Descripción técnica

Tesseract is an open source OCR engine. Prior to 5.5.4, GENERIC_2D_ARRAY::DeSerializeSize in src/ccstruct/matrix.h reads matrix dimensions as signed int32_t values and compares them only with UINT16_MAX, allowing negative values to reach ResizeNoInit. Negative dimensions or a 65535 by 65535 product can create inconsistent allocation state and later out-of-bounds accesses while loading a crafted traineddata file, causing denial of service. This issue is fixed in version 5.5.4.

———go-xrpl is a Go implementation of the XRP Ledger protocol. In versions through the June 18, 2026 revision identified by the advisory, `ParseMPTAmountBinary` in `internal/ledger/state/ripple_state.go` converts the eight-byte MPT magnitude using `num.Int64()` without checking that it fits in 63 bits. A positive magnitude of at least 2^63 silently wraps into a negative amount without an error. `ParseEscrow` passes 33-byte `sfAmount` fields to the parser and stores `MPTRaw()` in `EscrowData.MPTAmount`, causing incorrect downstream calculations and divergence from rippled's interpretation of the same escrow entry. Independently, `readMPTAmount` in `internal/tx/ledgerfields/decode_stream.go` accepts over-limit magnitudes and surfaces large decimal strings without enforcing the maximum signed 64-bit value. The public codec in codec/binarycodec/types/amount.go already rejects these values, leaving the internal decoders inconsistent with that safe path. A source fix is available in commit 9dbd3935ed6c54f0232f2291edf9c012a0900dd5.5h CVE-2026-1197296.5 MED

———A flaw was found in GStreamer. An integer overflow vulnerability in the AV1 LEB128 variable-length integer parser allows a remote attacker to cause a crash in applications that process AV1 media content. By crafting a malformed AV1 bitstream containing an invalid LEB128-encoded value, an attacker can cause integer overflow in the parser, resulting in incorrect length values being used during stream processing, which can lead to a denial of service.5h CVE-2026-1197197.8 ALT

———Blender before 4.5.15 and 5.x before 5.2.3 contains a heap buffer overflow vulnerability in the blend file thumbnail extractor caused by 32-bit integer overflow in thumb_data_vertical_flip(). Attackers can craft a .blend file with malicious TEST block dimensions that trigger an out-of-bounds write when blender-thumbnailer or the Windows shell extension previews it, causing crashes or code execution.6h CVE-2026-1197187.8 ALT

———Blender before 4.5.15 and 5.x before 5.2.3 contains a heap buffer overflow vulnerability caused by integer overflow in ptcache_data_alloc() when reading point cache files. Attackers can supply a crafted point cache file with a large totpoint value alongside a .blend file to crash Blender or execute code as the user.6h CVE-2026-1040647.8 ALT

———Scribus before 1.6.7 contains an integer overflow vulnerability in the scimgdataloader_tiff TIFF loader that allows attackers to trigger a heap overflow via crafted tile dimensions. Attackers can supply a tiled TIFF with large tile width, height and sample values for a user to import, corrupting heap memory to crash Scribus or execute code.6h CVE-2026-116366—
