Originalnachricht

Name        : glibc
Product : Fedora 19
Version : 2.17
Release : 13.fc19
URL : http://www.gnu.org/software/glibc/
Summary : The GNU libc libraries
Description :
The glibc package contains standard libraries which are used by
multiple programs on the system. In order to save disk space and
memory, as well as to make upgrading easier, common system code is
kept in one place and shared between programs. This particular package
contains the most important sets of shared libraries: the standard C
library and the standard math library. Without these two libraries, a
Linux system will not function.

Update Information:

glibc security update:

CVE-2012-4412 glibc: strcoll() integer overflow leading to buffer overflow
CVE-2012-4424 glibc: alloca() stack overflow in the strcoll() interface
CVE-2013-1914 glibc: Stack (frame) overflow in getaddrinfo() when processing
entry mapping to long list of address structures
CVE-2013-2207 glibc (pt_chown): Improper pseudotty ownership and permissions
changes when granting access to the slave pseudoterminal
CVE-2013-4237 glibc: Buffer overwrite when using readdir_r on file systems
returning file names longer than NAME_MAX characters

Fix for CVE-2013-2207 may break chroots if their devpts was not mounted
correctly. Fix is to mount the devpts correctly with gid=5.
