CVE-2004-0084 2 Openbsd, Xfree86 Project 2 Openbsd, X11r6 2025-04-03 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-2004-0416 5 Cvs, Gentoo, Openbsd and 2 more 5 Cvs, Linux, Openbsd and 2 more 2025-04-03 10.0 HIGH N/A
Double free vulnerability for the error_prog_name string in CVS 1.12.x through 1.12.8, and 1.11.x through 1.11.16, may allow remote attackers to execute arbitrary code.
CVE-2004-0171 2 Freebsd, Openbsd 2 Freebsd, Openbsd 2025-04-03 5.0 MEDIUM N/A
FreeBSD 5.1 and earlier, and Mac OS X before 10.3.4, allows remote attackers to cause a denial of service (resource exhaustion of memory buffers and system crash) via a large number of out-of-sequence TCP packets, which prevents the operating system from creating new connections.
CVE-2004-0819 1 Openbsd 1 Openbsd 2025-04-03 5.0 MEDIUM N/A
The bridge functionality in OpenBSD 3.4 and 3.5, when running a gateway configured as a bridging firewall with the link2 option for IPSec enabled, allows remote attackers to cause a denial of service (crash) via an ICMP echo (ping) packet.
CVE-1999-1214 5 Bsd, Freebsd, Netbsd and 2 more 5 Bsd, Freebsd, Netbsd and 2 more 2025-04-03 2.1 LOW N/A
The asynchronous I/O facility in 4.4 BSD kernel does not check user credentials when setting the recipient of I/O notification, which allows local users to cause a denial of service by using certain ioctl and fcntl calls to cause the signal to be sent to an arbitrary process ID.
CVE-1999-0305 3 Bsdi, Freebsd, Openbsd 3 Bsd Os, Freebsd, Openbsd 2025-04-03 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-1999-0724 1 Openbsd 1 Openbsd 2025-04-03 4.6 MEDIUM N/A
Buffer overflow in OpenBSD procfs and fdescfs file systems via uio_offset in the readdir() function.
CVE-2000-0092 3 Freebsd, Netbsd, Openbsd 3 Freebsd, Netbsd, Openbsd 2025-04-03 6.2 MEDIUM N/A
The BSD make program allows local users to modify files via a symlink attack when the -j option is being used.
CVE-2001-1244 7 Freebsd, Hp, Linux and 4 more 9 Freebsd, Hp-ux, Vvos and 6 more 2025-04-03 5.0 MEDIUM N/A
Multiple TCP implementations could allow remote attackers to cause a denial of service (bandwidth and CPU exhaustion) by setting the maximum segment size (MSS) to a very small number and requesting large amounts of data, which generates more packets with less TCP-level data that amplify network traffic and consume more server CPU to process.
CVE-2004-1082 8 Apache, Apple, Avaya and 5 more 14 Http Server, Apache Mod Digest Apple, Communication Manager and 11 more 2025-04-03 7.5 HIGH N/A
mod_digest_apple for Apache 1.3.31 and 1.3.32 on Mac OS X Server does not properly verify the nonce of a client response, which allows remote attackers to replay credentials.
CVE-2004-1799 1 Openbsd 1 Openbsd 2025-04-03 7.5 HIGH N/A
PF in certain OpenBSD versions, when stateful filtering is enabled, does not limit packets for a session to the original interface, which allows remote attackers to bypass intended packet filters via spoofed packets to other interfaces.
CVE-2004-0688 4 Openbsd, Suse, X.org and 1 more 4 Openbsd, Suse Linux, X11r6 and 1 more 2025-04-03 7.5 HIGH N/A
Multiple integer overflows in (1) the xpmParseColors function in parse.c, (2) XpmCreateImageFromXpmImage, (3) CreateXImage, (4) ParsePixels, and (5) ParseAndPutPixels for libXpm before 6.8.1 may allow remote attackers to execute arbitrary code via a malformed XPM image file.
CVE-1999-0062 1 Openbsd 1 Openbsd 2025-04-03 7.2 HIGH N/A
The chpass command in OpenBSD allows a local user to gain root access through file descriptor leakage.
CVE-2005-0637 1 Openbsd 1 Openbsd 2025-04-03 5.0 MEDIUM N/A
The copy functions in locore.s such as copyout in OpenBSD 3.5 and 3.6, and possibly other BSD based operating systems, may allow attackers to exceed certain address boundaries and modify kernel memory.
CVE-2000-1208 4 Immunix, Netbsd, Openbsd and 1 more 4 Immunix, Netbsd, Openbsd and 1 more 2025-04-03 7.2 HIGH N/A
Format string vulnerability in startprinting() function of printjob.c in BSD-based lpr lpd package may allow local users to gain privileges via an improper syslog call that uses format strings from the checkremote() call.
CVE-1999-0052 3 Bsdi, Freebsd, Openbsd 3 Bsd Os, Freebsd, Openbsd 2025-04-03 5.0 MEDIUM 7.5 HIGH
IP fragmentation denial of service in FreeBSD allows a remote attacker to cause a crash.
CVE-2001-0402 3 Darren Reed, Freebsd, Openbsd 3 Ipfilter, Freebsd, Openbsd 2025-04-03 7.5 HIGH N/A
IPFilter 3.4.16 and earlier does not include sufficient session information in its cache, which allows remote attackers to bypass access restrictions by sending fragmented packets to a restricted port after sending unfragmented packets to an unrestricted port.
CVE-2002-0701 2 Freebsd, Openbsd 2 Freebsd, Openbsd 2025-04-03 2.1 LOW N/A
ktrace in BSD-based operating systems allows the owner of a process with special privileges to trace the process after its privileges have been lowered, which may allow the owner to obtain sensitive information that the process obtained while it was running with the extra privileges.
CVE-2001-1145 3 Freebsd, Netbsd, Openbsd 3 Freebsd, Netbsd, Openbsd 2025-04-03 6.2 MEDIUM N/A
fts routines in FreeBSD 4.3 and earlier, NetBSD before 1.5.2, and OpenBSD 2.9 and earlier can be forced to change (chdir) into a different directory than intended when the directory above the current directory is moved, which could cause scripts to perform dangerous actions on the wrong directories.
CVE-2004-0083 2 Openbsd, Xfree86 Project 2 Openbsd, X11r6 2025-04-03 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.
