Red Hat Security Advisory 2015-1787-01

Posted Sep 17, 2015

Authored by Red Hat | Site access.redhat.com

Red Hat Security Advisory 2015-1787-01 - The kernel-rt packages contain the Linux kernel, the core of any Linux operating system. Two flaws were found in the way the Linux kernel's networking implementation handled UDP packets with incorrect checksum values. A remote attacker could potentially use these flaws to trigger an infinite loop in the kernel, resulting in a denial of service on the system, or cause a denial of service in applications using the edge triggered epoll functionality. A flaw was found in the way the Linux kernel's ext4 file system handled the "page size > block size" condition when the fallocate zero range functionality was used. A local attacker could use this flaw to crash the system.
