RedHat: RHSA-2021-0348:01 Moderate: glibc security and bug fix update
Summary
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)
Summary
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.
