Oj: Use-After-Free in Oj::Parser array_class/hash_class GC Marking

Summary Oj::Parser in usual mode does not mark arrayclass and hashclass references during garbage collection. If GC runs after the class is assigned but before a parse, the class object is reclaimed, leaving the parser holding a dangling VALUE. The subsequent parse call dereferences the freed...

OSEC-2026-04 Bigarray.reshape integer overflow

The function camlbareshape, part of the OCaml runtime in runtime/bigarray.c, had a missing check for integer overflow when computing the size to be allocated. This leads to a segmentation fault. Any application using Bigarray.reshape or reshapeN with untrusted and unchecked input can result in a...

postgresql: integer overflow can cause an undersized allocation and an out-of-bounds write

A flaw was found in PostgreSQL. An integer overflow in multiple server features allows an unprivileged database user to cause an undersized memory allocation that leads to an out-of-bounds write. This issue allows an attacker to execute arbitrary code as the operating system user running the...
