CVE-2006-0883 2 Freebsd, Openbsd 2 Freebsd, Openssh 2023-12-10 5.0 MEDIUM N/A
OpenSSH on FreeBSD 5.3 and 5.4, when used with OpenPAM, does not properly handle when a forked child process terminates during PAM authentication, which allows remote attackers to cause a denial of service (client connection refusal) by connecting multiple times to the SSH server, waiting for the password prompt, then disconnecting.
CVE-2005-4351 4 Dragonfly, Freebsd, Linux and 1 more 4 Dragonfly, Freebsd, Linux Kernel and 1 more 2023-12-10 4.3 MEDIUM 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-2006-4435 1 Openbsd 1 Openbsd 2023-12-10 4.9 MEDIUM N/A
OpenBSD 3.8, 3.9, and possibly earlier versions allows context-dependent attackers to cause a denial of service (kernel panic) by allocating more semaphores than the default.
CVE-2005-2666 1 Openbsd 1 Openssh 2023-12-10 1.2 LOW 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-2006-4436 1 Openbsd 1 Openbsd 2023-12-10 5.0 MEDIUM N/A
isakmpd in OpenBSD 3.8, 3.9, and possibly earlier versions, creates Security Associations (SA) with a replay window of size 0 when isakmpd acts as a responder during SA negotiation, which allows remote attackers to replay IPSec packets and bypass the replay protection.
CVE-2005-2798 1 Openbsd 1 Openssh 2023-12-10 5.0 MEDIUM 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-2005-0637 1 Openbsd 1 Openbsd 2023-12-10 5.0 MEDIUM N/A
The copy functions in locore.s such as copyout in OpenBSD 3.5 and 3.6, and possibly other BSD based operating systems, may allow attackers to exceed certain address boundaries and modify kernel memory.
CVE-2006-0225 1 Openbsd 1 Openssh 2023-12-10 4.6 MEDIUM 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-2000-0312 1 Openbsd 1 Openbsd 2023-12-10 7.2 HIGH N/A
cron in OpenBSD 2.5 allows local users to gain root privileges via an argv[] that is not NULL terminated, which is passed to cron's fake popen function.
CVE-2000-0309 1 Openbsd 1 Openbsd 2023-12-10 2.1 LOW N/A
The i386 trace-trap handling in OpenBSD 2.4 with DDB enabled allows a local user to cause a denial of service.
CVE-2004-0084 2 Openbsd, Xfree86 Project 2 Openbsd, X11r6 2023-12-10 10.0 HIGH N/A
Buffer overflow in the ReadFontAlias function in XFree86 4.1.0 to 4.3.0, when using the CopyISOLatin1Lowered function, allows local or remote authenticated users to execute arbitrary code via a malformed entry in the font alias (font.alias) file, a different vulnerability than CVE-2004-0083 and CVE-2004-0106.
CVE-1999-0001 3 Bsdi, Freebsd, Openbsd 3 Bsd Os, Freebsd, Openbsd 2023-12-10 5.0 MEDIUM N/A
ip_input.c in BSD-derived TCP/IP implementations allows remote attackers to cause a denial of service (crash or hang) via crafted packets.
CVE-2003-0787 1 Openbsd 1 Openssh 2023-12-10 7.5 HIGH N/A
The PAM conversation function in OpenSSH 3.7.1 and 3.7.1p1 interprets an array of structures as an array of pointers, which allows attackers to modify the stack and possibly gain privileges.
CVE-2002-1345 3 Ncftp Software, Openbsd, Sun 4 Ncftp, Openbsd, Solaris and 1 more 2023-12-10 5.0 MEDIUM N/A
Directory traversal vulnerabilities in multiple FTP clients on UNIX systems allow remote malicious FTP servers to create or overwrite files as the client user via filenames containing /absolute/path or .. (dot dot) sequences.
CVE-2003-0682 1 Openbsd 1 Openssh 2023-12-10 7.5 HIGH N/A
"Memory bugs" in OpenSSH 3.7.1 and earlier, with unknown impact, a different set of vulnerabilities than CVE-2003-0693 and CVE-2003-0695.
CVE-2004-0417 5 Cvs, Gentoo, Openbsd and 2 more 5 Cvs, Linux, Openbsd and 2 more 2023-12-10 5.0 MEDIUM N/A
Integer overflow in the "Max-dotdot" CVS protocol command (serve_max_dotdot) for CVS 1.12.x through 1.12.8, and 1.11.x through 1.11.16, may allow remote attackers to cause a server crash, which could cause temporary data to remain undeleted and consume disk space.
CVE-2001-0670 4 Bsd, Freebsd, Netbsd and 1 more 4 Bsd, Freebsd, Netbsd and 1 more 2023-12-10 7.5 HIGH N/A
Buffer overflow in BSD line printer daemon (in.lpd or lpd) in various BSD-based operating systems allows remote attackers to execute arbitrary code via an incomplete print job followed by a request to display the printer queue.
CVE-1999-1010 1 Openbsd 1 Openssh 2023-12-10 2.1 LOW 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-2002-2180 1 Openbsd 1 Openbsd 2023-12-10 6.8 MEDIUM N/A
The setitimer(2) system call in OpenBSD 2.0 through 3.1 does not properly check certain arguments, which allows local users to write to kernel memory and possibly gain root privileges, possibly via an integer signedness error.
CVE-2001-1380 1 Openbsd 1 Openssh 2023-12-10 7.5 HIGH N/A
OpenSSH before 2.9.9, while using keypairs and multiple keys of different types in the ~/.ssh/authorized_keys2 file, may not properly handle the "from" option associated with a key, which could allow remote attackers to login from unauthorized IP addresses.
