Descripción técnica

Memory safety bugs present in Firefox ESR 115.32, Firefox ESR 140.7, Thunderbird ESR 140.7, Firefox 147 and Thunderbird 147. Some of these bugs showed evidence of memory corruption and we presume that with enough effort some of these could have been exploited to run arbitrary code. This vulnerability was fixed in Firefox 148, Firefox ESR 115.33, Firefox ESR 140.8, Thunderbird 148, and Thunderbird 140.8.

CVE-2026-892668.2 ALT

—

———stb_vorbis through 1.22 contains a heap buffer overflow in start_decoder() where the codebook multiplicands allocation size is truncated from size_t to int. Attackers can craft a malicious Ogg Vorbis file with large entries and dimensions values to trigger out-of-bounds writes, causing process crashes or heap corruption.11h CVE-2026-542407.4 ALT

———libde265 is an open source implementation of the h.265 video codec. Versions prior to 1.1.1 use signed 32-bit arithmetic to calculate pixel offsets, allowing a crafted HEVC stream with large image dimensions to trigger an integer overflow and cause out-of-bounds heap reads or writes, potentially disclosing data, corrupting memory, or crashing the decoder. Version 1.1.1 contains a patch.14h CVE-2026-47773—

———ArduinoBLE enables Bluetooth Low Energy connectivity on certain Arduino models. Versions prior to 2.0.2 contain a missing bounds check in the ATT layer write request handler that allows a remote, unauthenticated BLE client to corrupt memory in the ATTClass global object. Devices running ArduinoBLE with one or more characteristics configured with the BLEEncryption property are affected. The fix is included starting from the 2.0.2 release.14h CVE-2026-78547—

———Out-of-bounds write vulnerability in Citrix Citrix Workspace app for Windows. This issue affects Citrix Workspace app for Windows: before 2603.11 Current Release (CR), before 2507.1 LTSR CU3, and before LTSR 2607.15h CVE-2026-457707.5 ALT

——0Suricata is a network Intrusion Detection System, Intrusion Prevention System and Network Security Monitoring engine. Starting in version 8.0.0 and prior to version 8.0.5, a Lua rule that registers too many flow variables can corrupt Lua detection state and may bypass Suricata's restricted Lua sandbox. This requires an affected Lua script/rule to be loaded. Excessive flow variables being registered may also cause Suricata to crash. Version 8.0.5 contains a fix. As a workaround, disable `security.lua.allow-rules` unless Lua rules are required.17h CVE-2026-88053—

——0Tesseract is an open source OCR engine. In version 5.5.3 and earlier, Classify::ReadIntTemplates in src/classify/intproto.cpp reads NumClassPruners, NumClasses, and NumProtoSets from the TESSDATA_INTTEMP component of a crafted .traineddata file and uses those values as loop bounds without validating them against MAX_NUM_CLASS_PRUNERS, MAX_NUM_CLASSES, and MAX_NUM_PROTO_SETS. The loops store heap pointers into fixed-capacity ClassPruners and ProtoSets arrays in INT_TEMPLATES_STRUCT and INT_CLASS_STRUCT, so an oversized count causes heap out-of-bounds pointer writes during legacy-classifier initialization before OCR begins, resulting in heap corruption, a crash, or potentially controlled corruption. No fixed release is available as of this review.19h
