CVE-2007-1365 1 Openbsd 1 Openbsd 2025-04-09 10.0 HIGH N/A
Buffer overflow in kern/uipc_mbuf2.c in OpenBSD 3.9 and 4.0 allows remote attackers to execute arbitrary code via fragmented IPv6 packets due to "incorrect mbuf handling for ICMP6 packets." NOTE: this was originally reported as a denial of service.
CVE-2007-0343 1 Openbsd 1 Openbsd 2025-04-09 5.0 MEDIUM N/A
OpenBSD before 20070116 allows remote attackers to cause a denial of service (infinite loop and CPU consumption) via certain IPv6 ICMP (aka ICMP6) echo request packets.
CVE-2000-0914 1 Openbsd 1 Openbsd 2025-04-03 5.0 MEDIUM N/A
OpenBSD 2.6 and earlier allows remote attackers to cause a denial of service by flooding the server with ARP requests.
CVE-2001-0268 2 Netbsd, Openbsd 2 Netbsd, Openbsd 2025-04-03 7.2 HIGH N/A
The i386_set_ldt system call in NetBSD 1.5 and earlier, and OpenBSD 2.8 and earlier, when the USER_LDT kernel option is enabled, does not validate a call gate target, which allows local users to gain root privileges by creating a segment call gate in the Local Descriptor Table (LDT) with a target that specifies an arbitrary kernel address.
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-2002-1915 3 Freebsd, Netbsd, Openbsd 3 Freebsd, Netbsd, Openbsd 2025-04-03 2.1 LOW 5.5 MEDIUM
tip on multiple BSD-based operating systems allows local users to cause a denial of service (execution prevention) by using flock() to lock the /var/log/acculog file.
CVE-2003-0955 1 Openbsd 1 Openbsd 2025-04-03 4.6 MEDIUM N/A
OpenBSD kernel 3.3 and 3.4 allows local users to cause a denial of service (kernel panic) and possibly execute arbitrary code in 3.4 via a program with an invalid header that is not properly handled by (1) ibcs2_exec.c in the iBCS2 emulation (compat_ibcs2) or (2) exec_elf.c, which leads to a stack-based buffer overflow.
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-1999-0798 5 Bsdi, Freebsd, Openbsd and 2 more 7 Bsd Os, Freebsd, Openbsd and 4 more 2025-04-03 10.0 HIGH N/A
Buffer overflow in bootpd on OpenBSD, FreeBSD, and Linux systems via a malformed header type.
CVE-2000-0996 1 Openbsd 1 Openbsd 2025-04-03 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-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-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-2003-0028 10 Cray, Freebsd, Gnu and 7 more 13 Unicos, Freebsd, Glibc and 10 more 2025-04-03 7.5 HIGH N/A
Integer overflow in the xdrmem_getbytes() function, and possibly other functions, of XDR (external data representation) libraries derived from SunRPC, including libnsl, libc, glibc, and dietlibc, allows remote attackers to execute arbitrary code via certain integer values in length fields, a different vulnerability than CVE-2002-0391.
CVE-2003-0466 7 Apple, Freebsd, Netbsd and 4 more 8 Mac Os X, Mac Os X Server, Freebsd and 5 more 2025-04-03 10.0 HIGH 9.8 CRITICAL
Off-by-one error in the fb_realpath() function, as derived from the realpath function in BSD, may allow attackers to execute arbitrary code, as demonstrated in wu-ftpd 2.5.0 through 2.6.2 via commands that cause pathnames of length MAXPATHLEN+1 to trigger a buffer overflow, including (1) STOR, (2) RETR, (3) APPE, (4) DELE, (5) MKD, (6) RMD, (7) STOU, or (8) RNTO.
CVE-1999-0303 4 Digital, Netbsd, Openbsd and 1 more 5 Osf 1, Netbsd, Openbsd and 2 more 2025-04-03 4.6 MEDIUM N/A
Buffer overflow in BNU UUCP daemon (uucpd) through long hostnames.
CVE-2004-0106 2 Openbsd, Xfree86 Project 2 Openbsd, X11r6 2025-04-03 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-2002-1345 3 Ncftp Software, Openbsd, Sun 4 Ncftp, Openbsd, Solaris and 1 more 2025-04-03 5.0 MEDIUM N/A
Directory traversal vulnerabilities in multiple FTP clients on UNIX systems allow remote malicious FTP servers to create or overwrite files as the client user via filenames containing /absolute/path or .. (dot dot) sequences.
CVE-2002-0514 1 Openbsd 1 Openbsd 2025-04-03 5.0 MEDIUM N/A
PF in OpenBSD 3.0 with the return-rst rule sets the TTL to 128 in the RST packet, which allows remote attackers to determine if a port is being filtered because the TTL is different than the default TTL.
CVE-1999-0001 3 Bsdi, Freebsd, Openbsd 3 Bsd Os, Freebsd, Openbsd 2025-04-03 5.0 MEDIUM N/A
ip_input.c in BSD-derived TCP/IP implementations allows remote attackers to cause a denial of service (crash or hang) via crafted packets.
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.
