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 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.
CVE-2008-1058 1 Openbsd 1 Openbsd 2025-04-09 N/A
The tcp_respond function in netinet/tcp_subr.c in OpenBSD 4.1 and 4.2 allows attackers to cause a denial of service (panic) via crafted TCP packets. NOTE: some of these details are obtained from third party information.
CVE-2009-0780 1 Openbsd 1 Openbsd 2025-04-09 N/A
The aspath_prepend function in rde_attr.c in bgpd in OpenBSD 4.3 and 4.4 allows remote attackers to cause a denial of service (application crash) via an Autonomous System (AS) advertisement containing a long AS path.
CVE-2002-0701 2 Freebsd, Openbsd 2 Freebsd, Openbsd 2025-04-03 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-2004-0114 3 Freebsd, Netbsd, Openbsd 3 Freebsd, Netbsd, Openbsd 2025-04-03 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-2004-0083 3 Openbsd, Redhat, Xfree86 Project 4 Openbsd, Enterprise Linux, Linux and 1 more 2025-04-03 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-2001-1244 7 Freebsd, Hp, Linux and 4 more 9 Freebsd, Hp-ux, Vvos and 6 more 2025-04-03 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-2004-2338 1 Openbsd 1 Openbsd 2025-04-03 N/A
OpenBSD 3.3 and 3.4 does not properly parse Accept and Deny rules without netmasks on big-endian 64-bit platforms such as SPARC64, which may allow remote attackers to bypass access restrictions.
CVE-2001-1145 3 Freebsd, Netbsd, Openbsd 3 Freebsd, Netbsd, Openbsd 2025-04-03 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-2003-0955 1 Openbsd 1 Openbsd 2025-04-03 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-2000-0312 1 Openbsd 1 Openbsd 2025-04-03 N/A
cron in OpenBSD 2.5 allows local users to gain root privileges via an argv[] that is not NULL terminated, which is passed to cron's fake popen function.
CVE-2000-0310 1 Openbsd 1 Openbsd 2025-04-03 N/A
IP fragment assembly in OpenBSD 2.4 allows a remote attacker to cause a denial of service by sending a large number of fragmented packets.
CVE-2004-0257 2 Netbsd, Openbsd 2 Netbsd, Openbsd 2025-04-03 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.
CVE-2001-0554 10 Debian, Freebsd, Ibm and 7 more 12 Debian Linux, Freebsd, Aix and 9 more 2025-04-03 N/A
Buffer overflow in BSD-based telnetd telnet daemon on various operating systems allows remote attackers to execute arbitrary commands via a set of options including AYT (Are You There), which is not properly handled by the telrcv function.
CVE-2000-0309 1 Openbsd 1 Openbsd 2025-04-03 N/A
The i386 trace-trap handling in OpenBSD 2.4 with DDB enabled allows a local user to cause a denial of service.
CVE-2002-1420 1 Openbsd 1 Openbsd 2025-04-03 N/A
Integer signedness error in select() on OpenBSD 3.1 and earlier allows local users to overwrite arbitrary kernel memory via a negative value for the size parameter, which satisfies the boundary check as a signed integer, but is later used as an unsigned integer during a data copying operation.
CVE-2004-0416 6 Cvs, Gentoo, Openbsd and 3 more 6 Cvs, Linux, Openbsd and 3 more 2025-04-03 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-2004-0687 5 Openbsd, Redhat, Suse and 2 more 6 Openbsd, Enterprise Linux, Network Satellite and 3 more 2025-04-03 N/A
Multiple stack-based buffer overflows in (1) xpmParseColors in parse.c, (2) ParseAndPutPixels in create.c, and (3) ParsePixels in parse.c for libXpm before 6.8.1 allow remote attackers to execute arbitrary code via a malformed XPM image file.
CVE-2004-0222 1 Openbsd 1 Openbsd 2025-04-03 N/A
Multiple memory leaks in isakmpd in OpenBSD 3.4 and earlier allow remote attackers to cause a denial of service (memory exhaustion) via certain ISAKMP packets, as demonstrated by the Striker ISAKMP Protocol Test Suite.
CVE-2001-1559 1 Openbsd 1 Openbsd 2025-04-03 5.5 Medium
The uipc system calls (uipc_syscalls.c) in OpenBSD 2.9 and 3.0 provide user mode return instead of versus rval kernel mode values to the fdrelease function, which allows local users to cause a denial of service and trigger a null dereference.
