BsdiCVEs & Vulnerabilities

The TCP implementation in (1) Linux, (2) platforms based on BSD Unix, (3) Microsoft Windows, (4) Cisco products, and probably other operating systems allows remote attackers to cause a denial of service (connection queue exhaustion) via multiple vectors that manipulate information in the TCP state table, as demonstrated by sockstress.

Buffer overflow in Unix-to-Unix Copy Protocol (UUCP) in BSDI BSD/OS 3.0 through 4.2 allows local users to execute arbitrary code via a long command line argument.

Cyrus 2.0.15, 2.0.16, and 1.6.24 on BSDi 4.2, with IMAP enabled, allows remote attackers to cause a denial of service (hang) using PHP IMAP clients.

Vulnerability in a system call in BSDI 3.0 and 3.1 allows local users to cause a denial of service (reboot) in the kernel via a particular sequence of instructions.

rcvtty in BSD 3.0 and 4.0 does not properly drop privileges before executing a script, which allows local attackers to gain privileges by specifying an alternate Trojan horse script on the command line.

ip_input.c in BSD-derived TCP/IP implementations allows remote attackers to cause a denial of service (crash or hang) via crafted packets.

When BSDI patches for Gauntlet 5.0 BSDI are installed in a particular order, Gauntlet allows remote attackers to bypass firewall access restrictions, and does not log the activities.

Denial of service in WU-FTPD via the SITE NEWER command, which does not free memory properly.

Buffer overflow in WU-FTPD and related FTP servers allows remote attackers to gain root privileges via macro variables in a message file.

Buffer overflow in Berkeley automounter daemon (amd) logging facility provided in the Linux am-utils package and others.

Denial of service in BSDi Symmetric Multiprocessing (SMP) when an fstat call is made when the system has a high CPU load.

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

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

IP fragmentation denial of service in FreeBSD allows a remote attacker to cause a crash.

Buffer overflow in NFS mountd gives root access to remote attackers, mostly in Linux systems.

Inverse query buffer overflow in BIND 4.9 and BIND 8 Releases.

FreeBSD mmap function allows users to modify append-only or immutable files.

mmap function in BSD allows local attackers in the kmem group to modify memory through devices.

The system configuration control (sysctl) facility in BSD based operating systems OpenBSD 2.2 and earlier, and FreeBSD 2.2.5 and earlier, does not properly restrict source routed packets even when the (1) dosourceroute or (2) forwarding variables are set, which allows remote attackers to spoof TCP connections.

File creation and deletion, and remote execution, in the BSD line printer daemon (lpd).

DNS cache poisoning via BIND, by predictable query IDs.

Buffer overflow in suidperl (sperl), Perl 4.x and 5.x.

Buffer overflow in Xt library of X Windowing System allows local users to execute commands with root privileges.

Buffer overflow in xlock program allows local users to execute commands as root.

Buffer overflow in University of Washington's implementation of IMAP and POP servers.

NFS cache poisoning.

Buffer overflow of rlogin program using TERM environmental variable.

MIME conversion buffer overflow in sendmail versions 8.8.3 and 8.8.4.

Buffer overflow in Vixie Cron library up to version 3.0 allows local users to obtain root access via a long environmental variable.

Sendmail decode alias can be used to overwrite sensitive files.

Command execution via shell metachars in INN daemon (innd) 1.5 using "newgroup" and "rmgroup" control messages, and others.

Sendmail allows local users to write to a file and gain group permissions via a .forward or :include: file.

Local users can start Sendmail in daemon mode and gain root privileges.

Buffer overflow in lpr, as used in BSD-based systems including Linux, allows local users to execute arbitrary code as root via a long -C (classification) command line option.

Buffer overflow and denial of service in Sendmail 8.7.5 and earlier through GECOS field gives root access to local users.

Local user gains root privileges via buffer overflow in rdist, via lookup() function.

Local user gains root privileges via buffer overflow in rdist, via expstr() function.

pcnfsd (aka rpc.pcnfsd) allows local users to change file permissions, or execute arbitrary commands through arguments in the RPC call.

Buffer overflow in syslog utility allows local or remote attackers to gain root privileges.
