| CVE-2022-27882 | 1 Openbsd | 1 Openbsd | 2022-05-12 | 7.5 High |
| slaacd in OpenBSD 6.9 and 7.0 before 2022-03-22 has an integer signedness error and resultant heap-based buffer overflow triggerable by a crafted IPv6 router advertisement. NOTE: privilege separation and pledge can prevent exploitation. | ||||
| CVE-2022-27881 | 1 Openbsd | 1 Openbsd | 2022-05-12 | 7.5 High |
| engine.c in slaacd in OpenBSD 6.9 and 7.0 before 2022-02-21 has a buffer overflow triggerable by an IPv6 router advertisement with more than seven nameservers. NOTE: privilege separation and pledge can prevent exploitation. | ||||
| CVE-2001-0554 | 9 Debian, Freebsd, Ibm and 6 more | 11 Debian Linux, Freebsd, Aix and 8 more | 2022-01-21 | 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-2020-16088 | 1 Openbsd | 1 Openbsd | 2022-01-04 | 9.8 Critical |
| iked in OpenIKED, as used in OpenBSD through 6.7, allows authentication bypass because ca.c has the wrong logic for checking whether a public key matches. | ||||
| CVE-2020-26142 | 1 Openbsd | 1 Openbsd | 2021-12-03 | 5.3 Medium |
| An issue was discovered in the kernel in OpenBSD 6.6. The WEP, WPA, WPA2, and WPA3 implementations treat fragmented frames as full frames. An adversary can abuse this to inject arbitrary network packets, independent of the network configuration. | ||||
| CVE-2004-0081 | 23 4d, Apple, Avaya and 20 more | 66 Webstar, Mac Os X, Mac Os X Server and 63 more | 2021-11-08 | N/A |
| OpenSSL 0.9.6 before 0.9.6d does not properly handle unknown message types, which allows remote attackers to cause a denial of service (infinite loop), as demonstrated using the Codenomicon TLS Test Tool. | ||||
| CVE-2010-4816 | 1 Openbsd | 1 Openbsd | 2021-09-20 | 7.5 High |
| It was found in FreeBSD 8.0, 6.3 and 4.9, and OpenBSD 4.6 that a null pointer dereference in ftpd/popen.c may lead to remote denial of service of the ftpd service. | ||||
| CVE-2019-8460 | 1 Openbsd | 1 Openbsd | 2021-08-02 | 7.5 High |
| OpenBSD kernel version <= 6.5 can be forced to create long chains of TCP SACK holes that causes very expensive calls to tcp_sack_option() for every incoming SACK packet which can lead to a denial of service. | ||||
| CVE-2019-19519 | 1 Openbsd | 1 Openbsd | 2021-07-21 | 7.8 High |
| In OpenBSD 6.6, local users can use the su -L option to achieve any login class (often excluding root) because there is a logic error in the main function in su/su.c. | ||||
| CVE-2019-6724 | 4 Apple, Barracuda, Linux and 1 more | 4 Mac Os X, Vpn Client, Linux Kernel and 1 more | 2020-08-24 | N/A |
| The barracudavpn component of the Barracuda VPN Client prior to version 5.0.2.7 for Linux, macOS, and OpenBSD runs as a privileged process and can allow an unprivileged local attacker to load a malicious library, resulting in arbitrary code executing as root. | ||||
| CVE-2019-19522 | 1 Openbsd | 1 Openbsd | 2020-08-24 | 7.8 High |
| OpenBSD 6.6, in a non-default configuration where S/Key or YubiKey authentication is enabled, allows local users to become root by leveraging membership in the auth group. This occurs because root's file can be written to /etc/skey or /var/db/yubikey, and need not be owned by root. | ||||
| CVE-2019-19520 | 1 Openbsd | 1 Openbsd | 2020-08-24 | 7.8 High |
| xlock in OpenBSD 6.6 allows local users to gain the privileges of the auth group by providing a LIBGL_DRIVERS_PATH environment variable, because xenocara/lib/mesa/src/loader/loader.c mishandles dlopen. | ||||
| CVE-2011-3336 | 4 Apple, Freebsd, Openbsd and 1 more | 4 Mac Os X, Freebsd, Openbsd and 1 more | 2020-02-18 | 7.5 High |
| regcomp in the BSD implementation of libc is vulnerable to denial of service due to stack exhaustion. | ||||
| CVE-2001-0247 | 5 Freebsd, Mit, Netbsd and 2 more | 5 Freebsd, Kerberos 5, Netbsd and 2 more | 2020-01-21 | N/A |
| Buffer overflows in BSD-based FTP servers allows remote attackers to execute arbitrary commands via a long pattern string containing a {} sequence, as seen in (1) g_opendir, (2) g_lstat, (3) g_stat, and (4) the glob0 buffer as used in the glob functions glob2 and glob3. | ||||
| CVE-2003-0028 | 10 Cray, Freebsd, Gnu and 7 more | 13 Unicos, Freebsd, Glibc and 10 more | 2020-01-21 | N/A |
| Integer overflow in the xdrmem_getbytes() function, and possibly other functions, of XDR (external data representation) libraries derived from SunRPC, including libnsl, libc, glibc, and dietlibc, allows remote attackers to execute arbitrary code via certain integer values in length fields, a different vulnerability than CVE-2002-0391. | ||||
| CVE-2012-1577 | 3 Debian, Dietlibc Project, Openbsd | 3 Debian Linux, Dietlibc, Openbsd | 2019-12-17 | 9.8 Critical |
| lib/libc/stdlib/random.c in OpenBSD returns 0 when seeded with 0. | ||||
| CVE-2019-19521 | 1 Openbsd | 1 Openbsd | 2019-12-12 | 9.8 Critical |
| libc in OpenBSD 6.6 allows authentication bypass via the -schallenge username, as demonstrated by smtpd, ldapd, or radiusd. This is related to gen/auth_subr.c and gen/authenticate.c in libc (and login/login.c and xenocara/app/xenodm/greeter/verify.c). | ||||
| CVE-2017-1000372 | 1 Openbsd | 1 Openbsd | 2019-10-03 | N/A |
| A flaw exists in OpenBSD's implementation of the stack guard page that allows attackers to bypass it resulting in arbitrary code execution using setuid binaries such as /usr/bin/at. This affects OpenBSD 6.1 and possibly earlier versions. | ||||
| CVE-2017-5850 | 1 Openbsd | 1 Openbsd | 2019-10-03 | N/A |
| httpd in OpenBSD allows remote attackers to cause a denial of service (memory consumption) via a series of requests for a large file using an HTTP Range header. | ||||
| CVE-2005-0356 | 9 Alaxala, Cisco, F5 and 6 more | 76 Alaxala Networks, Agent Desktop, Aironet Ap1200 and 73 more | 2019-04-30 | N/A |
| Multiple TCP implementations with Protection Against Wrapped Sequence Numbers (PAWS) with the timestamps option enabled allow remote attackers to cause a denial of service (connection loss) via a spoofed packet with a large timer value, which causes the host to discard later packets because they appear to be too old. | ||||
