<blockquote>
<h2>Release 0.6.4</h2>
<p>This is a security release.</p>
<ul>
<li>CVE-2026-59885 (GHSA-8ppf-4f7h-5ppj): Fixed quadratic time
complexity in the OBJECT IDENTIFIER and RELATIVE-OID decoders. A small
crafted substrate encoding many arcs could consume excessive CPU.</li>
<li>CVE-2026-59884 (GHSA-m4p7-r5rc-7g4j): Limited BER long-form tag IDs
to 20 octets (140 bits). Unbounded tag IDs allowed a crafted substrate
to consume excessive CPU and memory.</li>
<li>CVE-2026-59886 (GHSA-hm4w-wwcw-mr6r): Fixed excessive memory and CPU
consumption in <code>Real.__float__()</code> for values with large
base-10 exponents.</li>
<li>Pinned PyPI publish GitHub Action to an immutable commit.</li>

<h2>Revision 0.6.4, released 08-07-2026</h2>
<ul>
<li>CVE-2026-59885 (GHSA-8ppf-4f7h-5ppj): Fixed quadratic time
complexity in the OBJECT IDENTIFIER and RELATIVE-OID decoders.
A small crafted substrate encoding many arcs could consume
excessive CPU. Arcs are now accumulated in linear time; decoded
values are unchanged (thanks for reporting, tynus2)</li>
<li>CVE-2026-59884 (GHSA-m4p7-r5rc-7g4j): Limited BER long-form tag
IDs to 20 octets (140 bits), matching the OID arc limit introduced
in 0.6.2. Unbounded tag IDs allowed a crafted substrate to consume
excessive CPU and memory; longer tag IDs are now rejected with
PyAsn1Error. Also fixed Tag and TagSet repr() failing on huge tag
(thanks for reporting, mikeappsec)
IDs due to the integer-to-string conversion limit (Python 3.11+)</li>
<li>CVE-2026-59886 (GHSA-hm4w-wwcw-mr6r): Fixed excessive memory and
CPU consumption in Real.<strong>float</strong>() for values with large
base-10
exponents. Conversion no longer materializes huge intermediate
integers; values too large to represent as a Python float raise
OverflowError promptly, and prettyPrint() renders them as
'<!-- raw HTML omitted -->' as before. Also fixed base-10 mantissa
normalization
to use exact integer arithmetic; mantissas larger than 2**53
could previously lose precision through float division
(thanks for reporting, gvozdila)</li>
<li>Pinned PyPI publish GitHub Action to an immutable commit
