- CWE-755
Description
In the standard library in Rust before 1.52.0, the Zip implementation has a panic safety issue. It calls __iterator_get_unchecked() more than once for the same index when the underlying iterator panics (in certain conditions). This bug could lead to a memory safety violation due to an unmet safety requirement for the TrustedRandomAccess trait.
Affected configurations
• rust-lang rust (< 1.52.0)
• fedoraproject fedora 32
• fedoraproject fedora 33
• fedoraproject fedora 34
