QID 670992: EulerOS Security Update for glibc (EulerOS-SA-2021-2631)

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. Security Fix(es): A flaw was found in the GNU C library (glibc), where the sysdeps/unix/sysv/linux/mq_notify.c function mishandles certain NOTIFY_REMOVED data, leading to a NULL pointer dereference. The highest threat from this vulnerability is to system availability.(CVE-2021-38604)
