Ubuntu 13.04 Received Its Last Major Kernel Update

A few days before the announcement for the end of life of Ubuntu 13.04 (Raring Ringtail), Canonical has released the last major update of its soon-to-be unsupported Ubuntu operating system, fixing no more than nine vulnerabilities discovered by various developers in the upstream kernel packages.

The first security issue was a flaw discovered in the Linux kernel’s UDP Fragmentation Offload (UFO), which could allow an unprivileged local user to cause a DoS (Denial of Service) attack; the second one is about multiple integer overflow flaws discovered in Linux kernel’s Alchemy LCD frame- buffer drivers, which could allow an unprivileged local user to gain administrative privileges.

The third security issue is related to a buffer overflow discovered in the Ozmo Devices USB over Wi-Fi devices, which could allow a local user to cause a DoS (Denial of Service) attack; the fourth flaw was discovered in the Linux kernel’s driver for Agere Systems HERMES II Wireless PC cards, and it could allow a local user to gain administrative privileges.
