CVSS: 9.8EPSS: 1%CPEs: 4EXPL: 1CVE-2021-31162 – rust: double free in Vec::from_iter function if freeing the element panics
https://notcve.org/view.php?id=CVE-2021-31162
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: 1EXPL: 1CVE-2020-36317 – rust: memory safety violation in String::retain()
https://notcve.org/view.php?id=CVE-2020-36317
In the standard library in Rust before 1.49.0, String::retain() function has a panic safety problem. It allows creation of a non-UTF-8 Rust string when the provided closure panics. This bug could result in a memory safety violation when other string APIs assume that UTF-8 encoding is used on the same string. En la biblioteca estándar en Rust versiones anteriores a 1.49.0, la función String::retener() presenta un problema de seguridad de pánico. Permite una creación de una cadena Rust que no sea UTF-8 cuando el cierre provisto entra en pánico. • https://github.com/rust-lang/rust/issues/78498 https://github.com/rust-lang/rust/pull/78499 https://access.redhat.com/security/cve/CVE-2020-36317 https://bugzilla.redhat.com/show_bug.cgi?id=1949189 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-787: Out-of-bounds Write •

https://notcve.org/view.php?id=CVE-2020-36318
In the standard library in Rust before 1.49.0, VecDeque::make_contiguous has a bug that pops the same element more than once under certain condition. This bug could result in a use-after-free or double free. En la biblioteca estándar de Rust versiones anteriores a 1.49.0, la función VecDeque::make_contiguous presenta un bug que muestra el mismo elemento más de una vez bajo determinadas condiciones. Este bug podría resultar en un uso de la memoria previamente liberada o una doble liberación • https://github.com/rust-lang/rust/issues/79808 https://github.com/rust-lang/rust/pull/79814 https://access.redhat.com/security/cve/CVE-2020-36318 https://bugzilla.redhat.com/show_bug.cgi?id=1949192 • 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 •
CVSS: 9.8EPSS: 1%CPEs: 4EXPL: 1CVE-2021-28879 – rust: integer overflow in the Zip implementation can lead to a buffer overflow
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 •
