CVE-2003-0681 8 Apple, Gentoo, Hp and 5 more 14 Mac Os X, Mac Os X Server, Linux and 11 more 2018-05-03 7.5 HIGH N/A
A "potential buffer overflow in ruleset parsing" for Sendmail 8.12.9, when using the nonstandard rulesets (1) recipient (2), final, or (3) mailer-specific envelope recipients, has unknown consequences.
CVE-1999-0305 3 Bsdi, Freebsd, Openbsd 3 Bsd Os, Freebsd, Openbsd 2018-05-03 5.0 MEDIUM N/A
The system configuration control (sysctl) facility in BSD based operating systems OpenBSD 2.2 and earlier, and FreeBSD 2.2.5 and earlier, does not properly restrict source routed packets even when the (1) dosourceroute or (2) forwarding variables are set, which allows remote attackers to spoof TCP connections.
CVE-2002-1221 3 Freebsd, Isc, Openbsd 3 Freebsd, Bind, Openbsd 2018-05-03 5.0 MEDIUM N/A
BIND 8.x through 8.3.3 allows remote attackers to cause a denial of service (crash) via SIG RR elements with invalid expiry times, which are removed from the internal BIND database and later cause a null dereference.
CVE-2004-0417 5 Cvs, Gentoo, Openbsd and 2 more 5 Cvs, Linux, Openbsd and 2 more 2018-05-03 5.0 MEDIUM N/A
Integer overflow in the "Max-dotdot" CVS protocol command (serve_max_dotdot) for CVS 1.12.x through 1.12.8, and 1.11.x through 1.11.16, may allow remote attackers to cause a server crash, which could cause temporary data to remain undeleted and consume disk space.
CVE-2003-0688 6 Compaq, Freebsd, Openbsd and 3 more 6 Tru64, Freebsd, Openbsd and 3 more 2018-05-03 5.0 MEDIUM N/A
The DNS map code in Sendmail 8.12.8 and earlier, when using the "enhdnsbl" feature, does not properly initialize certain data structures, which allows remote attackers to cause a denial of service (process crash) via an invalid DNS response that causes Sendmail to free incorrect data.
CVE-2004-0414 5 Cvs, Gentoo, Openbsd and 2 more 5 Cvs, Linux, Openbsd and 2 more 2018-05-03 10.0 HIGH N/A
CVS 1.12.x through 1.12.8, and 1.11.x through 1.11.16, does not properly handle malformed "Entry" lines, which prevents a NULL terminator from being used and may lead to a denial of service (crash), modification of critical program data, or arbitrary code execution.
CVE-2000-0996 1 Openbsd 1 Openbsd 2018-05-03 7.2 HIGH N/A
Format string vulnerability in OpenBSD su program (and possibly other BSD-based operating systems) allows local attackers to gain root privileges via a malformed shell.
CVE-2000-0962 1 Openbsd 1 Openbsd 2018-05-03 5.0 MEDIUM N/A
The IPSEC implementation in OpenBSD 2.7 does not properly handle empty AH/ESP packets, which allows remote attackers to cause a denial of service.
CVE-1999-1225 5 Digital, Linux, Netbsd and 2 more 5 Ultrix, Linux Kernel, Netbsd and 2 more 2017-12-19 5.0 MEDIUM N/A
rpc.mountd on Linux, Ultrix, and possibly other operating systems, allows remote attackers to determine the existence of a file on the server by attempting to mount that file, which generates different error messages depending on whether the file exists or not.
CVE-2002-2092 3 Freebsd, Netbsd, Openbsd 3 Freebsd, Netbsd, Openbsd 2017-12-19 3.7 LOW N/A
Race condition in exec in OpenBSD 4.0 and earlier, NetBSD 1.5.2 and earlier, and FreeBSD 4.4 and earlier allows local users to gain privileges by attaching a debugger to a process before the kernel has determined that the process is setuid or setgid.
CVE-2001-1047 1 Openbsd 1 Openbsd 2017-12-19 1.2 LOW N/A
Race condition in OpenBSD VFS allows local users to cause a denial of service (kernel panic) by (1) creating a pipe in one thread and causing another thread to set one of the file descriptors to NULL via a close, or (2) calling dup2 on a file descriptor in one process, then setting the descriptor to NULL via a close in another process that is created via rfork.
CVE-2017-1000373 1 Openbsd 1 Openbsd 2017-10-24 6.4 MEDIUM 6.5 MEDIUM
The OpenBSD qsort() function is recursive, and not randomized, an attacker can construct a pathological input array of N elements that causes qsort() to deterministically recurse N/4 times. This allows attackers to consume arbitrary amounts of stack memory and manipulate stack memory to assist in arbitrary code execution attacks. This affects OpenBSD 6.1 and possibly earlier versions.
CVE-2004-0084 2 Openbsd, Xfree86 Project 2 Openbsd, X11r6 2017-10-11 10.0 HIGH N/A
Buffer overflow in the ReadFontAlias function in XFree86 4.1.0 to 4.3.0, when using the CopyISOLatin1Lowered function, allows local or remote authenticated users to execute arbitrary code via a malformed entry in the font alias (font.alias) file, a different vulnerability than CVE-2004-0083 and CVE-2004-0106.
CVE-2004-0083 2 Openbsd, Xfree86 Project 2 Openbsd, X11r6 2017-10-11 10.0 HIGH N/A
Buffer overflow in ReadFontAlias from dirfile.c of XFree86 4.1.0 through 4.3.0 allows local users and remote attackers to execute arbitrary code via a font alias file (font.alias) with a long token, a different vulnerability than CVE-2004-0084 and CVE-2004-0106.
CVE-2004-0106 2 Openbsd, Xfree86 Project 2 Openbsd, X11r6 2017-10-11 7.2 HIGH N/A
Multiple unknown vulnerabilities in XFree86 4.1.0 to 4.3.0, related to improper handling of font files, a different set of vulnerabilities than CVE-2004-0083 and CVE-2004-0084.
CVE-2004-0114 3 Freebsd, Netbsd, Openbsd 3 Freebsd, Netbsd, Openbsd 2017-10-10 4.6 MEDIUM N/A
The shmat system call in the System V Shared Memory interface for FreeBSD 5.2 and earlier, NetBSD 1.3 and earlier, and OpenBSD 2.6 and earlier, does not properly decrement a shared memory segment's reference count when the vm_map_find function fails, which could allow local users to gain read or write access to a portion of kernel memory and gain privileges.
CVE-2004-0257 2 Netbsd, Openbsd 2 Netbsd, Openbsd 2017-10-10 5.0 MEDIUM N/A
OpenBSD 3.4 and NetBSD 1.6 and 1.6.1 allow remote attackers to cause a denial of service (crash) by sending an IPv6 packet with a small MTU to a listening port and then issuing a TCP connect to that port.
