Important: ecs-service-connect-agent

Issue Overview: Wasmtime is a standalone runtime for WebAssembly. Prior to versions 6.0.2, 7.0.1, and 8.0.1, Wasmtime's implementation of managing per-instance state, such as tables and memories, contains LLVM-level undefined behavior. This undefined behavior was found to cause runtime-level issu...

GHSA-JCR6-4FRQ-9GJJ Users vulnerable to unaligned read of `*const *const c_char` pointer

Affected versions dereference a potentially unaligned pointer. The pointer is commonly unaligned in practice, resulting in undefined behavior. In some build modes, this is observable as a panic followed by abort. In other build modes the UB may manifest in some other way, including the possibilit...

GHSA-F9G6-FP84-FV92 impl `FromMdbValue` for bool is unsound

The implementation of FromMdbValue has several unsoundness issues. First of all, it allows to reinterpret arbitrary bytes as a bool and could make undefined behavior happen with safe function. Secondly, it allows transmuting pointer without taking memory layout into consideration. The details of...

Null pointer dereference

A null pointer dereference issue was found in Libtiff's tifdir.c file. This issue may allow an attacker to pass a crafted TIFF image file to the tiffcp utility which triggers a runtime error that causes undefined behavior. This will result in an application crash, eventually leading to a denial o...
