se han descubierto una vulnerabilidad en el kernel de una serie de lanzamientos de Ubuntu, que cubre 6.06 LTS a 9.10, incluyendo también las distribuciones Kubuntu, Edubuntu, Xubuntu.
He aquí los hechos, con una frase clave que se destaca:
Mathias Krause discovered that the Linux kernel did not correctly handle missing ELF interpreters. A local attacker could exploit this to cause the system to crash, leading to a denial of service. (CVE-2010-0307)
Marcelo Tosatti discovered that the Linux kernel’s hardware virtualization did not correctly handle reading the /dev/port special device. A local attacker in a guest operating system could issue a specific read that would cause the host system to crash, leading to a denial of service. (CVE-2010-0309)
Sebastian Krahmer discovered that the Linux kernel did not correctly handle netlink connector messages. A local attacker could exploit this to consume kernel memory, leading to a denial of service. (CVE-2010-0410)
Ramon de Carvalho Valle discovered that the Linux kernel did not correctly validate certain memory migration calls. A local attacker could exploit this to read arbitrary kernel memory or cause a system crash, leading to a denial of service. (CVE-2010-0415)
Jermome Marchand and Mikael Pettersson discovered that the Linux kernel did not correctly handle certain futex operations. A local attacker could exploit this to cause a system crash, leading to a denial of service. (CVE-2010-0622, CVE-2010-0623).
Frase clave: "A local attacker"...estos exploits no pueden ser aprovechados de forma remota, es decir, el cielo no está cayendo sobre los usuarios de Linux.
Las actualizaciones están disponibles para distribuciones afectadas.
