CWE-119

Description

In the standard library in Rust before 1.52.0, the Zip implementation calls __iterator_get_unchecked() more than once for the same index (under certain conditions) when next_back() and next() are used together. 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
