CVE-2016-10708 | 4 Canonical, Debian, Netapp and 1 more | 12 Ubuntu Linux, Debian Linux, Cloud Backup and 9 more | 2023-11-07 | 5.0 MEDIUM | 7.5 HIGH |
sshd in OpenSSH before 7.4 allows remote attackers to cause a denial of service (NULL pointer dereference and daemon crash) via an out-of-sequence NEWKEYS message, as demonstrated by Honggfuzz, related to kex.c and packet.c. | |||||
CVE-2016-10012 | 1 Openbsd | 1 Openssh | 2023-11-07 | 7.2 HIGH | 7.8 HIGH |
The shared memory manager (associated with pre-authentication compression) in sshd in OpenSSH before 7.4 does not ensure that a bounds check is enforced by all compilers, which might allows local users to gain privileges by leveraging access to a sandboxed privilege-separation process, related to the m_zback and m_zlib data structures. | |||||
CVE-2012-0814 | 1 Openbsd | 1 Openssh | 2023-11-07 | 3.5 LOW | N/A |
The auth_parse_options function in auth-options.c in sshd in OpenSSH before 5.7 provides debug messages containing authorized_keys command options, which allows remote authenticated users to obtain potentially sensitive information by reading these messages, as demonstrated by the shared user account required by Gitolite. NOTE: this can cross privilege boundaries because a user account may intentionally have no shell or filesystem access, and therefore may have no supported way to read an authorized_keys file in its own home directory. | |||||
CVE-2011-2168 | 1 Openbsd | 1 Openbsd | 2023-11-07 | 5.0 MEDIUM | N/A |
Multiple integer overflows in the glob implementation in libc in OpenBSD before 4.9 might allow context-dependent attackers to have an unspecified impact via a crafted string, related to the GLOB_APPEND and GLOB_DOOFFS flags, a different issue than CVE-2011-0418. | |||||
CVE-2010-4478 | 1 Openbsd | 1 Openssh | 2023-11-07 | 7.5 HIGH | N/A |
OpenSSH 5.6 and earlier, when J-PAKE is enabled, does not properly validate the public parameters in the J-PAKE protocol, which allows remote attackers to bypass the need for knowledge of the shared secret, and successfully authenticate, by sending crafted values in each round of the protocol, a related issue to CVE-2010-4252. | |||||
CVE-2009-0537 | 2 Microsoft, Openbsd | 2 Interix, Openbsd | 2023-11-07 | 4.9 MEDIUM | N/A |
Integer overflow in the fts_build function in fts.c in libc in (1) OpenBSD 4.4 and earlier and (2) Microsoft Interix 6.0 build 10.0.6030.0 allows context-dependent attackers to cause a denial of service (application crash) via a deep directory tree, related to the fts_level structure member, as demonstrated by (a) du, (b) rm, (c) chmod, and (d) chgrp on OpenBSD; and (e) SearchIndexer.exe on Vista Enterprise. | |||||
CVE-2008-1147 | 8 Apple, Cosmicperl, Darwin and 5 more | 9 Mac Os X, Mac Os X Server, Directory Pro and 6 more | 2023-11-07 | 6.8 MEDIUM | N/A |
A certain pseudo-random number generator (PRNG) algorithm that uses XOR and 2-bit random hops (aka "Algorithm X2"), as used in OpenBSD 2.6 through 3.4, Mac OS X 10 through 10.5.1, FreeBSD 4.4 through 7.0, and DragonFlyBSD 1.0 through 1.10.1, allows remote attackers to guess sensitive values such as IP fragmentation IDs by observing a sequence of previously generated values. NOTE: this issue can be leveraged for attacks such as injection into TCP packets and OS fingerprinting. | |||||
CVE-2007-6700 | 1 Openbsd | 1 Openbsd | 2023-11-07 | 4.3 MEDIUM | N/A |
Cross-site scripting (XSS) vulnerability in cgi-bin/bgplg in the web interface for the BGPD daemon in OpenBSD 4.1 allows remote attackers to inject arbitrary web script or HTML via the cmd parameter. | |||||
CVE-2005-2666 | 1 Openbsd | 1 Openssh | 2023-11-07 | 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-2004-0492 | 5 Apache, Hp, Ibm and 2 more | 7 Http Server, Virtualvault, Vvos and 4 more | 2023-11-07 | 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-2000-0489 | 3 Freebsd, Netbsd, Openbsd | 3 Freebsd, Netbsd, Openbsd | 2023-11-07 | 2.1 LOW | N/A |
FreeBSD, NetBSD, and OpenBSD allow an attacker to cause a denial of service by creating a large number of socket pairs using the socketpair function, setting a large buffer size via setsockopt, then writing large buffers. | |||||
CVE-2023-35784 | 1 Openbsd | 2 Libressl, Openbsd | 2023-11-06 | N/A | 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-2019-19726 | 1 Openbsd | 1 Openbsd | 2023-10-06 | 7.2 HIGH | 7.8 HIGH |
OpenBSD through 6.6 allows local users to escalate to root because a check for LD_LIBRARY_PATH in setuid programs can be defeated by setting a very small RLIMIT_DATA resource limit. When executing chpass or passwd (which are setuid root), _dl_setup_env in ld.so tries to strip LD_LIBRARY_PATH from the environment, but fails when it cannot allocate memory. Thus, the attacker is able to execute their own library code as root. | |||||
CVE-2023-38283 | 2 Openbgpd, Openbsd | 2 Openbgpd, Openbsd | 2023-09-07 | N/A | 5.3 MEDIUM |
In OpenBGPD before 8.1, incorrect handling of BGP update data (length of path attributes) set by a potentially distant remote actor may cause the system to incorrectly reset a session. This is fixed in OpenBSD 7.3 errata 006. | |||||
CVE-2023-40216 | 1 Openbsd | 1 Openbsd | 2023-08-23 | N/A | 5.5 MEDIUM |
OpenBSD 7.3 before errata 014 is missing an argument-count bounds check in console terminal emulation. This could cause incorrect memory access and a kernel crash after receiving crafted DCS or CSI terminal escape sequences. | |||||
CVE-2016-10009 | 1 Openbsd | 1 Openssh | 2023-07-20 | 7.5 HIGH | 7.3 HIGH |
Untrusted search path vulnerability in ssh-agent.c in ssh-agent in OpenSSH before 7.4 allows remote attackers to execute arbitrary local PKCS#11 modules by leveraging control over a forwarded agent-socket. | |||||
CVE-2021-46880 | 1 Openbsd | 2 Libressl, Openbsd | 2023-05-17 | N/A | 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-2022-48437 | 1 Openbsd | 2 Libressl, Openbsd | 2023-04-21 | N/A | 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-2023-27567 | 1 Openbsd | 1 Openbsd | 2023-04-06 | N/A | 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-2019-14899 | 4 Apple, Freebsd, Linux and 1 more | 8 Ipados, Iphone Os, Mac Os X and 5 more | 2023-03-01 | 4.9 MEDIUM | 7.4 HIGH |
A vulnerability was discovered in Linux, FreeBSD, OpenBSD, MacOS, iOS, and Android that allows a malicious access point, or an adjacent user, to determine if a connected user is using a VPN, make positive inferences about the websites they are visiting, and determine the correct sequence and acknowledgement numbers in use, allowing the bad actor to inject data into the TCP stream. This provides everything that is needed for an attacker to hijack active connections inside the VPN tunnel. |
