A "programming error" in fast_ipsec in FreeBSD 4.8-RELEASE through 6.1-STABLE and NetBSD 2 through 3 does not properly update the sequence number associated with a Security Association, which allows packets to pass sequence number checks and allows remote attackers to capture IPSec packets and conduct replay attacks. • ftp://ftp.freebsd.org/pub/FreeBSD/CERT/advisories/FreeBSD-SA-06:11.ipsec.asc ftp://ftp.netbsd.org/pub/NetBSD/security/advisories/NetBSD-SA2006-011.txt.asc http://secunia.com/advisories/19366 http://securitytracker.com/id?1015809 http://www.osvdb.org/24068 http://www.securityfocus.com/bid/17191 https://exchange.xforce.ibmcloud.com/vulnerabilities/25398 •

OpenSSH on FreeBSD 5.3 and 5.4, when used with OpenPAM, does not properly handle when a forked child process terminates during PAM authentication, which allows remote attackers to cause a denial of service (client connection refusal) by connecting multiple times to the SSH server, waiting for the password prompt, then disconnecting. • ftp://ftp.freebsd.org/pub/FreeBSD/CERT/advisories/FreeBSD-SA-06:09.openssh.asc http://bugzilla.mindrot.org/show_bug.cgi?id=839 http://securityreason.com/securityalert/520 http://securitytracker.com/id?1015706 http://www.osvdb.org/23797 http://www.securityfocus.com/bid/16892 http://www.vupen.com/english/advisories/2006/0805 https://exchange.xforce.ibmcloud.com/vulnerabilities/25116 • CWE-399: Resource Management Errors •

Selective Acknowledgement (SACK) in FreeBSD 5.3 and 5.4 does not properly handle an incoming selective acknowledgement when there is insufficient memory, which might allow remote attackers to cause a denial of service (infinite loop). • ftp://ftp.freebsd.org/pub/FreeBSD/CERT/advisories/FreeBSD-SA-06:08.sack.asc http://secunia.com/advisories/18696 http://securityreason.com/securityalert/399 http://securitytracker.com/id?1015566 http://www.osvdb.org/22861 http://www.securityfocus.com/bid/16466 http://www.vupen.com/english/advisories/2006/0409 https://exchange.xforce.ibmcloud.com/vulnerabilities/24453 •

A logic error in the IP fragment cache functionality in pf in FreeBSD 5.3, 5.4, and 6.0, and OpenBSD, when a 'scrub fragment crop' or 'scrub fragment drop-ovl' rule is being used, allows remote attackers to cause a denial of service (crash) via crafted packets that cause a packet fragment to be inserted twice. • ftp://ftp.freebsd.org/pub/FreeBSD/CERT/advisories/FreeBSD-SA-06:07.pf.asc ftp://ftp.netbsd.org/pub/NetBSD/security/advisories/NetBSD-SA2006-004.txt.asc http://secunia.com/advisories/18609 http://securitytracker.com/id?1015542 http://www.openbsd.org/cgi-bin/cvsweb/src/sys/net/pf_norm.c.diff?r1=1.103&r2=1.104 http://www.osvdb.org/22732 http://www.securityfocus.com/bid/16375 https://exchange.xforce.ibmcloud.com/vulnerabilities/24337 •

A logic error in FreeBSD kernel 5.4-STABLE and 6.0 causes the kernel to calculate an incorrect buffer length, which causes more data to be copied to userland than intended, which could allow local users to read portions of kernel memory. • ftp://ftp.freebsd.org/pub/FreeBSD/CERT/advisories/FreeBSD-SA-06:06.kmem.asc http://secunia.com/advisories/18599 http://securitytracker.com/id?1015541 http://www.osvdb.org/22731 http://www.securityfocus.com/bid/16373 https://exchange.xforce.ibmcloud.com/vulnerabilities/24340 •
