SUSE CVE-2001-0328

TCP implementations that use random increments for initial sequence numbers ISN can allow remote attackers to perform session hijacking or disruption by injecting a flood of packets with a range of ISN values, one of which may match the expected ISN...

SUSE 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 appe...

SUSE CVE-2020-35685

An issue was discovered in HCC Nichestack 3.0. The code that generates Initial Sequence Numbers ISNs for TCP connections derives the ISN from an insufficiently random source. As a result, an attacker may be able to determine the ISN of current and future TCP connections and either hijack existing...

Zuken Elmic KASAGO uses insufficient random values for TCP Initial Sequence Numbers

Overview Zuken Elmic KASAGO, TCP/IP protocol stack for embedded systems, uses its own random number generator function when generating TCP initial sequence numbers, which leads to use insufficient random values CWE-330. Zuken Elmic reported this vulnerability to JPCERT/CC to notify users of its...
