Descrição técnica

When psqlODBC quotes a schema or table name into a 128-byte stack buffer, its length check lets it write up to two bytes past the end of the buffer for a long name. The names come from the application's SQL text: the table of a statement the driver parses to describe its columns, and the target of the last INSERT when the driver rewrites SELECT @@IDENTITY. In the @@IDENTITY rewrite, a column name sent by the server can also write one byte past the buffer. The bytes written past the buffer are a double quote and a NUL. An application that forwards untrusted SQL text to the driver exposes its process to stack corruption. Versions before psqlODBC 18.00.0006 are affected.

———imgproxy 3.3.0 before 4.0.17 contains an out-of-bounds heap read and write in the ICO loader's BMP header reconstruction (vips_foreign_load_ico_header in vips/icoload.c) when an ICO entry declares a tiny data size, causing unvalidated header fields to be read and written past the allocated buffer. Unauthenticated remote attackers can supply a crafted ICO image to corrupt adjacent heap chunk metadata, triggering a glibc abort that crashes the worker.5h CVE-2026-174017.2 ALT

——18IBM API Connect 10.0.8.0 through 10.0.8.12 and 12.1.0.0 through 12.1.1.2 could allow a remote authenticated attacker to execute arbitrary code due to a stack-based buffer overflow.1d CVE-2026-104267—

——0Botan 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 3.13.0.1d CVE-2026-777085.9 MÉD

——1EDFbrowser 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.2d CVE-2026-1123355.5 MÉD

——1Wazuh agent from 1.0.0 before 4.14.9 contains a stack-based buffer overflow in the logcollector snort-full log reader that miscalculates remaining buffer space in read_snortfull(). Attackers who write crafted multi-line content to a monitored snort-full log can overflow the 65,280-byte stack buffer, crashing the agent or overwriting an SEH handler on 32-bit Windows agents running as SYSTEM.1d
