issue. BZ# 724007 Prior to this update, the /etc/group configuration file contained unnecessary supplementary groups - especially the root groups posed some potential security risk. These groups were legacy remnants and are no longer required. To mitigate the risk of making some future exploit more severe only because of the root's supplementary groups, the groups have been removed from the defaults. Enhancements BZ# 772746 The wallaby package creates a user ID (UID) and a group ID (GID) pair, both with the name "wallaby" and number 181. Prior to this update, the UID and GID pairs were not reserved by the setup package. As a consequence, other packages or system administrators could accidentally assign the values to other users and groups. With this update, the setup package reserves these UID/GID names and numbers, so that accidental UID/GID usage risk is reduced. BZ# 760178 The tog-pegasus-libs package creates a user ID (UID) and a group ID (GID) pair, both with the name "cimsrvr" and number 134. Prior to this update, the UID and GID pairs were not reserved by the setup package. As a consequence, other packages or system administrators could accidentally assign the values to other users and groups. With this update, the setup package reserves these UID/GID names and numbers, so that accidental UID/GID usage risk is reduced. BZ# 738294 The sanlock package creates a user ID (UID) and a group ID (GID) pair, both with the name "sanlock" and number 179. Prior to this update, the UID and GID pairs were not reserved by the setup package. As a consequence, other packages or system administrators could accidentally assign the values to other users and groups. With this update, the setup package reserves these UID/GID names and numbers, so that accidental UID/GID usage risk is reduced. BZ# 738177 The dhcp package creates a user ID (UID) and a group ID (GID) pair, both with the name "dhcpd" and number 177. Prior to this update, the UID and GID pairs were not reserved by the setup packages. As a consequence, other packages or system administrators could accidentally assign the values to other users and groups. With this update, the setup package reserves these UID/GID names and numbers, so that accidental UID/GID usage risk is reduced. BZ# 804203 , BZ# 804204 , BZ# 804205 , BZ# 806052 A new cloud engine feature requires new users and groups - namely aeolus, katello, elasticsearch and mongodb with numbers 180, 182, 183 and 184. Prior to this update, the UID and GID pairs were not reserved by the setup packages. To prevent accidental UID/GID usage by other packages or system administrators, the aforementioned UID/GID names and number are now reserved by the setup package. All users of setup are advised to upgrade to this updated package, which fixes these bugs and add these enhancements.
