CVE-2011-1927

Linux Kernel < 2.6.39 - Denial of Service via ICMP_TIME_EXCEEDED Packet Handling

Title source: llm

Description

The ip_expire function in net/ipv4/ip_fragment.c in the Linux kernel before 2.6.39 does not properly construct ICMP_TIME_EXCEEDED packets after a timeout, which allows remote attackers to cause a denial of service (invalid pointer dereference) via crafted fragmented packets.
