Vulnerabilidades

The BSD profil system call allows a local user to modify the internal data space of a program via profiling and execve.

A kernel leak in the OpenBSD kernel allows IPsec packets to be sent unencrypted.

OpenBSD, BSDI, and other Unix operating systems allow users to set chflags and fchflags on character and block devices.

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.

BSD 4.4 based operating systems, when running at security level 1, allow the root user to clear the immutable and append-only flags for files by unmounting the file system and using a file system editor such as fsdb to directly modify the file through a device.

NetBSD allows ARP packets to overwrite static ARP entries.

NetBSD on a multi-homed host allows ARP packets on one network to modify ARP entries on another connected network.

The SVR4 /dev/wabi special device file in NetBSD 1.3.3 and earlier allows a local user to read or write arbitrary files on the disk associated with that device.

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.

Denial of service in "poll" in OpenBSD.

OpenBSD kernel crash through TSS handling, as caused by the crashme program.

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.

umapfs allows local users to gain root privileges by changing their uid through a malicious mount_umap program.

In some cases, NetBSD 1.3.3 mount allows local users to execute programs in some file systems that have the "noexec" flag set.

OpenBSD crash using nlink value in FFS and EXT2FS filesystems.

Buffer overflow in OpenBSD ping.

Remote attackers can cause a system crash through ipintr() in ipq in OpenBSD.

A buffer overflow in lsof allows local users to obtain root privilege.

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

NetBSD netstat command allows local users to access kernel memory.

A system is running a version of software that was replaced with a Trojan Horse at one of its distribution points, such as (1) TCP Wrappers 7.6, (2) util-linux 2.9g, (3) wuarchive ftpd (wuftpd) 2.2 and 2.1f, (4) IRC client (ircII) ircII 2.2.9, (5) OpenSSH 3.4p1, or (6) Sendmail 8.12.6.

Buffer overflow in bootpd on OpenBSD, FreeBSD, and Linux systems via a malformed header type.

KDE allows local users to execute arbitrary commands by setting the KDEDIR environmental variable to modify the search path that KDE uses to locate its executables.

KDE kppp allows local users to create a directory in an arbitrary location via the HOME environmental variable.
