RHBA-2014:0470 - Bug Fix Advisory

标题

An updated nss_db package is now available for Red Hat Enterprise Linux 6.

描述

The nss_db package provides a plugin which allows libc, and in turn applications, to read information about users, groups, and other information from local database files which might otherwise need to be read from the unindexed text-like databases which are typically stored under the /etc directory on a host, or from remote servers.

This update fixes the following bug:

• Due to a programming error, the plugin provided by the nss_db package leaked the memory used to hold a copy of a database's file name whenever an application caused a database to be opened. Among the libc functions back-ended by nss_db which attempted to open databases (and thus could leak if they succeeded) were:

getaliasbyname()
getgrgid()
getgrnam()
getprotobyname()
getprotobynumber()
getpwnam()
getpwuid()
getrpcbyname()
getrpcbynumber()
getservbyname()
getservbyport()
getspnam()
getgrouplist()
setaliasent()
setetherent()
setgrent()
setnetgrent()
setprotoent()
setpwent()
setrpcent()
setservent()
setspent()

A patch has been provided to fix this bug, and debugging оr tracing no longer demonstrates the memory leak when calling the above listed functions. (BZ#1088776)

Users of nss_db are advised to upgrade to these updated packages, which fix this bug.
