Description
This security bulletin contains information about 1 security vulnerability.
1) Resource management error (CVE-ID: CVE-2013-4163)
The vulnerability allows a remote non-authenticated attacker to perform a denial of service (DoS) attack.
The ip6_append_data_mtu function in net/ipv6/ip6_output.c in the IPv6 implementation in the Linux kernel through 3.10.3 does not properly maintain information about whether the IPV6_MTU setsockopt option had been specified, which allows local users to cause a denial of service (BUG and system crash) via a crafted application that uses the UDP_CORK option in a setsockopt system call.
Remediation
Install update from vendor's website.
