Descripción técnica

Pillow is a Python imaging library. From 2.3.0 through 12.3.0, Pillow applications that save compressed TIFF images through libtiff can pass attacker-controlled image geometry tags to the encoder while allocating its row buffer from the actual image dimensions. The affected TiffImagePlugin._save path allows ImageWidth, ImageLength, or SamplesPerPixel from exif=, tiffinfo=, or a source TIFF IFD to make libtiff consume a larger scanline than the buffer supplied by ImagingLibTiffEncode. This can read heap memory into the generated TIFF or crash the process. When TIFF Predictor 2 is enabled, libtiff can rewrite the oversized scanline in place and corrupt memory beyond the buffer. A carried-over PlanarConfiguration value of 2 instead makes libtiff use a shorter scanline and can produce an undecodable output file, but is not established to cause the out-of-bounds access. This issue is fixed in version 13.0.0.

CVE-2026-1267924.7 MED

———A memory-safety flaw in the key-management request-building component of the library can lead to an out-of-bounds write on the heap. A fixed-size output buffer is used under an assumption about cryptographic key size that is never validated, so when the library is embedded by a caller that supplies its own cryptographic callback implementation, data larger than the buffer can be written past its end. Exploitation requires the ability to control the embedding application's in-process key-management provider configuration, a high-privilege position. The demonstrated impact is memory corruption resulting in abnormal termination of the client process.1h CVE-2026-527867.1 ALT

———BACnet Stack is a BACnet open source protocol stack C library for embedded systems. Prior to versions 1.4.5, 1.5.1, and 1.6.0, in the official apps/epics client tool on v1.6.0-rc1 (not in the generic BACnet RPM ACK decoder alone) a malicious BACnet/IP endpoint can reply to the EPICS tool’s legitimate ReadPropertyMultiple request with a syntactically valid ReadPropertyMultiple-ACK that contains more heading properties than the tool’s fixed local storage can hold. The response is decoded successfully and later consumed by ProcessRPMData(), which writes property values into a fixed global array using an unbounded linear index. This results in a reproducible global-buffer-overflow in apps/epics/main.c. This is a network-reachable memory corruption in the official epics tool’s response-processing path. The root cause is that apps/epics treats a remotely supplied variable-length RPM property list as if it were a trusted, fixed-size local heading-property set. This issue has been patched in versions 1.4.5, 1.5.1, and 1.6.0.4h CVE-2026-477118.6 ALT

———BACnet Stack is a BACnet open source protocol stack C library for embedded systems. Prior to versions 1.4.4, 1.5.1, and 1.6.0, the current master demo server can be crashed remotely over BACnet/IP by sending a valid Confirmed WriteProperty request that updates loop-1's controlled-variable-reference to point to life-safety-zone-1 / accepted-modes. This issue has been patched in versions 1.4.4, 1.5.1, and 1.6.0.4h CVE-2026-477108.2 ALT

———BACnet Stack is a BACnet open source protocol stack C library for embedded systems. Prior to versions 1.4.4, 1.5.1, and 1.6.0, a stack-buffer-overflow can be triggered in the current master branch when a Loop object reads a referenced property through its default timer path and the referenced property is OBJECT_STRUCTURED_VIEW / PROP_DESCRIPTION containing a long attacker-controlled string. This issue has been patched in versions 1.4.4, 1.5.1, and 1.6.0.4h CVE-2026-472598.2 ALT

———BACnet Stack is a BACnet open source protocol stack C library for embedded systems. Prior to versions 1.4.4, 1.5.1, and 1.6.0, a RemoveListElement request targeting Notification-Class.recipient-list can trigger a stack-based out-of-bounds write in the current master branch when the request contains more than NC_MAX_RECIPIENTS valid BACnetDestination elements.
