CVE-2012-0814 | 1 Openbsd | 1 Openssh | 2025-04-11 | 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-2010-5107 | 1 Openbsd | 1 Openssh | 2025-04-11 | 5.0 MEDIUM | N/A |
The default configuration of OpenSSH through 6.1 enforces a fixed time limit between establishing a TCP connection and completing a login, which makes it easier for remote attackers to cause a denial of service (connection-slot exhaustion) by periodically making many new TCP connections. | |||||
CVE-2014-1692 | 1 Openbsd | 1 Openssh | 2025-04-11 | 7.5 HIGH | N/A |
The hash_buffer function in schnorr.c in OpenSSH through 6.4, when Makefile.inc is modified to enable the J-PAKE protocol, does not initialize certain data structures, which might allow remote attackers to cause a denial of service (memory corruption) or have unspecified other impact via vectors that trigger an error condition. | |||||
CVE-2011-5000 | 1 Openbsd | 1 Openssh | 2025-04-11 | 3.5 LOW | N/A |
The ssh_gssapi_parse_ename function in gss-serv.c in OpenSSH 5.8 and earlier, when gssapi-with-mic authentication is enabled, allows remote authenticated users to cause a denial of service (memory consumption) via a large value in a certain length field. NOTE: there may be limited scenarios in which this issue is relevant. | |||||

CVE-2013-4548 | 1 Openbsd | 1 Openssh | 2025-04-11 | 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-2011-0539 | 1 Openbsd | 1 Openssh | 2025-04-11 | 5.0 MEDIUM | N/A |
The key_certify function in usr.bin/ssh/key.c in OpenSSH 5.6 and 5.7, when generating legacy certificates using the -t command-line option in ssh-keygen, does not initialize the nonce field, which might allow remote attackers to obtain sensitive stack memory contents or make it easier to conduct hash collision attacks. | |||||
CVE-2011-0419 | 9 Apache, Apple, Debian and 6 more | 10 Http Server, Portable Runtime, Mac Os X and 7 more | 2025-04-11 | 4.3 MEDIUM | N/A |
Stack consumption vulnerability in the fnmatch implementation in apr_fnmatch.c in the Apache Portable Runtime (APR) library before 1.4.3 and the Apache HTTP Server before 2.2.18, and in fnmatch.c in libc in NetBSD 5.1, OpenBSD 4.8, FreeBSD, Apple Mac OS X 10.6, Oracle Solaris 10, and Android, allows context-dependent attackers to cause a denial of service (CPU and memory consumption) via *? sequences in the first argument, as demonstrated by attacks against mod_autoindex in httpd. | |||||
CVE-2025-26466 | 3 Canonical, Debian, Openbsd | 3 Ubuntu Linux, Debian Linux, Openssh | 2025-04-10 | N/A | 5.9 MEDIUM |
A flaw was found in the OpenSSH package. For each ping packet the SSH server receives, a pong packet is allocated in a memory buffer and stored in a queue of packages. It is only freed when the server/client key exchange has finished. A malicious client may keep sending such packages, leading to an uncontrolled increase in memory consumption on the server side. Consequently, the server may become unavailable, resulting in a denial of service attack. | |||||
CVE-2008-1147 | 8 Apple, Cosmicperl, Darwin and 5 more | 9 Mac Os X, Mac Os X Server, Directory Pro and 6 more | 2025-04-09 | 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. |
