Netbsd » Netbsd : Security Vulnerabilities, CVEs, Published In 1999 (Denial of service)

FreeBSD, NetBSD, and OpenBSD allow an attacker to cause a denial of service by creating a large number of socket pairs using the socketpair function, setting a large buffer size via setsockopt, then writing large buffers.

Operating systems with shared memory implementations based on BSD 4.4 code allow a user to conduct a denial of service and bypass memory limits (e.g., as specified with rlimits) using mmap or shmget to allocate memory and cause page faults.

Local users can perform a denial of service in NetBSD 1.3.3 and earlier versions by creating an unusual symbolic link with the ln command, triggering a bug in VFS.

XFree86 xfs command is vulnerable to a symlink attack, allowing local users to create files in restricted directories, possibly allowing them to gain privileges or cause a denial of service.

XFree86 startx command is vulnerable to a symlink attack, allowing local users to create files in restricted directories, possibly allowing them to gain privileges or cause a denial of service.

A race condition between the select() and accept() calls in NetBSD TCP servers allows remote attackers to cause a denial of service.
