CVE-2001-1459 1 Openbsd 1 Openssh 2025-04-03 7.5 HIGH N/A
OpenSSH 2.9 and earlier does not initiate a Pluggable Authentication Module (PAM) session if commands are executed with no pty, which allows local users to bypass resource limits (rlimits) set in pam.d.
CVE-2002-0391 4 Freebsd, Microsoft, Openbsd and 1 more 7 Freebsd, Windows 2000, Windows Nt and 4 more 2025-04-03 10.0 HIGH 9.8 CRITICAL
Integer overflow in xdr_array function in RPC servers for operating systems that use libc, glibc, or other code based on SunRPC including dietlibc, allows remote attackers to execute arbitrary code by passing a large number of arguments to xdr_array through RPC services such as rpc.cmsd and dmispd.
CVE-2004-1653 1 Openbsd 1 Openssh 2025-04-03 6.4 MEDIUM N/A
The default configuration for OpenSSH enables AllowTcpForwarding, which could allow remote authenticated users to perform a port bounce, when configured with an anonymous access program such as AnonCVS.
CVE-1999-0396 2 Netbsd, Openbsd 2 Netbsd, Openbsd 2025-04-03 2.6 LOW N/A
A race condition between the select() and accept() calls in NetBSD TCP servers allows remote attackers to cause a denial of service.
CVE-2004-2069 1 Openbsd 1 Openssh 2025-04-03 5.0 MEDIUM N/A
sshd.c in OpenSSH 3.6.1p2 and 3.7.1p2 and possibly other versions, when using privilege separation, does not properly signal the non-privileged process when a session has been terminated after exceeding the LoginGraceTime setting, which leaves the connection open and allows remote attackers to cause a denial of service (connection consumption).
CVE-2004-0175 1 Openbsd 1 Openssh 2025-04-03 4.3 MEDIUM N/A
Directory traversal vulnerability in scp for OpenSSH before 3.4p1 allows remote malicious servers to overwrite arbitrary files. NOTE: this may be a rediscovery of CVE-2000-0992.
CVE-2002-1420 1 Openbsd 1 Openbsd 2025-04-03 7.2 HIGH N/A
Integer signedness error in select() on OpenBSD 3.1 and earlier allows local users to overwrite arbitrary kernel memory via a negative value for the size parameter, which satisfies the boundary check as a signed integer, but is later used as an unsigned integer during a data copying operation.
CVE-2004-0079 23 4d, Apple, Avaya and 20 more 66 Webstar, Mac Os X, Mac Os X Server and 63 more 2025-04-03 5.0 MEDIUM 7.5 HIGH
The do_change_cipher_spec function in OpenSSL 0.9.6c to 0.9.6k, and 0.9.7a to 0.9.7c, allows remote attackers to cause a denial of service (crash) via a crafted SSL/TLS handshake that triggers a null dereference.
CVE-2001-0554 9 Debian, Freebsd, Ibm and 6 more 11 Debian Linux, Freebsd, Aix and 8 more 2025-04-03 10.0 HIGH N/A
Buffer overflow in BSD-based telnetd telnet daemon on various operating systems allows remote attackers to execute arbitrary commands via a set of options including AYT (Are You There), which is not properly handled by the telrcv function.
CVE-2004-0688 4 Openbsd, Suse, X.org and 1 more 4 Openbsd, Suse Linux, X11r6 and 1 more 2025-04-03 7.5 HIGH N/A
Multiple integer overflows in (1) the xpmParseColors function in parse.c, (2) XpmCreateImageFromXpmImage, (3) CreateXImage, (4) ParsePixels, and (5) ParseAndPutPixels for libXpm before 6.8.1 may allow remote attackers to execute arbitrary code via a malformed XPM image file.
CVE-2003-1366 1 Openbsd 1 Openbsd 2025-04-03 3.3 LOW N/A
chpass in OpenBSD 2.0 through 3.2 allows local users to read portions of arbitrary files via a hard link attack on a temporary file used to store user database information.
CVE-2005-0960 1 Openbsd 1 Openbsd 2025-04-03 5.0 MEDIUM N/A
Multiple vulnerabilities in the SACK functionality in (1) tcp_input.c and (2) tcp_usrreq.c OpenBSD 3.5 and 3.6 allow remote attackers to cause a denial of service (memory exhaustion or system crash).
CVE-2005-0740 1 Openbsd 1 Openbsd 2025-04-03 5.0 MEDIUM N/A
The TCP stack (tcp_input.c) in OpenBSD 3.5 and 3.6 allows remote attackers to cause a denial of service (system panic) via crafted values in the TCP timestamp option, which causes invalid arguments to be used when calculating the retransmit timeout.
CVE-2004-0171 2 Freebsd, Openbsd 2 Freebsd, Openbsd 2025-04-03 5.0 MEDIUM N/A
FreeBSD 5.1 and earlier, and Mac OS X before 10.3.4, allows remote attackers to cause a denial of service (resource exhaustion of memory buffers and system crash) via a large number of out-of-sequence TCP packets, which prevents the operating system from creating new connections.
CVE-2004-0492 5 Apache, Hp, Ibm and 2 more 7 Http Server, Virtualvault, Vvos and 4 more 2025-04-03 10.0 HIGH N/A
Heap-based buffer overflow in proxy_util.c for mod_proxy in Apache 1.3.25 to 1.3.31 allows remote attackers to cause a denial of service (process crash) and possibly execute arbitrary code via a negative Content-Length HTTP header field, which causes a large amount of data to be copied.
CVE-2001-0361 2 Openbsd, Ssh 2 Openssh, Ssh 2025-04-03 4.0 MEDIUM N/A
Implementations of SSH version 1.5, including (1) OpenSSH up to version 2.3.0, (2) AppGate, and (3) ssh-1 up to version 1.2.31, in certain configurations, allow a remote attacker to decrypt and/or alter traffic via a "Bleichenbacher attack" on PKCS#1 version 1.5.
CVE-1999-0727 1 Openbsd 1 Openbsd 2025-04-03 5.0 MEDIUM N/A
A kernel leak in the OpenBSD kernel allows IPsec packets to be sent unencrypted.
CVE-2000-0750 3 Netbsd, Openbsd, Redhat 3 Netbsd, Openbsd, Linux 2025-04-03 7.5 HIGH N/A
Buffer overflow in mopd (Maintenance Operations Protocol loader daemon) allows remote attackers to execute arbitrary commands via a long file name.
CVE-2002-2222 2 Freebsd, Openbsd 2 Ports Collection, Openbsd 2025-04-03 5.1 MEDIUM N/A
isakmpd/message.c in isakmpd in FreeBSD before isakmpd-20020403_1, and in OpenBSD 3.1, allows remote attackers to cause a denial of service (crash) by sending Internet Key Exchange (IKE) payloads out of sequence.
CVE-2002-0766 1 Openbsd 1 Openbsd 2025-04-03 7.2 HIGH N/A
OpenBSD 2.9 through 3.1 allows local users to cause a denial of service (resource exhaustion) and gain root privileges by filling the kernel's file descriptor table and closing file descriptors 0, 1, or 2 before executing a privileged process, which is not properly handled when OpenBSD fails to open an alternate descriptor.
