The frag3 preprocessor in Sourcefire Snort 2.4.3 does not properly reassemble certain fragmented packets with IP options, which allows remote attackers to evade detection of certain attacks, possibly related to IP option lengths. • http://secunia.com/advisories/18959 http://www.securityfocus.com/archive/1/425290/100/0/threaded http://www.securityfocus.com/bid/16705 https://exchange.xforce.ibmcloud.com/vulnerabilities/24811 •

The DecodeTCPOptions function in decode.c in Snort before 2.3.0, when printing TCP/IP options using FAST output or verbose mode, allows remote attackers to cause a denial of service (crash) via packets with invalid TCP/IP options, which trigger a null dereference. • https://www.exploit-db.com/exploits/25046 https://www.exploit-db.com/exploits/25047 http://secunia.com/advisories/13664 http://securitytracker.com/id?1012656 http://taosecurity.blogspot.com/2004/12/details-on-snort-dos-condition-you-may.html http://www.frsirt.com/exploits/20041222.angelDust.c.php http://www.osvdb.org/12578 http://www.securiteam.com/exploits/6X00L20C0S.html http://www.securityfocus.com/bid/12084 http://www.snort.org/arc_news https://exchange.xforce.ibmclou •

Integer overflow in the TCP stream reassembly module (stream4) for Snort 2.0 and earlier allows remote attackers to execute arbitrary code via large sequence numbers in packets, which enable a heap-based buffer overflow. Desbordamiento de enteros en el modulo de reensamblaje TCP (stream4) de Snort 2.0 y anteriores permite a atacantes remotos ejecutar código arbitrario mediante números de secuencia largo en paquetes, lo que permite un desbordamiento de búfer basado en el montón. • https://www.exploit-db.com/exploits/18 http://marc.info/?l=bugtraq&m=105043563016235&w=2 http://marc.info/?l=bugtraq&m=105103586927007&w=2 http://marc.info/?l=bugtraq&m=105111217731583&w=2 http://marc.info/?l=bugtraq&m=105154530427824&w=2 http://marc.info/? •
