CVSS: 9.1EPSS: 1%CPEs: 26EXPL: 0CVE-2011-3188 – kernel: net: improve sequence number generation
https://notcve.org/view.php?id=CVE-2011-3188
The (1) IPv4 and (2) IPv6 implementations in the Linux kernel before 3.1 use a modified MD4 algorithm to generate sequence numbers and Fragment Identification values, which makes it easier for remote attackers to cause a denial of service (disrupted networking) or hijack network sessions by predicting these values and sending crafted packets. Las implementaciones de (1) IPv4 y (2) IPv6 en el kernel de Linux antes de v3.1 utiliza una versión modificada de algoritmo MD4 para generar números de secuencia y valores de los fragmentos de identificación, lo que hace que sea más fácil para los atacantes remotos causar una denegación de servicio (red interrumpida) o secuestrar sesiones de red mediante la predicción de estos valores y el envío de paquetes manipulados. • http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=6e5714eaf77d79ae1c8b47e3e040ff5411b717ec http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=bc0b96b54a21246e377122d54569eef71cec535f http://marc.info/?l=bugtraq&m=139447903326211&w=2 http://www.kernel.org/pub/linux/kernel/v3.x/ChangeLog-3.1 http://www.openwall.com/lists/oss-security/2011/08/23/2 https://bugzilla.redhat.com/show_bug.cgi?id=732658 https://github.com/torval •
CVSS: 5.0EPSS: 93%CPEs: 296EXPL: 2CVE-2005-0356 – TCP TIMESTAMPS - Denial of Service
https://notcve.org/view.php?id=CVE-2005-0356
Multiple TCP implementations with Protection Against Wrapped Sequence Numbers (PAWS) with the timestamps option enabled allow remote attackers to cause a denial of service (connection loss) via a spoofed packet with a large timer value, which causes the host to discard later packets because they appear to be too old. • https://www.exploit-db.com/exploits/1008 ftp://ftp.freebsd.org/pub/FreeBSD/CERT/advisories/FreeBSD-SA-05:15.tcp.asc ftp://ftp.sco.com/pub/updates/UnixWare/SCOSA-2005.64/SCOSA-2005.64.txt http://secunia.com/advisories/15393 http://secunia.com/advisories/15417 http://secunia.com/advisories/18222 http://secunia.com/advisories/18662 http://support.avaya.com/elmodocs2/security/ASA-2006-032.htm http://www.cisco.com/warp/public/707/cisco-sn-20050518-tcpts.shtml http:/& •
