  "details": "NLnet Labs Unbound up to and including version 1.25.0 has a vulnerability in the DNSSEC validator where the code path to consult the negative cache for DS records does not take into account the limit on NSEC3 hash calculations introduced in 1.19.1. This leads to degradation of service during the attack. An adversary that controls a DNSSEC signed zone can exploit this by signing NSEC3 records with acceptably high iterations for child delegations and querying a vulnerable Unbound. Unbound will keep performing the allowed hash calculations on the NSEC3 records and will not limit the work by the mitigation introduced in 1.19.1. As a side effect, a global lock for the negative cache will be held for the duration of the hashing, blocking other threads that need to consult the negative cache. Coordinated attacks could raise the vulnerability to denial of service. Unbound 1.25.1 contains a patch with a fix to bound the vulnerable code path with the existing limit for NSEC3 hash calculations.",

A small crafted payload (tens of kilobytes) containing an OID with many arcs consumes seconds of CPU per decode() call, allowing denial of service in any application that decodes untrusted ASN.1 data (certificates, LDAP, SNMP, Kerberos, etc.). The corresponding encoders have the same quadratic behavior, reachable when an application re-encodes previously decoded attacker-supplied values.\n\nThe arc-size limit introduced for CVE-2026-23490 bounds the byte length of an individual arc but not the number of arcs, so it does not mitigate this issue.\n\n### Affected components\nObjectIdentifierPayloadDecoder and RelativeOIDPayloadDecoder in pyasn1/codec/ber/decoder.py; ObjectIdentifierEncoder and RelativeOIDEncoder in pyasn1/codec/ber/encoder.py. The CER and DER codecs inherit these and are equally affected.\n\n### Patches\nFixed in pyasn1 0.6.4: arc accumulation in both decoders and encoders now runs in linear time.\n\n### Workarounds\nLimit the size of untrusted ASN.1 input before decoding.",

  "details": "### Impact\n\n`AttributesExtension` ships with the library but must be explicitly registered on the `Environment`; it is not included in `CommonMarkConverter`, `GithubFlavoredMarkdownConverter`, or `GithubFlavoredMarkdownExtension`. **Applications that do not register `AttributesExtension` are not affected by this advisory.**\n\nTwo paths in the extension re-process every attribute a node has already collected each time another attribute is applied to it. When the attributes carry distinct names, the collected set grows by one on every step and is walked again in full, so a run of *n* attributes costs O(n\u00b2).\n\n**1. Attribute nodes resolving to a common target (affected from 1.5.0).**\n\n`AttributesListener::processDocument()` merges each attribute node into the set accumulated for its target, then filters the result. Both operations traverse that entire set: `AttributesHelper::mergeAttributes()` rebuilds it with `array_merge()`, and `AttributesHelper::filterAttributes()` matches a regular expression against every name in it. A run of attribute nodes sharing one target therefore re-walks a set that grows by a key per node.\n\nTwo input shapes reach this path: adjacent inline attributes at the start of a block (`{a0=\"v\"}{a1=\"v\"}\u2026`, where quoting the values is what keeps them separate \u2014 an unquoted value swallows the `}{` that follows it), and a chain of attribute blocks held at their default target by reference definitions (`{a0=v}` / `[a]: u` / `{a1=v}` / `[a]: u` / \u2026).\n\n256 KB of adjacent inline attributes takes 20.0 seconds to convert, against 0.09 seconds once patched.\n\n**2. Consecutive attribute-block lines (affected from 2.0.0).**\n\n`AttributesBlockContinueParser::tryContinue()` merges each continuation line into the block\u0027s accumulated attributes, again rebuilding the whole set on every line. One distinct attribute per line (`{a0=v}` / `{a1=v}` / \u2026) grows it by a key each time.\n\n256 KB of such lines takes 1.9 seconds to convert while producing **zero bytes of output**, against 0.08 seconds once patched.\n\n**Relationship to GHSA-jjv6-8j6v-6j52.** The fix released in 2.9.1 for that advisory made the `class` attribute cheap to accumulate, but left every other attribute name on the original path. **Applications that upgraded to 2.9.1 or 2.9.2 remain exposed to this variant.**\n\n**Overall impact.** An unauthenticated attacker who can submit Markdown to an affected application can consume disproportionate CPU time with a comparatively small request, occupying PHP workers and preventing legitimate requests from completing. The impact is limited to availability: no data is disclosed, rendered output is unchanged, and no rendering restriction is bypassed.\n\n### Patches\n\nThe issue is patched in `2.10.0`. Both paths now fold each node \u2014 or each line \u2014 into the accumulated attributes at a cost proportional to that node or line alone, rather than re-merging and re-filtering everything gathered so far. Rendered output is unchanged, down to the order in which attributes appear.\n\nThe listener path affects `1.5.0` through `2.9.2`. The continuation-line path affects `2.0.0` through `2.9.2`. The 1.x release line is no longer supported, so its users must upgrade to `2.10.0` or later.\n\n### Workarounds\n\nIf you cannot upgrade immediately:\n\n- **Do not register `AttributesExtension`** when converting untrusted Markdown. This fully removes both paths.\n- If the extension is required, **impose a strict maximum input length before conversion**. Because the cost is quadratic, the cap must be small to meaningfully bound worst-case CPU time.\n\nThe `attributes/allow` allow-list added in 2.7.0 is **not** a mitigation. A non-empty allow-list happens to bound the first path, because unlisted names are discarded before they accumulate, but it does nothing for the second: continuation lines are merged while parsing, before any filtering takes place.\n\nRestricting conversion to trusted users, applying strict execution-time limits, and rate-limiting requests reduce exposure but are not substitutes for upgrading.",

The _is_consonant() helper walks backward over the entire run of trailing \u0027y\u0027 characters on every call, and _measure() invokes it for each stem position, causing O(n^2) behavior. A single ~20-50 KB untrusted token consisting of a long run of the letter \u0027y\u0027 followed by a matching suffix (e.g., \u0027ness\u0027) can pin a CPU core for seconds to minutes, causing availability impact.",
