+-printf: incorrect output for integers with thousands separator and width field
+-
+-When the printf family of functions is called with a format specifier
+-that uses an <apostrophe> (enable grouping) and a minimum width
+-specifier, the resulting output could be larger than reasonably expected
+-by a caller that computed a tight bound on the buffer size.  The

+-GNU C Library Security Advisory Format
+-======================================
+-
+-Security advisories in this directory follow a simple git commit log
+-format, with a heading and free-format description augmented with tags
+-to allow parsing key information.  References to code changes are
+-specific to the glibc repository and follow a specific format:
+-
+-  Tag-name: <commit-ref> (release-version)
+-
+-The <commit-ref> indicates a specific commit in the repository.  The
+-release-version indicates the publicly consumable release in which this
+-commit is known to exist.  The release-version is derived from the
+-git-describe format, (i.e. stripped out from glibc-2.34.NNN-gxxxx) and
+-is of the form 2.34-NNN.  If the -NNN suffix is absent, it means that
+-the change is in that release tarball, otherwise the change is on the
+-release/2.YY/master branch and not in any released tarball.
+-
+-The following tags are currently being used:
+-
+-CVE-Id:
+-This is the CVE-Id assigned under the CVE Program
+-(https://www.cve.org/).
+-
+-Public-Date:
+-The date this issue became publicly known.
+-
+-Vulnerable-Commit:
+-The commit that introduced this vulnerability.  There could be multiple
+-entries, one for each release branch in the glibc repository; the
+-release-version portion of this tag should tell you which branch this is
+-on.
+-
+-Fix-Commit:
+-The commit that fixed this vulnerability.  There could be multiple
+-entries for each release branch in the glibc repository, indicating that
+-all of those commits contributed to fixing that issue in each of those
+-branches.
+-
+-Adding an Advisory
+-------------------
+-
+-An advisory for a CVE needs to be added on the master branch in two steps:
+-
+-1. Add the text of the advisory without any Fix-Commit tags along with
+-   the fix for the CVE.  Add the Vulnerable-Commit tag, if applicable.
+-   The advisories directory does not exist in release branches, so keep
+-   the advisory text commit distinct from the code changes, to ease
+-   backports.  Ask for the GLIBC-SA advisory number from the security
+-   team.
+-
+-2. Finish all backports on release branches and then back on the msater
+-   branch, add all commit refs to the advisory using the Fix-Commit
+-   tags.  Don't bother adding the release-version subscript since the
+-   next step will overwrite it.
+-
+-3. Run the process-advisories.sh script in the scripts directory on the
+-   advisory:
+-
+-     scripts/process-advisories.sh update GLIBC-SA-YYYY-NNNN
+-
+-   (replace YYYY-NNNN with the actual advisory number).
+-
+-4. Verify the updated advisory and push the result.
+-
+-Getting a NEWS snippet from advisories
+---------------------------------------
+-
+-Run:
+-
+-  scripts/process-advisories.sh news
+-
+-and copy the content into the NEWS file.
