rust-openssl has undefined behavior in X509Ref::ocsp_responders for certificates with non-UTF-8 OCSP URLs

X509Ref::ocspresponders returns OCSP responder URLs from a certificate's AIA extension as OpensslString, whose Deref wraps the raw bytes with str::fromutf8unchecked. OpenSSL does not enforce that the underlying IA5String is ASCII, so a certificate with non-UTF-8 bytes in its OCSP accessLocation...

Name of the Vulnerable Software and Affected Versions rust-openssl versions 0.9.7 through 0.10.78 Description The X509Ref::ocsp responders function returns OCSP responder URLs from a certificate's AIA extension as OpensslString. The Deref implementation wraps raw bytes using str::from utf8...

Null-pointer dereference and double-free via safe APIs

Two soundness violations exist in the Rust bindings for MetaCall: Null-pointer dereference: MetaCallFuture::newraw accepts a raw pointer without validation. The Debug impl calls Box::fromrawself.data on it. Passing a null pointer causes the Debug impl to construct a NonNull from null, producing...

RUSTSEC-2026-0133 Invalid pointer arithmetic in `iter()` and `iter_mut()`

The iter and itermut APIs compute current = &children0 as const const RawAutoChild.sub1, which performs pointer subtraction going before the start of the allocation. This is undefined behavior per Rust's pointer arithmetic rules. This can be triggered through safe public APIs — iter and itermut —...

RUSTSEC-2026-0123 Out-of-bounds read in `bytes_helper` public safe functions

The byteshelper module contains multiple public functions intoarr4, intoarr2, u8fromlebytes that use slice.getuncheckedpos..pos + N without verifying that pos + N = slice.len. These are public safe API functions, allowing any caller to trigger undefined behavior by passing invalid positions. For...

Grid: Integer Overflow in Grid::expand_rows Leads to Safe-API Undefined Behavior

Summary An integer overflow in Grid::expandrows can corrupt the relationship between the grid’s logical dimensions and its backing storage. After the internal invariant is broken, the safe API get may invoke getunchecked with an invalid index, resulting in Undefined Behavior. Details Tested...
