Описание
Integer overflow in the ping_init_sock function in net/ipv4/ping.c in the Linux kernel through 3.14.1 allows local users to cause a denial of service (use-after-free and system crash) or possibly gain privileges via a crafted application that leverages an improperly managed reference counter.
A use-after-free flaw was found in the way the ping_init_sock() function of the Linux kernel handled the group_info reference counter. A local, unprivileged user could use this flaw to crash the system or, potentially, escalate their privileges on the system.
Отчет
This issue does not affect Linux kernel packages as shipped with Red Hat Enterprise Linux 5.
