CWE-122 11/07/2026
ImageMagick - Heap Buffer Overflow Read via Unrecognized Magnify Method
ImageMagick before 7.1.2-19 contains a heap buffer overflow vulnerability in the magnify operation that allows attackers to read out of bounds memory. An unrecognized magnify:method value triggers an out of bounds read, potentially exposing sensitive information or causing denial of service.
CVE-2026-57156
Crítica · 9.8
CWE-122 10/07/2026
FreeRDP: Integer overflow leading to heap buffer overflow in Orders Delta Points parsing
FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to 3.28.0 on 32-bit builds, FreeRDP clients contain an integer overflow in update_read_delta_points in libfreerdp/core/orders.c when multiplying an attacker-controlled point count by sizeof(DELTA_POINT), allowing a malicious RDP peer to allocate an undersized heap buffer and then write beyond it during initialization. This issue is fixed in version 3.28.0.
CVE-2026-54001

CWE-122 10/07/2026
osquery: Heap buffer overflow via `authenticode` table (Windows)
osquery is a SQL powered operating system instrumentation, monitoring, and analytics framework. Prior to 5.23.1, on Windows, a local unprivileged attacker can cause a heap buffer out-of-bounds write if there is a query of the authenticode table targeting a maliciously crafted binary, due to publisher information parsing in getOriginalProgramName. If exploited successfully, this could allow a potential local privilege escalation from standard user to SYSTEM. This issue is fixed in version 5.23.1.
CVE-2026-54000
Alta · 7.0
CWE-122 10/07/2026
osquery: Heap buffer overflow in `getProcessCurrentDirectory()` via `processes` table (Windows)
osquery is a SQL powered operating system instrumentation, monitoring, and analytics framework. Prior to 5.23.1, on Windows, a local unprivileged attacker can cause a heap buffer out-of-bounds write if there is a query of the processes table targeting a maliciously crafted process, due to unchecked PEB string lengths in process command-line and current-directory reads. If exploited successfully, this could allow a potential local privilege escalation from standard user to SYSTEM. This issue is fixed in version 5.23.1.
