HP -UX family of operating systems 11.0.4

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 overflow in Sendmail 5.79 to 8.12.7 allows remote attackers to execute arbitrary code via certain formatted address fields, related to sender and recipient header comments as processed by the crackaddr function of headers.c.

The prescan function in Sendmail 8.12.9 allows remote attackers to execute arbitrary code via buffer overflow attacks, as demonstrated using the parseaddr function in parseaddr.c.

The prescan() function in the address parser (parseaddr.c) in Sendmail before 8.12.9 does not properly handle certain conversions from char and int types, which can cause a length check to be disabled when Sendmail misinterprets an input value as a special "NOCHAR" control value, allowing attackers to cause a denial of service and possibly execute arbitrary code via a buffer overflow attack using messages, a different vulnerability than CVE-2002-1337.

A "potential buffer overflow in ruleset parsing" for Sendmail 8.12.9, when using the nonstandard rulesets (1) recipient (2), final, or (3) mailer-specific envelope recipients, has unknown consequences.

Buffer overflow in stmkfont utility of HP-UX 10.0 through 11.22 allows local users to gain privileges via a long command line argument.

rs.F300 for HP-UX 10.0 through 11.22 uses the PATH environment variable to find and execute programs such as rm while operating at raised privileges, which allows local users to gain privileges by modifying the path to point to a malicious rm program.

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.

Unspecified vulnerability in xntpd of HP-UX 10.20 through 11.11 allows remote attackers to cause a denial of service (hang) via unknown attack vectors.

Vulnerability in passwd for HP-UX 11.00 and 11.11 allows local users to corrupt the password file and cause a denial of service.

HP-UX 11.11 and earlier allows local users to cause a denial of service (kernel deadlock), due to a "file system weakness" that is possibly via an mmap() system call and performing an I/O operation using data from the mapped buffer on the file descriptor for the mapped file.
