CVE-2001-1559 1 Openbsd 1 Openbsd 2024-02-16 2.1 LOW 5.5 MEDIUM
The uipc system calls (uipc_syscalls.c) in OpenBSD 2.9 and 3.0 provide user mode return instead of versus rval kernel mode values to the fdrelease function, which allows local users to cause a denial of service and trigger a null dereference.
CVE-2004-0221 1 Openbsd 1 Openbsd 2024-02-15 5.0 MEDIUM N/A
isakmpd in OpenBSD 3.4 and earlier allows remote attackers to cause a denial of service (crash) via an ISAKMP packet with a delete payload containing a large number of SPIs, which triggers an out-of-bounds read error, as demonstrated by the Striker ISAKMP Protocol Test Suite.
CVE-2004-0112 24 4d, Apple, Avaya and 21 more 65 Webstar, Mac Os X, Mac Os X Server and 62 more 2024-02-15 5.0 MEDIUM N/A
The SSL/TLS handshaking code in OpenSSL 0.9.7a, 0.9.7b, and 0.9.7c, when using Kerberos ciphersuites, does not properly check the length of Kerberos tickets during a handshake, which allows remote attackers to cause a denial of service (crash) via a crafted SSL/TLS handshake that causes an out-of-bounds read.
CVE-2003-0190 3 Openbsd, Openpkg, Siemens 6 Openssh, Openpkg, Scalance X204rna and 3 more 2024-02-15 5.0 MEDIUM N/A
OpenSSH-portable (OpenSSH) 3.6.1p1 and earlier with PAM support enabled immediately sends an error message when a user does not exist, which allows remote attackers to determine valid usernames via a timing attack.
CVE-2003-0078 3 Freebsd, Openbsd, Openssl 3 Freebsd, Openbsd, Openssl 2024-02-14 5.0 MEDIUM N/A
ssl3_get_record in s3_pkt.c for OpenSSL before 0.9.7a and 0.9.6 before 0.9.6i does not perform a MAC computation if an incorrect block cipher padding is used, which causes an information leak (timing discrepancy) that may make it easier to launch cryptographic attacks that rely on distinguishing between padding and MAC verification errors, possibly leading to extraction of the original plaintext, aka the "Vaudenay timing attack."
CVE-2002-0514 1 Openbsd 1 Openbsd 2024-02-14 5.0 MEDIUM N/A
PF in OpenBSD 3.0 with the return-rst rule sets the TTL to 128 in the RST packet, which allows remote attackers to determine if a port is being filtered because the TTL is different than the default TTL.
CVE-2004-0482 1 Openbsd 1 Openbsd 2024-02-14 4.6 MEDIUM N/A
Multiple integer overflows in (1) procfs_cmdline.c, (2) procfs_fpregs.c, (3) procfs_linux.c, (4) procfs_regs.c, (5) procfs_status.c, and (6) procfs_subr.c in procfs for OpenBSD 3.5 and earlier allow local users to read sensitive kernel memory and possibly perform other unauthorized activities.
CVE-2023-28531 2 Netapp, Openbsd 4 Brocade Fabric Operating System, Hci Bootstrap Os, Solidfire Element Os and 1 more 2024-02-12 N/A 9.8 CRITICAL

CVE-2002-1915 3 Freebsd, Netbsd, Openbsd 3 Freebsd, Netbsd, Openbsd 2024-02-08 2.1 LOW 5.5 MEDIUM
tip on multiple BSD-based operating systems allows local users to cause a denial of service (execution prevention) by using flock() to lock the /var/log/acculog file.
CVE-2002-0391 4 Freebsd, Microsoft, Openbsd and 1 more 7 Freebsd, Windows 2000, Windows Nt and 4 more 2024-02-08 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-2002-0639 1 Openbsd 1 Openssh 2024-02-08 10.0 HIGH 9.8 CRITICAL
Integer overflow in sshd in OpenSSH 2.9.9 through 3.3 allows remote attackers to execute arbitrary code during challenge response authentication (ChallengeResponseAuthentication) when OpenSSH is using SKEY or BSD_AUTH authentication.
CVE-2003-0466 7 Apple, Freebsd, Netbsd and 4 more 8 Mac Os X, Mac Os X Server, Freebsd and 5 more 2024-02-08 10.0 HIGH 9.8 CRITICAL
Off-by-one error in the fb_realpath() function, as derived from the realpath function in BSD, may allow attackers to execute arbitrary code, as demonstrated in wu-ftpd 2.5.0 through 2.6.2 via commands that cause pathnames of length MAXPATHLEN+1 to trigger a buffer overflow, including (1) STOR, (2) RETR, (3) APPE, (4) DELE, (5) MKD, (6) RMD, (7) STOU, or (8) RNTO.
CVE-2002-0083 9 Conectiva, Engardelinux, Immunix and 6 more 11 Linux, Secure Linux, Immunix and 8 more 2024-02-02 10.0 HIGH 9.8 CRITICAL
Off-by-one error in the channel code of OpenSSH 2.0 through 3.0.2 allows local users or remote malicious servers to gain privileges.
CVE-2004-0222 1 Openbsd 1 Openbsd 2024-01-26 5.0 MEDIUM N/A
Multiple memory leaks in isakmpd in OpenBSD 3.4 and earlier allow remote attackers to cause a denial of service (memory exhaustion) via certain ISAKMP packets, as demonstrated by the Striker ISAKMP Protocol Test Suite.
CVE-2004-0079 23 4d, Apple, Avaya and 20 more 66 Webstar, Mac Os X, Mac Os X Server and 63 more 2023-12-28 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-2021-41617 5 Fedoraproject, Netapp, Openbsd and 2 more 14 Fedora, Active Iq Unified Manager, Aff 500f and 11 more 2023-12-26 4.4 MEDIUM 7.0 HIGH
sshd in OpenSSH 6.2 through 8.x before 8.8, when certain non-default configurations are used, allows privilege escalation because supplemental groups are not initialized as expected. Helper programs for AuthorizedKeysCommand and AuthorizedPrincipalsCommand may run with privileges associated with group memberships of the sshd process, if the configuration specifies running the command as a different user.
CVE-2021-28041 4 Fedoraproject, Netapp, Openbsd and 1 more 11 Fedora, Cloud Backup, Hci Compute Node and 8 more 2023-11-07 4.6 MEDIUM 7.1 HIGH
ssh-agent in OpenSSH before 8.5 has a double free that may be relevant in a few less-common scenarios, such as unconstrained agent-socket access on a legacy operating system, or the forwarding of an agent to an attacker-controlled host.
CVE-2019-6111 10 Apache, Canonical, Debian and 7 more 27 Mina Sshd, Ubuntu Linux, Debian Linux and 24 more 2023-11-07 5.8 MEDIUM 5.9 MEDIUM
An issue was discovered in OpenSSH 7.9. Due to the scp implementation being derived from 1983 rcp, the server chooses which files/directories are sent to the client. However, the scp client only performs cursory validation of the object name returned (only directory traversal attacks are prevented). A malicious scp server (or Man-in-The-Middle attacker) can overwrite arbitrary files in the scp client target directory. If recursive operation (-r) is performed, the server can manipulate subdirectories as well (for example, to overwrite the .ssh/authorized_keys file).
CVE-2019-6109 9 Canonical, Debian, Fedoraproject and 6 more 28 Ubuntu Linux, Debian Linux, Fedora and 25 more 2023-11-07 4.0 MEDIUM 6.8 MEDIUM
An issue was discovered in OpenSSH 7.9. Due to missing character encoding in the progress display, a malicious server (or Man-in-The-Middle attacker) can employ crafted object names to manipulate the client output, e.g., by using ANSI control codes to hide additional files being transferred. This affects refresh_progress_meter() in progressmeter.c.
CVE-2016-6515 2 Fedoraproject, Openbsd 2 Fedora, Openssh 2023-11-07 7.8 HIGH 7.5 HIGH
The auth_password function in auth-passwd.c in sshd in OpenSSH before 7.3 does not limit password lengths for password authentication, which allows remote attackers to cause a denial of service (crypt CPU consumption) via a long string.
