Multiple soundness issues in `macroquad`

Several soundness issues have been reported. Resolving them doesn't seem to be considered a priority. In particular, unprincipled use of mutable statics is pervasive throughout the library, making it possible to cause use-after-free in safe code. Currently, no fixed version is available...

`VMABuffer::set_data` may allow out-of-bounds writes from safe code

VMABuffer::setdata was a publicly accessible safe function. It accepted an arbitrary offset and a data slice, then used the offset in unsafe pointer arithmetic before copying the slice into a mapped allocation. Affected versions did not check that the requested write range fit within the allocati...

Use-After-Free in `Md::fetch` and `Cipher::fetch`

When a Some... value was passed to the properties argument of either of these functions, a use-after-free would result. In practice this would nearly always result in OpenSSL treating the properties as an empty string due to CString::drop's behavior. The maintainers thank quitbug for reporting th...

gix-worktree-state nonexclusive checkout sets executable files world-writable

Summary gix-worktree-state specifies 0777 permissions when checking out executable files, intending that the umask will restrict them appropriately. But one of the strategies it uses to set permissions is not subject to the umask. This causes files in a repository to be world-writable in some...

Segmentation fault due to lack of bound check

In this case, the "fastfloat::common::AsciiStr::first" method within the "AsciiStr" struct uses the unsafe keyword to reading from memory without performing bounds checking. Specifically, it directly dereferences a pointer offset by "self.ptr". Because of the above reason, the method accesses...

Malicious plugin names, recipients, or identities can cause arbitrary binary execution

A plugin name containing a path separator may allow an attacker to execute an arbitrary binary. Such a plugin name can be provided to the rage CLI through an attacker-controlled recipient or identity string, or an attacker-controlled plugin name via the -j flag. On UNIX systems, a directory...
