   An update that solves three vulnerabilities and has two
   fixes is now available.

Description:

   This update for glibc fixes the following issues:

   - CVE-2020-1752: Fixed a use after free in glob which could have allowed a
     local attacker to create a specially crafted path that, when processed
     by the glob function, could potentially have led to arbitrary code
     execution (bsc#1167631).
   - CVE-2020-1751: Fixed an array overflow in backtrace for PowerPC
     (bsc#1158996).
   - CVE-2020-10029: Fixed a stack buffer overflow during range reduction
     (bsc#1165784).
   - Use 'posix_spawn' on popen preventing crash caused by 'subprocess'.
     (bsc#1149332, BZ #22834)
   - Fix handling of needles crossing a page, preventing incorrect results to
     return during the cross page boundary search. (bsc#1157893, BZ #25226)
