Descriptions

An off-by-one error flaw was found in the udevListInterfacesByStatus() function in libvirt when the number of interfaces exceeds the size of the `names` array. This issue can be reproduced by sending specially crafted data to the libvirt daemon, allowing an unprivileged client to perform a denial of service attack by causing the libvirt daemon to crash.

Se encontró una falla de error uno por uno en la función udevListInterfacesByStatus() en libvirt cuando el número de interfaces excede el tamaño de la matriz `names`. Este problema se puede reproducir enviando datos especialmente manipulados al daemon libvirt, lo que permite que un cliente sin privilegios realice un ataque de denegación de servicio provocando que el daemon libvirt falle.

Alexander Kuznetsov discovered that libvirt incorrectly handled certain API calls. An attacker could possibly use this issue to cause libvirt to crash, resulting in a denial of service. It was discovered that libvirt incorrectly handled certain RPC library API calls. An attacker could possibly use this issue to cause libvirt to crash, resulting in a denial of service. It was discovered that libvirt incorrectly handled detaching certain host interfaces. An attacker could possibly use this issue to cause libvirt to crash, resulting in a denial of service.

*Credits: Red Hat would like to thank Alexander Kuznetsov for reporting this issue.
