-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 ==================================================================== Red Hat Security Advisory Synopsis: Moderate: glibc security and bug fix update Advisory ID: RHSA-2021:0348-01 Product: Red Hat Enterprise Linux Advisory URL: https://access.redhat.com/errata/RHSA-2021:0348 Issue date: 2021-02-02 CVE Names: CVE-2019-25013 CVE-2020-10029 CVE-2020-29573 ==================================================================== 1. Summary: An update for glibc is now available for Red Hat Enterprise Linux 7. Red Hat Product Security has rated this update as having a security impact of Moderate. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section. 2. Relevant releases/architectures: Red Hat Enterprise Linux Client (v. 7) - x86_64 Red Hat Enterprise Linux Client Optional (v. 7) - x86_64 Red Hat Enterprise Linux ComputeNode (v. 7) - x86_64 Red Hat Enterprise Linux ComputeNode Optional (v. 7) - x86_64 Red Hat Enterprise Linux Server (v. 7) - ppc64, ppc64le, s390x, x86_64 Red Hat Enterprise Linux Server Optional (v. 7) - ppc64, ppc64le, s390x, x86_64 Red Hat Enterprise Linux Workstation (v. 7) - x86_64 Red Hat Enterprise Linux Workstation Optional (v. 7) - x86_64 3. Description: The glibc packages provide the standard C libraries (libc), POSIX thread libraries (libpthread), standard math libraries (libm), and the name service cache daemon (nscd) used by multiple programs on the system. Without these libraries, the Linux system cannot function correctly. Security Fix(es): * glibc: buffer over-read in iconv when processing invalid multi-byte input sequences in the EUC-KR encoding (CVE-2019-25013) * glibc: stack corruption from crafted input in cosl, sinl, sincosl, and tanl functions (CVE-2020-10029) * glibc: stack-based buffer overflow if the input to any of the printf family of functions is an 80-bit long double with a non-canonical bit pattern (CVE-2020-29573) For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section. Bug Fix(es): * glibc: 64bit_strstr_via_64bit_strstr_sse2_unaligned detection fails with large device and inode numbers (BZ#1883162) * glibc: Performance regression in ebizzy benchmark (BZ#1889977) 4. Solution: For details on how to apply this update, which includes the changes described in this advisory, refer to: https://access.redhat.com/articles/11258 For the update to take effect, all services linked to the glibc library must be restarted, or the system rebooted. 5. Bugs fixed (https://bugzilla.redhat.com/): 1810670 - CVE-2020-10029 glibc: stack corruption from crafted input in cosl, sinl, sincosl, and tanl functions 1905213 - CVE-2020-29573 glibc: stack-based buffer overflow if the input to any of the printf family of functions is an 80-bit long double with a non-canonical bit pattern 1912960 - CVE-2019-25013 glibc: buffer over-read in iconv when processing invalid multi-byte input sequences in the EUC-KR encoding 6.
