The release/2.29/master branch has been updated by Patricia Franklin
<patsy@sourceware.org>:
https://sourceware.org/git/gitweb.cgi?p=glibc.git;h=0474cd5de60448f31d7b872805257092faa626e4
commit 0474cd5de60448f31d7b872805257092faa626e4
Author: Joseph Myers <joseph@codesourcery.com>
Date: Wed Feb 12 23:31:56 2020 +0000
Avoid ldbl-96 stack corruption from range reduction of pseudo-zero (bug
25487).
Bug 25487 reports stack corruption in ldbl-96 sinl on a pseudo-zero
argument (an representation where all the significand bits, including
the explicit high bit, are zero, but the exponent is not zero, which
is not a valid representation for the long double type).
Although this is not a valid long double representation, existing
practice in this area (see bug 4586, originally marked invalid but
subsequently fixed) is that we still seek to avoid invalid memory
accesses as a result, in case of programs that treat arbitrary binary
data as long double representations, although the invalid
representations of the ldbl-96 format do not need to be consistently
handled the same as any particular valid representation.
This patch makes the range reduction detect pseudo-zero and unnormal
representations that would otherwise go to __kernel_rem_pio2, and
returns a NaN for them instead of continuing with the range reduction
process. (Pseudo-zero and unnormal representations whose unbiased
exponent is less than -1 have already been safely returned from the
function before this point without going through the rest of range
reduction.) Pseudo-zero representations would previously result in
the value passed to __kernel_rem_pio2 being all-zero, which is
definitely unsafe; unnormal representations would previously result in
a value passed whose high bit is zero, which might well be unsafe
since that is not a form of input expected by __kernel_rem_pio2.
Tested for x86_64.
(cherry picked from commit 9333498794cde1d5cca518badf79533a24114b6f)

This was fixed in 2020 with the work to handle pseudo-zero. Changing from
RESOLVED INVALID to RESOLVED FIXED.
