glibc: security bump to the latest 2.26 branch
List of fixes from the 2.26 branch NEWS files:
CVE-2017-15670: The glob function, when invoked with GLOB_TILDE,
suffered from a one-byte overflow during ~ operator processing (either
on the stack or the heap, depending on the length of the user name).
Reported by Tim Rühsen.
CVE-2017-15671: The glob function, when invoked with GLOB_TILDE,
would sometimes fail to free memory allocated during ~ operator
processing, leading to a memory leak and, potentially, to a denial
of service.
CVE-2017-15804: The glob function, when invoked with GLOB_TILDE and
without GLOB_NOESCAPE, could write past the end of a buffer while
unescaping user names. Reported by Tim Rühsen.
CVE-2017-17426: The malloc function, when called with an object size near
the value SIZE_MAX, would return a pointer to a buffer which is too small,
instead of NULL. This was a regression introduced with the new malloc
thread cache in glibc 2.26. Reported by Iain Buclaw.
