Fedora Update Notification
FEDORA-2018-060302dc83
2018-12-04 02:22:12.111599
——————————————————————————–
Name : glibc
Product : Fedora 28
Version : 2.27
Release : 35.fc28
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:
This update for the `glibc` package addresses one moderate security
vulnerability and several defects. * CVE-2018-19591: A file descriptor leak in
`if_nametoindex` can lead to a denial of service due to resource exhaustion when
processing `getaddrinfo` calls with crafted host names. Reported by Guido
Vranken. (RHBZ#1654000) * Failure to create the helper thread for
`getaddrinfo_a`/`libanl` could result in a crash. (RHBZ#1646381) * On certain
Haswell-class Intel CPUs, string function feature flags could be set
incorrectly, leading to a suboptimal choice of string functions. (RHBZ#1641980)
* Parallel building of locales led to nondeterminism in the RPM build process.
(RHBZ#1652228) * Various minor bug fixes from the upstream 2.27 release branch
were imported as part of this update
