Descripción técnica

Pillow is a Python imaging library. From 1.0 through 12.3.0, ImageFileDirectory_v2.load() in src/PIL/TiffImagePlugin.py retains a separate bytes object for each out-of-line IFD tag value without limiting the total data read or preventing distinct tags from referencing the same file region. A small crafted TIFF or EXIF-bearing JPEG, PNG, WebP, or MPO can therefore cause memory use quadratic in the input size. TIFF and some JPEG paths trigger parsing during Image.open(), while other formats are exposed when EXIF is requested, including through getexif() or ImageOps.exif_transpose(). The declared pixel dimensions do not bound this metadata allocation, so decompression-bomb checks do not prevent process memory exhaustion. This issue is fixed in version 13.0.0.

———MessagePack for Ruby is an implementation of the MessagePack binary serialization format. Prior to 1.8.7, the Java-platform msgpack gem for JRuby allocated arrays and byte buffers directly from attacker-controlled array32, str32, and bin32 declared sizes before confirming that corresponding elements or bytes were available. A short MessagePack header could therefore trigger a very large allocation or sustained heap growth when an application decoded untrusted input through MessagePack.unpack or MessagePack::Unpacker, potentially exhausting the shared JVM heap. map32 and declared counts at or above 2^31 did not use the affected allocation behavior. This issue is fixed in version 1.8.7.4h CVE-2026-818436.5 MED

———Grafana is an open-source platform for monitoring and observability. When an Elasticsearch data source is configured with a time-based index pattern, Grafana generated one index name for every interval in the requested query time range without any upper limit. A user with permission to query the data source, which includes users holding only the Viewer role in a default configuration, could submit a single small query with an extreme time range and cause the server to allocate memory until it was terminated. The allocation occurred before any request was sent to Elasticsearch, so the condition applied whether or not the Elasticsearch cluster was reachable. Data sources configured with a static index name are not affected.9h CVE-2026-685397.5 ALT

——0fulgur converts untrusted HTML/CSS into PDF, commonly on a server that processes input supplied by many tenants. From version 0.4.4 to before version 0.29.0, the CSS string-set named-string values resolved from a document were accumulated per element with no memory budget, letting a small crafted document amplify into large retained memory (and the CPU to copy it) — results in a denial of service. This issue has been patched in version 0.29.0.10h CVE-2026-1262447.5 ALT

——0A flaw was found in Cockpit. This vulnerability allows a remote attacker, without prior authentication, to send specially crafted fragmented WebSocket messages. These messages accumulate without a total-size limit, leading to unbounded memory exhaustion and a denial of service in the `cockpit-ws` service.11h
