FEDORA-2025-69207650a4
2025-01-27 01:55:15.215467+00:00
--------------------------------------------------------------------------------
Name : glibc
Product : Fedora 40
Version : 2.39
Release : 37.fc40
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 addresses two security vulnerabilities:
* CVE-2025-0395: A buffer overflow may occur in the assert function with certain
large program names and assert expressions.
* CVE-2025-0577: getrandom, arc4random can produce predictable randomness if a
multi-threaded program creates additional threads after fork.
The following non-security bugs are fixed:
* Compatibility with certain programs that call free(environ) is improved
(however, deallocating environ remains undefined in general).
* Crashes in string functions on certain hypervisors that report L3 cache sizes
above 4 GiB are avoided.
* Poor performance of x86-64 string functions in certain cases.
* Initialization of the restartable sequence area now follows recommended
practices.
--------------------------------------------------------------------------------
ChangeLog:
* Fri Jan 24 2025 Florian Weimer [fweimer@redhat.com] - 2.39-37
- setenv: Rework free(environ) compatibility support (RHEL-75809)
* Thu Jan 23 2025 Florian Weimer [fweimer@redhat.com] - 2.39-36
- CVE-2025-0577: vDSO getrandom predictable randomness after fork (RHEL-75555)
* Thu Jan 23 2025 Florian Weimer [fweimer@redhat.com] - 2.39-35
- Restore compatibility with environ/malloc usage pattern (RHEL-75809)
* Thu Jan 23 2025 Florian Weimer [fweimer@redhat.com] - 2.39-34
- Sync with upstream branch release/2.39/master,
commit 808a84a8b81468b517a4d721fdc62069cb8c211f:
- Fix underallocation of abort_msg_s struct (CVE-2025-0395)
- x86/string: Fixup alignment of main loop in str{n}cmp-evex [BZ #32212]
- x86: Improve large memset perf with non-temporal stores [RHEL-29312]
- x86: Avoid integer truncation with large cache sizes (bug 32470)
- math: Exclude internal math symbols for tests [BZ #32414]
- malloc: add indirection for malloc(-like) functions in tests [BZ #32366]
- Pass -nostdlib -nostartfiles together with -r [BZ #31753]
- nptl: initialize cpu_id_start prior to rseq registration
- nptl: initialize rseq area prior to registration

Summary : The Identity, Policy and Audit system
Description :
IPA is an integrated solution to provide centrally managed Identity (users,
hosts, services), Authentication (SSO, 2FA), and Authorization
(host access control, SELinux user roles, services). The solution provides
features for further integration with Linux based clients (SUDO, automount)
and integration with Active Directory based infrastructures (Trusts).
