    2.7.2
        Security fixes:
		CVE-2025-59375 -- Disallow use of disproportional amounts of
                    dynamic memory from within an Expat parser (e.g. previously
                    a ~250 KiB sized document was able to cause allocation of
                    ~800 MiB from the heap, i.e. an "amplification" of factor
                    ~3,300); once a threshold (that defaults to 64 MiB) is
                    reached, a maximum amplification factor (that defaults to
                    100.0) is enforced, and violating documents are rejected
                    with an out-of-memory error.
                    There are two new API functions to fine-tune this new
                    behavior:
                      - XML_SetAllocTrackerActivationThreshold
                      - XML_SetAllocTrackerMaximumAmplification .
                    If you ever need to increase these defaults for non-attack
                    XML payload, please file a bug report with libexpat.
                      There is also a new environment variable
                    EXPAT_MALLOC_DEBUG=(0|1|2) to control the verbosity
                    of allocations debugging at runtime, disabled by default.
                      Known impact is (reliable and easy) denial of service:
                    CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H/E:H/RL:O/RC:C
                    (Base Score: 7.5, Temporal Score: 7.2)
                    Please note that a layer of compression around XML can
                    significantly reduce the minimum attack payload size.
                      Distributors intending to backport (or cherry-pick) the
                    fix need to copy 99% of the related pull request, not just
                    the "lib: Implement tracking of dynamic memory allocations"
                    commit, to not end up with a state that literally does both
                    too much and too little at the same time. Appending ".diff"
                    to the pull request URL could be of help.
