RHBA-2005:678 - Bug Fix Advisory

Topic

Updated glibc packages that address several bugs are now available.

Description

The GNU libc packages (known as glibc) contain the standard C libraries
used by applications.

This erratum addresses the following bugs in the GNU C Library:

• make sure nscd cmsg buffers are not misaligned, handle EINTR

from poll when contacting nscd more gracefully

• remove malloc attribute from posix_memalign
• correctly size nscd buffer for grpcache key
• fix atan2f function
• avoid memory leaks in error function
• several execvp fixes
• include program name in __chk_fail error message
• do not write 0 to gid/uid column for group or username starting

with + or - in putgrent or putpwent

• fix Yen mapping ib IBM930 and IBM939 charsets
• add sr_CS{,.UTF-8} locales, update mn_MN, pa_IN and fa_IR locales
• make sure EINVAL is returned from pthread_create if requested

thread scheduling priority is invalid

• change NPTL <pthread.h> initializers to avoid warnings, with

both -pedantic and -W GCC options

• fix NPTL <pthread.h> with -ansi -fexceptions
• avoid SIGPIPE in nscd
• fix nscd -g yes/no strings
• fix *scanf if decimal point is more than one byte long
• fix rpcgen to output #include <rpc/pmap_clnt.h> even without -C
• handle 'z' in strptime*
• properly propagate return values in nss_compat
• avoid some unnecessary PLT relocations
• remove nonnull attribute from acct function
• allow NLS of some strings that could not be translated before
• update IA-64 libm from Intel 2005-04-05
• fix initgroups when passed zero-size buffer
• add 19 UTF-8 locales where only non-UTF-8 locales existed before
• add several sunrpc xdr fixes for 64-bit architectures
• fix posix_fallocate and posix_fallocate64
• use -laudit in nscd
• handle big amounts of networking interfaces in getifaddrs

and if_nameindex

• fix nscd cache pruning
• try more ports in bindresvport if all 600..1023 are used, do not use

priviledged ports when talking to portmap

• support classes keyword in /etc/hesiod.conf
• fix IBM939 iconv module
• fix malloc_trim function
• change sys/quota.h to match current kernel's quotactl interface, include

support for the obsoleted interface (no longer supported in current
kernels) with -D_LINUX_QUOTA_VERSION=1

• make regexec thread safe
• make -lrpcsvc and -lmcheck usable for PIEs and shared libraries
• fix sendfile and sendfile64 prototypes
• do not use nisplus in nsswitch.conf examples, mention that nisplus

is unsupported

• do not use symbolic register names %rdi and %rbx in x86-64 cfi

directives to workaround GNU assembler bug

• fix strfry, initstate and initstate_r functions
• fix nis memory handling when realloc fails
• work around an ia32el problem when running glibc_post_upgrade in

i?86.rpm glibc on ia64 under ia32el

All users of glibc should upgrade to these updated packages, which resolve
these issues.

Solution

Before applying this update, make sure that all previously-released
errata relevant to your system have been applied. Use Red Hat
Network to download and update your packages. To launch the Red Hat
Update Agent, use the following command:
