kernel: MTU value is not validated in IPv6 stack causing packet loss

It was found that the Linux kernel's IPv6 network stack did not properly validate the value of the MTU variable when it was set. A remote attacker could potentially use this flaw to disrupt a target system's networking packet loss by setting an invalid MTU value, for example, via a NetworkManager...

NetworkManager: remote DoS using IPv6 RA with bogus MTU

It was discovered that NetworkManager would set device MTUs based on MTU values received in IPv6 RAs Router Advertisements, without sanity checking the MTU value first. A remote attacker could exploit this flaw to create a denial of service attack, by sending a specially crafted IPv6 RA packet to...

Linux kernel IPv6 stack denial of service vulnerability

The Linux kernel is the kernel used by the operating system Linux, released by the Linux Foundation in the United States. A security vulnerability exists in the file net/ipv6/addrconf.c in the IPv6 stack of Linux kernel versions prior to 4.0. As the program fails to check if the new 'MTU' value i...

CVE-2015-0272

GNOME NetworkManager allows remote attackers to cause a denial of service IPv6 traffic disruption via a crafted MTU value in an IPv6 Router Advertisement RA message, a different vulnerability than CVE-2015-8215...

DEBIAN-CVE-2015-8215

net/ipv6/addrconf.c in the IPv6 stack in the Linux kernel before 4.0 does not validate attempted changes to the MTU value, which allows context-dependent attackers to cause a denial of service packet loss via a value that is 1 smaller than the minimum compliant value or 2 larger than the MTU of a...

CVE-2015-8215

CVE-2015-8215 concerns the Linux kernel IPv6 stack (net/ipv6/addrconf.c) where MTU validation is missing. This affects kernel versions before 4.0 and can enable a context-dependent attacker to trigger packet loss through Router Advertisement processing, as the MTU value may be invalid (either bel...

Ubuntu 12.04 LTS : linux vulnerabilities (USN-2792-1)
