Descrição técnica

Pillow is a Python imaging library. Prior to 13.0.0, Pillow's FlashPix JPEG-tile decoder can write decoded scanlines beyond the allocated tile buffer. FlashPix (FPX) JPEG decoding selects raw mode LA with two bytes per pixel, while an unrecognized JPEG mode can be decoded as JCS_UNKNOWN with four components, causing ImagingJpegDecode to write four-component scanlines into the two-byte tile buffer. An attacker can supply a crafted OLE2 FlashPix file to an application with the optional olefile dependency installed that opens or thumbnails untrusted input. This can corrupt heap memory and may allow arbitrary code execution. This issue is fixed in version 13.0.0.

———A vulnerability was determined in Tenda AC19 16.03.10.07. Affected by this issue is the function saveParentControlInfo of the file /goform/saveParentControlInfo. This manipulation of the argument deviceId causes heap-based buffer overflow. The attack is possible to be carried out remotely. The exploit has been publicly disclosed and may be utilized.6h CVE-2026-104267—

———Botan is a C++ cryptography library. From 2.7.0 until 3.13.0, Botan's Scrypt implementation on 32-bit platforms computes required memory with unchecked multiplication, allowing attacker-controlled Scrypt parameters to wrap the allocation size and create a buffer smaller than the algorithm subsequently writes. The issue affects systems that enable Scrypt and accept arbitrary parameters from a hostile source, including applications that decrypt attacker-supplied encrypted private keys. A triggering parameter set can cause approximately four gigabytes of Scrypt output to be written past the allocated heap buffer, immediately crashing the process and causing denial of service. Arbitrary code execution is not demonstrated and appears difficult, but cannot be excluded from the overwrite primitive. This issue is fixed in version 3.13.0.22h CVE-2026-823087.5 ALT

——0A heap-based buffer overflow in the TDS prelogin parser in the Babelfish for PostgreSQL extension versions 1.0-1.5, 2.1-2.15, 3.1-3.12, 4.0-4.8, 5.1-5.4 and in Amazon Aurora PostgreSQL with Babelfish might allow remote attackers to execute arbitrary OS commands as the database process user via a specially crafted malformed TDS prelogin packet to the TDS port. This record consolidates a related NULL-pointer-dereference finding in the same prelogin parser. To remediate this issue, we recommend users upgrade to Babelfish for PostgreSQL extension versions 4.10, 5.6, 6.1 or later. As a workaround, restrict network access to the TDS port (default 1433). Customers using Amazon Aurora PostgreSQL with Babelfish should upgrade their cluster to Aurora PostgreSQL 13.9.16 (1.5.5), 13.23.3 (1.17.2), 14.6.16 (2.3.5), 14.17.8 (2.12.4), 14.18.6 (2.13.3), 14.19.5 (2.14.2), 14.20.5 (2.15.2), 14.22.3 (2.16.1), 14.23.1 (2.17.0), 15.10.8 (3.8.4), 15.12.8 (3.9.4), 15.13.6 (3.10.3), 15.14.5 (3.11.2), 15.15.5 (3.12.2), 15.17.3 (3.13.1), 15.18.1 (3.14.0), 16.8.8 (4.5.5), 16.9.6 (4.6.3), 16.10.5 (4.7.2), 16.11.5 (4.8.2), 16.13.3 (4.9.1), 16.14.1 (4.10.0), 17.4.8 (5.1.4), 17.5.6 (5.2.3), 17.6.5 (5.3.2), 17.7.5 (5.4.2), 17.9.3 (5.5.1), 17.10.1 (5.6.0), 18.3.4 (6.0.2), 18.4.1 (6.1.0) or later, and apply any pending maintenance to ensure they are on the latest patch.23h CVE-2026-1239765.5 MÉD

——0EDFbrowser before 2.16 contains an out-of-bounds write vulnerability in check_edf_file() that allows attackers to overflow the 256-element annot_ch array by supplying excessive annotation signals. Attackers can craft an EDF+ or BDF+ file with more than 256 annotation signals to overwrite edfhdrblock members, including the signal parameter pointer, crashing the application when opened.1d
