Category:	Amazon Linux Local Security Checks
Title:	Amazon Linux: Security Advisory (ALAS-2013-252)
Summary:	The remote host is missing an update for the 'kernel' package(s) announced via the ALAS-2013-252 advisory.
Description:	Summary: The remote host is missing an update for the 'kernel' package(s) announced via the ALAS-2013-252 advisory. Vulnerability Insight: The Linux kernel before 3.12, when UDP Fragmentation Offload (UFO) is enabled, does not properly initialize certain data structures, which allows local users to cause a denial of service (memory corruption and system crash) or possibly gain privileges via a crafted application that uses the UDP_CORK option in a setsockopt system call and sends both short and long packets, related to the ip_ufo_append_data function in net/ipv4/ip_output.c and the ip6_ufo_append_data function in net/ipv6/ip6_output.c. The skb_flow_dissect function in net/core/flow_dissector.c in the Linux kernel through 3.12 allows remote attackers to cause a denial of service (infinite loop) via a small value in the IHL field of a packet with IPIP encapsulation. Affected Software/OS: 'kernel' package(s) on Amazon Linux. Solution: Please install the updated package(s). CVSS Score: 7.1 CVSS Vector: AV:N/AC:M/Au:N/C:N/I:N/A:C
