CVE-2019-19519 1 Openbsd 1 Openbsd 2021-07-21 4.6 MEDIUM 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-2019-25049 2 Linux, Openbsd 2 Linux Kernel, Libressl 2021-07-08 5.8 MEDIUM 7.1 HIGH
LibreSSL 2.9.1 through 3.2.1 has an out-of-bounds read in asn1_item_print_ctx (called from asn1_template_print_ctx).
CVE-2019-25048 2 Linux, Openbsd 2 Linux Kernel, Libressl 2021-07-08 5.8 MEDIUM 7.1 HIGH
LibreSSL 2.9.1 through 3.2.1 has a heap-based buffer over-read in do_print_ex (called from asn1_item_print_ctx and ASN1_item_print).
CVE-2004-0492 5 Apache, Hp, Ibm and 2 more 7 Http Server, Virtualvault, Vvos and 4 more 2021-06-06 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-2007-2768 2 Netapp, Openbsd 5 Hci Management Node, Hci Storage Node, Solidfire and 2 more 2021-04-01 4.3 MEDIUM N/A
OpenSSH, when using OPIE (One-Time Passwords in Everything) for PAM, allows remote attackers to determine the existence of certain user accounts, which displays a different response if the user account exists and is configured to use one-time passwords (OTP), a similar issue to CVE-2007-2243.
CVE-2019-6724 4 Apple, Barracuda, Linux and 1 more 4 Mac Os X, Vpn Client, Linux Kernel and 1 more 2020-08-24 7.2 HIGH 7.8 HIGH
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 7.2 HIGH 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 4.6 MEDIUM 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-2020-12062 1 Openbsd 1 Openssh 2020-06-04 5.0 MEDIUM 7.5 HIGH
** DISPUTED ** The scp client in OpenSSH 8.2 incorrectly sends duplicate responses to the server upon a utimes system call failure, which allows a malicious unprivileged user on the remote server to overwrite arbitrary files in the client's download directory by creating a crafted subdirectory anywhere on the remote server. The victim must use the command scp -rp to download a file hierarchy containing, anywhere inside, this crafted subdirectory. NOTE: the vendor points out that "this attack can achieve no more than a hostile peer is already able to achieve within the scp protocol" and "utimes does not fail under normal circumstances."
CVE-2011-3336 4 Apple, Freebsd, Openbsd and 1 more 4 Mac Os X, Freebsd, Openbsd and 1 more 2020-02-18 7.8 HIGH 7.5 HIGH
regcomp in the BSD implementation of libc is vulnerable to denial of service due to stack exhaustion.
CVE-2015-5334 2 Openbsd, Opensuse 2 Libressl, Opensuse 2020-01-30 7.5 HIGH 9.8 CRITICAL
Off-by-one error in the OBJ_obj2txt function in LibreSSL before 2.3.1 allows remote attackers to cause a denial of service (program crash) or possible execute arbitrary code via a crafted X.509 certificate, which triggers a stack-based buffer overflow. Note: this vulnerability exists because of an incorrect fix for CVE-2014-3508.
CVE-2015-5333 2 Openbsd, Opensuse 2 Libressl, Opensuse 2020-01-29 5.0 MEDIUM 7.5 HIGH
Memory leak in the OBJ_obj2txt function in LibreSSL before 2.3.1 allows remote attackers to cause a denial of service (memory consumption) via a large number of ASN.1 object identifiers in X.509 certificates.
CVE-2001-0247 5 Freebsd, Mit, Netbsd and 2 more 5 Freebsd, Kerberos 5, Netbsd and 2 more 2020-01-21 10.0 HIGH 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 7.5 HIGH 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-2012-5663 1 Openbsd 1 Textproc\/isearch 2020-01-10 5.0 MEDIUM 7.5 HIGH
The isearch package (textproc/isearch) before 1.47.01nb1 uses the tempnam() function to create insecure temporary files into a publicly-writable area (/tmp).
CVE-2012-1577 3 Debian, Dietlibc Project, Openbsd 3 Debian Linux, Dietlibc, Openbsd 2019-12-17 7.5 HIGH 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 7.5 HIGH 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-2013-4548 1 Openbsd 1 Openssh 2019-10-09 6.0 MEDIUM N/A
The mm_newkeys_from_blob function in monitor_wrap.c in sshd in OpenSSH 6.2 and 6.3, when an AES-GCM cipher is used, does not properly initialize memory for a MAC context data structure, which allows remote authenticated users to bypass intended ForceCommand and login-shell restrictions via packet data that provides a crafted callback address.
CVE-2017-8301 1 Openbsd 1 Libressl 2019-10-02 2.6 LOW 5.3 MEDIUM
LibreSSL 2.5.1 to 2.5.3 lacks TLS certificate verification if SSL_get_verify_result is relied upon for a later check of a verification result, in a use case where a user-provided verification callback returns 1, as demonstrated by acceptance of invalid certificates by nginx.
CVE-2017-1000372 1 Openbsd 1 Openbsd 2019-10-02 7.5 HIGH 9.8 CRITICAL
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.
