  script_tag(name:"insight", value:"Updated glibc packages fixes the following security issue:

On the x86-64 architecture, the GNU C Library (aka glibc) before 2.31
fails to ignore the LD_PREFER_MAP_32BIT_EXEC environment variable
during program execution after a security transition, allowing local
attackers to restrict the possible mapping addresses for loaded
libraries and thus bypass ASLR for a setuid program (CVE-2019-19126).

Other upstream fixes in this update:
- Call _dl_open_check after relocation [BZ #24259]
- support: Export bindir path on support_path
- nss_db: fix endent wrt NULL mappings [BZ #24695] [BZ #24696]
- elf: Refuse to dlopen PIE objects [BZ #24323]
- Fix alignment of TLS variables for tls variant TLS_TCB_AT_TP [BZ #23403]
- Fix assertion in malloc.c:tcache_get
- Small tcache improvements
- malloc: Remove unwanted leading whitespace in malloc_info [BZ #24867]
- malloc: Fix missing accounting of top chunk in malloc_info [BZ #24026]
- Add glibc.malloc.mxfast tunable
- malloc: Various cleanups for malloc/tst-mxfast
- Base max_fast on alignment, not width, of bins [BZ #24903]
- Linux: Use in-tree copy of SO_ constants for !__USE_MISC [BZ #24532]");
