Fedora 23: 2015-7174c4d68d Moderate: Glibc Function Security Update

This update re-adds large file support to the `openat` function, removes support for the `LD_POINTER_GUARD` environment variable (which could be used to weaken security protections in `AT_SECURE`/SUID binaries), and adds function pointer obfuscation to the TLS destructor list.. -------------------------------------------------------------------------------- Fedora Update Notification FEDORA-2015-7174c4d68d 2015-12-06 17:43:07.764319 -------------------------------------------------------------------------------- Name : glibc Product : Fedora 23 Version : 2.22 Release : 6.fc23 URL : 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 re-adds large file support to the `openat` function, removes support for the `LD_POINTER_GUARD` environment variable (which could be used to weaken security protections in `AT_SECURE`/SUID binaries), and adds function pointer obfuscation to the TLS destructor list. -------------------------------------------------------------------------------- References: [ 1 ] Bug #1276761 - glibc: apply additional pointer guard hardening https://bugzilla.redhat.com/show_bug.cgi?id=1276761 [ 2 ] Bug #1288662 - openat() && write() broken on i386 with _FILE_OFFSET_BITS 64 https://bugzilla.redhat.com/show_bug.cgi?id=1288662 -------------------------------------------------------------------------------- This update can be installed with the "yum" update program.
