Buffer overflow in login in various System V based operating systems allows remote attackers to execute arbitrary commands via a large number of arguments through services such as telnet and rlogin.
Buffer overflows and other vulnerabilities in multiple Common Desktop Environment (CDE) modules in HP-UX 10.10 through 11.11 allow attackers to cause a denial of service and possibly gain additional privileges.
Multiple TCP implementations could allow remote attackers to cause a denial of service (bandwidth and CPU exhaustion) by setting the maximum segment size (MSS) to a very small number and requesting large amounts of data, which generates more packets with less TCP-level data that amplify network traffic and consume more server CPU to process.
