CVE-1999-1010 1 Openbsd 1 Openssh 2025-04-03 N/A
An SSH 1.2.27 server allows a client to use the "none" cipher, even if it is not allowed by the server policy.
CVE-1999-0727 1 Openbsd 1 Openbsd 2025-04-03 N/A
A kernel leak in the OpenBSD kernel allows IPsec packets to be sent unencrypted.
CVE-2005-2666 2 Openbsd, Redhat 2 Openssh, Enterprise Linux 2025-04-03 N/A
SSH, as implemented in OpenSSH before 4.0 and possibly other implementations, stores hostnames, IP addresses, and keys in plaintext in the known_hosts file, which makes it easier for an attacker that has compromised an SSH user's account to generate a list of additional targets that are more likely to have the same password or key.
CVE-2005-2798 2 Openbsd, Redhat 2 Openssh, Enterprise Linux 2025-04-03 N/A
sshd in OpenSSH before 4.2, when GSSAPIDelegateCredentials is enabled, allows GSSAPI credentials to be delegated to clients who log in using non-GSSAPI methods, which could cause those credentials to be exposed to untrusted users or hosts.
CVE-2006-0098 1 Openbsd 1 Openbsd 2025-04-03 N/A
The dupfdopen function in sys/kern/kern_descrip.c in OpenBSD 3.7 and 3.8 allows local users to re-open arbitrary files by using setuid programs to access file descriptors using /dev/fd/.
CVE-2006-0225 2 Openbsd, Redhat 2 Openssh, Enterprise Linux 2025-04-03 N/A
scp in OpenSSH 4.2p1 allows attackers to execute arbitrary commands via filenames that contain shell metacharacters or spaces, which are expanded twice.
CVE-2005-4351 4 Dragonfly, Freebsd, Linux and 1 more 4 Dragonfly, Freebsd, Linux Kernel and 1 more 2025-04-03 N/A
The securelevels implementation in FreeBSD 7.0 and earlier, OpenBSD up to 3.8, DragonFly up to 1.2, and Linux up to 2.6.15 allows root users to bypass immutable settings for files by mounting another filesystem that masks the immutable files while the system is running.
CVE-2006-4304 3 Freebsd, Netbsd, Openbsd 3 Freebsd, Netbsd, Openbsd 2025-04-03 N/A
Buffer overflow in the sppp driver in FreeBSD 4.11 through 6.1, NetBSD 2.0 through 4.0 beta before 20060823, and OpenBSD 3.8 and 3.9 before 20060902 allows remote attackers to cause a denial of service (panic), obtain sensitive information, and possibly execute arbitrary code via crafted Link Control Protocol (LCP) packets with an option length that exceeds the overall length, which triggers the overflow in (1) pppoe and (2) ippp. NOTE: this issue was originally incorrectly reported for the ppp driver.
CVE-1999-0482 1 Openbsd 1 Openbsd 2025-04-03 N/A
OpenBSD kernel crash through TSS handling, as caused by the crashme program.
CVE-1999-0724 1 Openbsd 1 Openbsd 2025-04-03 N/A
Buffer overflow in OpenBSD procfs and fdescfs file systems via uio_offset in the readdir() function.
CVE-1999-0674 3 Netbsd, Openbsd, Sun 4 Netbsd, Openbsd, Solaris and 1 more 2025-04-03 N/A
The BSD profil system call allows a local user to modify the internal data space of a program via profiling and execve.
CVE-2024-29937 2 Freebsd, Openbsd 2 Freebsd, Openbsd 2025-03-13 9.8 Critical
NFS in a BSD derived codebase, as used in OpenBSD through 7.4 and FreeBSD through 14.0-RELEASE, allows remote attackers to execute arbitrary code via a bug that is unrelated to memory corruption.
CVE-2023-27567 1 Openbsd 1 Openbsd 2025-03-06 7.5 High
In OpenBSD 7.2, a TCP packet with destination port 0 that matches a pf divert-to rule can crash the kernel.
CVE-2022-48437 1 Openbsd 2 Libressl, Openbsd 2025-02-10 5.3 Medium
An issue was discovered in x509/x509_verify.c in LibreSSL before 3.6.1, and in OpenBSD before 7.2 errata 001. x509_verify_ctx_add_chain does not store errors that occur during leaf certificate verification, and therefore an incorrect error is returned. This behavior occurs when there is an installed verification callback that instructs the verifier to continue upon detecting an invalid certificate.
CVE-2021-46880 1 Openbsd 2 Libressl, Openbsd 2025-02-07 9.8 Critical
x509/x509_verify.c in LibreSSL before 3.4.2, and OpenBSD before 7.0 errata 006, allows authentication bypass because an error for an unverified certificate chain is sometimes discarded.
CVE-2023-35784 1 Openbsd 2 Libressl, Openbsd 2024-12-17 9.8 Critical
A double free or use after free could occur after SSL_clear in OpenBSD 7.2 before errata 026 and 7.3 before errata 004, and in LibreSSL before 3.6.3 and 3.7.x before 3.7.3. NOTE: OpenSSL is not affected.
CVE-2024-11148 1 Openbsd 1 Openbsd 2024-12-06 7.5 High
In OpenBSD 7.4 before errata 006 and OpenBSD 7.3 before errata 020, httpd(8) is vulnerable to a NULL dereference when handling a malformed fastcgi request.
CVE-2023-52558 1 Openbsd 1 Openbsd 2024-11-21 7.5 High
In OpenBSD 7.4 before errata 002 and OpenBSD 7.3 before errata 019, a network buffer that had to be split at certain length that could crash the kernel after receiving specially crafted escape sequences.
CVE-2023-51767 3 Fedoraproject, Openbsd, Redhat 3 Fedora, Openssh, Enterprise Linux 2024-11-21 7.0 High
OpenSSH through 9.6, when common types of DRAM are used, might allow row hammer attacks (for authentication bypass) because the integer value of authenticated in mm_answer_authpassword does not resist flips of a single bit. NOTE: this is applicable to a certain threat model of attacker-victim co-location in which the attacker has user privileges.
CVE-2023-51385 3 Debian, Openbsd, Redhat 5 Debian Linux, Openssh, Enterprise Linux and 2 more 2024-11-21 6.5 Medium
In ssh in OpenSSH before 9.6, OS command injection might occur if a user name or host name has shell metacharacters, and this name is referenced by an expansion token in certain situations. For example, an untrusted Git repository can have a submodule with shell metacharacters in a user name or host name.
