CVE-2011-4327 1 Openbsd 1 Openssh 2025-04-11 N/A
ssh-keysign.c in ssh-keysign in OpenSSH before 5.8p2 on certain platforms executes ssh-rand-helper with unintended open file descriptors, which allows local users to obtain sensitive key information via the ptrace system call.
CVE-2011-2168 1 Openbsd 1 Openbsd 2025-04-11 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-2010-4754 4 Apple, Freebsd, Netbsd and 1 more 4 Mac Os X, Freebsd, Netbsd and 1 more 2025-04-11 N/A
The glob implementation in libc in FreeBSD 7.3 and 8.1, NetBSD 5.0.2, and OpenBSD 4.7, and Libsystem in Apple Mac OS X before 10.6.8, allows remote authenticated users to cause a denial of service (CPU and memory consumption) via crafted glob expressions that do not match any pathnames, as demonstrated by glob expressions in STAT commands to an FTP daemon, a different vulnerability than CVE-2010-2632.
CVE-2010-5107 2 Openbsd, Redhat 2 Openssh, Enterprise Linux 2025-04-11 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-2011-0539 1 Openbsd 1 Openssh 2025-04-11 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-2013-4548 1 Openbsd 1 Openssh 2025-04-11 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-2011-1013 3 Linux, Openbsd, Redhat 4 Linux Kernel, Openbsd, Enterprise Linux and 1 more 2025-04-11 N/A
Integer signedness error in the drm_modeset_ctl function in (1) drivers/gpu/drm/drm_irq.c in the Direct Rendering Manager (DRM) subsystem in the Linux kernel before 2.6.38 and (2) sys/dev/pci/drm/drm_irq.c in the kernel in OpenBSD before 4.9 allows local users to trigger out-of-bounds write operations, and consequently cause a denial of service (system crash) or possibly have unspecified other impact, via a crafted num_crtcs (aka vb_num) structure member in an ioctl argument.
CVE-2011-2895 6 Freebsd, Freetype, Netbsd and 3 more 7 Freebsd, Freetype, Netbsd and 4 more 2025-04-11 N/A
The LZW decompressor in (1) the BufCompressedFill function in fontfile/decompress.c in X.Org libXfont before 1.4.4 and (2) compress/compress.c in 4.3BSD, as used in zopen.c in OpenBSD before 3.8, FreeBSD, NetBSD 4.0.x and 5.0.x before 5.0.3 and 5.1.x before 5.1.1, FreeType 2.1.9, and other products, does not properly handle code words that are absent from the decompression table when encountered, which allows context-dependent attackers to trigger an infinite loop or a heap-based buffer overflow, and possibly execute arbitrary code, via a crafted compressed stream, a related issue to CVE-2006-1168 and CVE-2011-2896.
CVE-2008-5161 3 Openbsd, Redhat, Ssh 6 Openssh, Enterprise Linux, Tectia Client and 3 more 2025-04-09 N/A
Error handling in the SSH protocol in (1) SSH Tectia Client and Server and Connector 4.0 through 4.4.11, 5.0 through 5.2.4, and 5.3 through 5.3.8; Client and Server and ConnectSecure 6.0 through 6.0.4; Server for Linux on IBM System z 6.0.4; Server for IBM z/OS 5.5.1 and earlier, 6.0.0, and 6.0.1; and Client 4.0-J through 4.3.3-J and 4.0-K through 4.3.10-K; and (2) OpenSSH 4.7p1 and possibly other versions, when using a block cipher algorithm in Cipher Block Chaining (CBC) mode, makes it easier for remote attackers to recover certain plaintext data from an arbitrary block of ciphertext in an SSH session via unknown vectors.
CVE-2009-0689 6 Freebsd, K-meleon Project, Mozilla and 3 more 9 Freebsd, K-meleon, Firefox and 6 more 2025-04-09 N/A
Array index error in the (1) dtoa implementation in dtoa.c (aka pdtoa.c) and the (2) gdtoa (aka new dtoa) implementation in gdtoa/misc.c in libc, as used in multiple operating systems and products including in FreeBSD 6.4 and 7.2, NetBSD 5.0, OpenBSD 4.5, Mozilla Firefox 3.0.x before 3.0.15 and 3.5.x before 3.5.4, K-Meleon 1.5.3, SeaMonkey 1.1.8, and other products, allows context-dependent attackers to cause a denial of service (application crash) and possibly execute arbitrary code via a large precision value in the format argument to a printf function, which triggers incorrect memory allocation and a heap-based buffer overflow during conversion to a floating-point number.
CVE-2006-5052 2 Openbsd, Redhat 2 Openssh, Enterprise Linux 2025-04-09 N/A
Unspecified vulnerability in portable OpenSSH before 4.4, when running on some platforms, allows remote attackers to determine the validity of usernames via unknown vectors involving a GSSAPI "authentication abort."
CVE-2006-5229 2 Novell, Openbsd 2 Suse Linux, Openssh 2025-04-09 N/A
OpenSSH portable 4.1 on SUSE Linux, and possibly other platforms and versions, and possibly under limited configurations, allows remote attackers to determine valid usernames via timing discrepancies in which responses take longer for valid usernames than invalid ones, as demonstrated by sshtime. NOTE: as of 20061014, it appears that this issue is dependent on the use of manually-set passwords that causes delays when processing /etc/shadow due to an increased number of rounds.
CVE-2009-2904 3 Fedoraproject, Openbsd, Redhat 5 Fedora, Openssh, Enterprise Linux and 2 more 2025-04-09 N/A
A certain Red Hat modification to the ChrootDirectory feature in OpenSSH 4.8, as used in sshd in OpenSSH 4.3 in Red Hat Enterprise Linux (RHEL) 5.4 and Fedora 11, allows local users to gain privileges via hard links to setuid programs that use configuration files within the chroot directory, related to requirements for directory ownership.
CVE-2006-5794 2 Openbsd, Redhat 2 Openssh, Enterprise Linux 2025-04-09 N/A
Unspecified vulnerability in the sshd Privilege Separation Monitor in OpenSSH before 4.5 causes weaker verification that authentication has been successful, which might allow attackers to bypass authentication. NOTE: as of 20061108, it is believed that this issue is only exploitable by leveraging vulnerabilities in the unprivileged process, which are not known to exist.
CVE-2008-4247 3 Freebsd, Netbsd, Openbsd 3 Freebsd, Netbsd, Openbsd 2025-04-09 N/A
ftpd in OpenBSD 4.3, FreeBSD 7.0, NetBSD 4.0, Solaris, and possibly other operating systems interprets long commands from an FTP client as multiple commands, which allows remote attackers to conduct cross-site request forgery (CSRF) attacks and execute arbitrary FTP commands via a long ftp:// URI that leverages an existing session from the FTP client implementation in a web browser.
CVE-2007-1352 8 Mandrakesoft, Openbsd, Redhat and 5 more 14 Mandrake Linux, Mandrake Linux Corporate Server, Mandrake Multi Network Firewall and 11 more 2025-04-09 N/A
Integer overflow in the FontFileInitTable function in X.Org libXfont before 20070403 allows remote authenticated users to execute arbitrary code via a long first line in the fonts.dir file, which results in a heap overflow.
CVE-2007-2242 5 Freebsd, Ietf, Netbsd and 2 more 5 Freebsd, Ipv6, Netbsd and 2 more 2025-04-09 N/A
The IPv6 protocol allows remote attackers to cause a denial of service via crafted IPv6 type 0 route headers (IPV6_RTHDR_TYPE_0) that create network amplification between two routers.
CVE-2009-0537 2 Microsoft, Openbsd 2 Interix, Openbsd 2025-04-09 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-2006-4925 1 Openbsd 1 Openssh 2025-04-09 N/A
packet.c in ssh in OpenSSH allows remote attackers to cause a denial of service (crash) by sending an invalid protocol sequence with USERAUTH_SUCCESS before NEWKEYS, which causes newkeys[mode] to be NULL.
CVE-2008-4109 2 Debian, Openbsd 2 Linux, Openssh 2025-04-09 N/A
A certain Debian patch for OpenSSH before 4.3p2-9etch3 on etch; before 4.6p1-1 on sid and lenny; and on other distributions such as SUSE uses functions that are not async-signal-safe in the signal handler for login timeouts, which allows remote attackers to cause a denial of service (connection slot exhaustion) via multiple login attempts. NOTE: this issue exists because of an incorrect fix for CVE-2006-5051.
