In the standard library in Rust before 1.52.0, a double free can occur in the Vec::from_iter function if freeing the element panics. En la biblioteca estándar de Rust versiones anteriores a 1.52.0, se puede producir una doble liberación en la función Vec::from_iter si se libera los pánicos del elemento • https://github.com/rust-lang/rust/issues/83618 https://github.com/rust-lang/rust/pull/83629 https://github.com/rust-lang/rust/pull/84603 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/CZ337CM4GFJLRDFVQCGC7J25V65JXOG5 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/TFUO3URYCO73D2Q4WYJBWAMJWGGVXQO4 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/VZG65GUW6Z2CYOQHF7T3TB5CZKIX6ZJE https://security. • CWE-415: Double Free CWE-416: Use After Free •

CVSS: 7.5EPSS: 0%CPEs: 4EXPL: 1CVE-2021-28878 – rust: memory safety violation in Zip implementation when next_back() and next() are used together
https://notcve.org/view.php?id=CVE-2021-28878
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. En la biblioteca estándar en Rust versiones anteriores a 1.52.0, la implementación de Zip llama a la función __iterator_get_unchecked() más de una vez para el mismo índice (bajo determinadas condiciones) cuando las funciones next_back() y next() son usadas juntas. Este bug podría conllevar a una violación de seguridad de la memoria debido a un requisito de seguridad no cumplido para el rasgo TrustedRandomAccess • https://github.com/rust-lang/rust/issues/82291 https://github.com/rust-lang/rust/pull/82292 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/CZ337CM4GFJLRDFVQCGC7J25V65JXOG5 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/TFUO3URYCO73D2Q4WYJBWAMJWGGVXQO4 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/VZG65GUW6Z2CYOQHF7T3TB5CZKIX6ZJE https://security.gentoo.org/glsa/202210-09 https://access.redhat • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •

https://notcve.org/view.php?id=CVE-2021-28879
In the standard library in Rust before 1.52.0, the Zip implementation can report an incorrect size due to an integer overflow. This bug can lead to a buffer overflow when a consumed Zip iterator is used again. En la biblioteca estándar de Rust versiones anteriores a 1.52.0, la implementación de Zip puede reportar un tamaño incorrecto debido a un desbordamiento de enteros. Este bug puede conllevar a un desbordamiento del búfer cuando un iterador Zip consumido es usado nuevamente • https://github.com/rust-lang/rust/issues/82282 https://github.com/rust-lang/rust/pull/82289 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/CZ337CM4GFJLRDFVQCGC7J25V65JXOG5 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/TFUO3URYCO73D2Q4WYJBWAMJWGGVXQO4 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/VZG65GUW6Z2CYOQHF7T3TB5CZKIX6ZJE https://security.gentoo.org/glsa/202210-09 https://access.redhat • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-190: Integer Overflow or Wraparound •
CVSS: 5.3EPSS: 0%CPEs: 4EXPL: 1CVE-2021-28876 – rust: panic safety issue in Zip implementation
https://notcve.org/view.php?id=CVE-2021-28876
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. En la biblioteca estándar de Rust versiones anteriores a 1.52.0, la implementación de Zip presenta un problema de seguridad de pánico. Llama a la función __iterator_get_unchecked() más de una vez para el mismo índice cuando el iterador subyacente entra en pánico (en determinadas condiciones). • https://github.com/rust-lang/rust/issues/81740 https://github.com/rust-lang/rust/pull/81741 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/CZ337CM4GFJLRDFVQCGC7J25V65JXOG5 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/TFUO3URYCO73D2Q4WYJBWAMJWGGVXQO4 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/VZG65GUW6Z2CYOQHF7T3TB5CZKIX6ZJE https://security.gentoo.org/glsa/202210-09 https://access.redhat • CWE-755: Improper Handling of Exceptional Conditions •
