The vm-memory rust crate provides a set of traits to decouple VM memory consumers from VM memory providers. An issue was discovered in the default implementations of the `VolatileMemory::{get_atomic_ref, aligned_as_ref, aligned_as_mut, get_ref, get_array_ref}` trait functions, which allows out-of-bounds memory access if the `VolatileMemory::get_slice` function returns a `VolatileSlice` whose length is less than the function’s `count` argument. No implementations of `get_slice` provided in `vm_memory` are affected. Users of custom `VolatileMemory` implementations may be impacted if the custom implementation does not adhere to `get_slice`'s documentation. The issue started in version 0.1.0 but was fixed in version 0.12.2 by inserting a check that verifies that the `VolatileSlice` returned by `get_slice` is of the correct length. Users are advised to upgrade. There are no known workarounds for this issue."},{"lang":"es","value":"En un Monitor de Máquina Virtual (VMM) típico hay varios componentes, como el cargador de arranque, los controladores de dispositivos virtuales, los controladores virtio backend y los controladores vhost, que necesitan acceder a la memoria física de la VM. La caja rust vm-memory proporciona un conjunto de rasgos para desacoplar los consumidores de memoria VM de los proveedores de memoria VM. Se ha descubierto un problema en las implementaciones por defecto de las funciones trait `VolatileMemory::{get_atomic_ref, aligned_as_ref, aligned_as_mut, get_ref, get_array_ref}`, que permite el acceso a memoria fuera de los límites si la función `VolatileMemory::get_slice` devuelve una `VolatileSlice` cuya longitud es menor que el argumento `count` de la función.No afecta a las implementaciones de `get_slice` proporcionadas en `vm_memory`.Los usuarios de implementaciones personalizadas de `VolatileMemory` pueden verse afectados si la implementación personalizada no se adhiere a la documentación de `get_slice`. El problema comenzó en la versión 0.1.0 pero se solucionó en la versión 0.12.2 insertando una comprobación que verifica que la `VolatileSlice` devuelta por `get_slice` tiene la longitud correcta. Se recomienda a los usuarios que actualicen. No se conocen soluciones para este problema."}],"metrics":{"cvssMetricV31":[{"source":"security-advisories@github.com","type":"Secondary","cvssData":{"version":"3.1","vectorString":"CVSS:3.1/AV:L/AC:H/PR:N/UI:R/S:U/C:N/I:N/A:L","baseScore":2.5,"baseSeverity":"LOW","attackVector":"LOCAL","attackComplexity":"HIGH","privilegesRequired":"NONE","userInteraction":"REQUIRED","scope":"UNCHANGED","confidentialityImpact":"NONE","integrityImpact":"NONE","availabilityImpact":"LOW"},"exploitabilityScore":1.0,"impactScore":1.4},{"source":"nvd@nist.gov","type":"Primary","cvssData":{"version":"3.1","vectorString":"CVSS:3.1/AV:L/AC:H/PR:N/UI:R/S:U/C:N/I:N/A:H","baseScore":4.7,"baseSeverity":"MEDIUM","attackVector":"LOCAL","attackComplexity":"HIGH","privilegesRequired":"NONE","userInteraction":"REQUIRED","scope":"UNCHANGED","confidentialityImpact":"NONE","integrityImpact":"NONE","availabilityImpact":"HIGH"},"exploitabilityScore":1.0,"impactScore":3.6}]},"weaknesses":[{"source":"security-advisories@github.com","type":"Secondary","description":[{"lang":"en","value":"CWE-125"}]},{"source":"nvd@nist.gov","type":"Primary","description":[{"lang":"en","value":"CWE-125"}]}],"configurations":[{"nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:a:vm-memory_project:vm-memory:*:*:*:*:*:rust:*:*","versionStartIncluding":"0.1.0","versionEndExcluding":"0.12.2","matchCriteriaId":"48D4C531-5DF9-4E76-8274-F133E20944B4"}]}]}],"references":[{"url":"https://crates.io/crates/vm-memory/0.12.2","source":"security-advisories@github.com","tags":["Product"]},{"url":"https://github.com/rust-vmm/vm-memory/commit/aff1dd4a5259f7deba56692840f7a2d9ca34c9c8","source":"security-advisories@github.com","tags":["Patch"]},{"url":"https://github.com/rust-vmm/vm-memory/security/advisories/GHSA-49hh-fprx-m68g","source":"security-advisories@github.com","tags":["Vendor Advisory"]},{"url":"https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/IPXRXD5VXBZHBGMUM77B52CJJMG7EJGI/","source":"security-advisories@github.com"},{"url":"https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/SYM6CYW2DWRHRAVL2HYTQPXC3J2V77J4/","source":"security-advisories@github.com"},{"url":"https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/XZGJL6BQLU4XCPQLLTW4GSSBTNQXB3TI/","source":"security-advisories@github.com"},{"url":"https://crates.io/crates/vm-memory/0.12.2","source":"af854a3a-2127-422b-91ae-364da2661108","tags":["Product"]},{"url":"https://github.com/rust-vmm/vm-memory/commit/aff1dd4a5259f7deba56692840f7a2d9ca34c9c8","source":"af854a3a-2127-422b-91ae-364da2661108","tags":["Patch"]},{"url":"https://github.com/rust-vmm/vm-memory/security/advisories/GHSA-49hh-fprx-m68g","source":"af854a3a-2127-422b-91ae-364da2661108","tags":["Vendor Advisory"]},{"url":"https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/IPXRXD5VXBZHBGMUM77B52CJJMG7EJGI/","source":"af854a3a-2127-422b-91ae-364da2661108"},{"url":"https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/SYM6CYW2DWRHRAVL2HYTQPXC3J2V77J4/","source":"af854a3a-2127-422b-91ae-364da2661108"},{"url":"https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/XZGJL6BQLU4XCPQLLTW4GSSBTNQXB3TI/","source":"af854a3a-2127-422b-91ae-364da2661108"}]}}]}
