Description

linux-lts-utopic vulnerabilities It was discovered that virtio networking in the Linux kernel did not handle fragments correctly, leading to kernel memory corruption. A remote attacker could use this to cause a denial of service (system crash) or possibly execute code with administrative privileges. (CVE-2015-5156) Benjamin Randazzo discovered an information leak in the md (multiple device) driver when the bitmap_info.file is disabled. A local privileged attacker could use this to obtain sensitive information from the kernel. (CVE-2015-5697) Marc-André Lureau discovered that the vhost driver did not properly release the userspace provided log file descriptor. A privileged attacker could use this to cause a denial of service (resource exhaustion). (CVE-2015-6252) It was discovered that the Reliable Datagram Sockets (RDS) implementation in the Linux kernel did not verify sockets were properly bound before attempting to send a message, which could cause a NULL pointer dereference. An attacker could use this to cause a denial of service (system crash). (CVE-2015-6937) Ben Hutchings discovered that the Advanced Union Filesystem (aufs) for the Linux kernel did not correctly handle references of memory mapped files from an aufs mount. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code with administrative privileges. (CVE-2015-7312)
