|---|---|---|---|---|
| CVE-2003-0688 | 6 Compaq, Freebsd, Openbsd and 3 more | 7 Tru64, Freebsd, Openbsd and 4 more | 2026-04-16 | 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-2001-1145 | 3 Freebsd, Netbsd, Openbsd | 3 Freebsd, Netbsd, Openbsd | 2026-04-16 | 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-2004-0221 | 1 Openbsd | 1 Openbsd | 2026-04-16 | N/A |
| isakmpd in OpenBSD 3.4 and earlier allows remote attackers to cause a denial of service (crash) via an ISAKMP packet with a delete payload containing a large number of SPIs, which triggers an out-of-bounds read error, as demonstrated by the Striker ISAKMP Protocol Test Suite. | ||||
| CVE-2002-2188 | 1 Openbsd | 1 Openbsd | 2026-04-16 | N/A |
| OpenBSD before 3.2 allows local users to cause a denial of service (kernel crash) via a call to getrlimit(2) with invalid arguments, possibly due to an integer signedness error. | ||||
| CVE-1999-0062 | 1 Openbsd | 1 Openbsd | 2026-04-16 | N/A |
| The chpass command in OpenBSD allows a local user to gain root access through file descriptor leakage. | ||||
| CVE-1999-0305 | 3 Bsdi, Freebsd, Openbsd | 3 Bsd Os, Freebsd, Openbsd | 2026-04-16 | 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-2003-0078 | 4 Freebsd, Openbsd, Openssl and 1 more | 6 Freebsd, Openbsd, Openssl and 3 more | 2026-04-16 | N/A |
| ssl3_get_record in s3_pkt.c for OpenSSL before 0.9.7a and 0.9.6 before 0.9.6i does not perform a MAC computation if an incorrect block cipher padding is used, which causes an information leak (timing discrepancy) that may make it easier to launch cryptographic attacks that rely on distinguishing between padding and MAC verification errors, possibly leading to extraction of the original plaintext, aka the "Vaudenay timing attack." | ||||
| CVE-2004-0083 | 3 Openbsd, Redhat, Xfree86 Project | 4 Openbsd, Enterprise Linux, Linux and 1 more | 2026-04-16 | 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-2004-0222 | 1 Openbsd | 1 Openbsd | 2026-04-16 | 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-2004-0414 | 6 Cvs, Gentoo, Openbsd and 3 more | 6 Cvs, Linux, Openbsd and 3 more | 2026-04-16 | 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-2004-0417 | 6 Cvs, Gentoo, Openbsd and 3 more | 6 Cvs, Linux, Openbsd and 3 more | 2026-04-16 | 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-2001-1559 | 1 Openbsd | 1 Openbsd | 2026-04-16 | 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. | ||||
| CVE-2004-2338 | 1 Openbsd | 1 Openbsd | 2026-04-16 | 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-2024-43688 | 2 Openbsd, Vixie | 2 Openbsd, Cron | 2026-04-15 | 7.3 High |
| cron/entry.c in vixie cron before 9cc8ab1, as used in OpenBSD 7.4 and 7.5, allows a heap-based buffer underflow and memory corruption. NOTE: this issue was introduced during a May 2023 refactoring. | ||||
| CVE-2025-67901 | 1 Openbsd | 1 Openbsd | 2026-04-15 | 5.3 Medium |
| openrsync through 0.5.0, as used in OpenBSD through 7.8 and on other platforms, allows a client to cause a server SIGSEGV by specifying a length of zero for block data, because the relationship between p->rem and p->len is not checked. | ||||
| CVE-2023-29323 | 2 Openbsd, Opensmtpd | 2 Openbsd, Opensmtpd | 2025-11-04 | 7.8 High |
| ascii_load_sockaddr in smtpd in OpenBSD before 7.1 errata 024 and 7.2 before errata 020, and OpenSMTPD Portable before 7.0.0-portable commit f748277, can abort upon a connection from a local, scoped IPv6 address. | ||||
| CVE-2023-52557 | 1 Openbsd | 1 Openbsd | 2025-10-10 | 7.5 High |
| In OpenBSD 7.3 before errata 016, npppd(8) could crash by a l2tp message which has an AVP (Attribute-Value Pair) with wrong length. | ||||
| CVE-2023-52556 | 1 Openbsd | 1 Openbsd | 2025-10-10 | 6.2 Medium |
| In OpenBSD 7.4 before errata 009, a race condition between pf(4)'s processing of packets and expiration of packet states may cause a kernel panic. | ||||
| CVE-2023-52558 | 1 Openbsd | 1 Openbsd | 2025-10-10 | 7.5 High |
| In OpenBSD 7.4 before errata 002 and OpenBSD 7.3 before errata 019, a network buffer that had to be split at certain length that could crash the kernel after receiving specially crafted escape sequences. | ||||
