CVE-2013-5209: Freebsd

High severity, CVSS 7.8. EPSS: 2.5% chance of exploitation in the next 30 days.

The sctp_send_initiate_ack function in sys/netinet/sctp_output.c in the SCTP implementation in the kernel in FreeBSD 8.3 through 9.2-PRERELEASE does not properly initialize the state-cookie data structure, which allows remote attackers to obtain sensitive information from kernel stack memory by reading packet data in INIT-ACK chunks.

Affected products

• Freebsd Freebsd: version 8.3 only; version 9.0 only; version 9.1 only; version 9.2 only
