CVE-2007-3798 7 Apple, Canonical, Debian and 4 more 8 Mac Os X, Mac Os X Server, Ubuntu Linux and 5 more 2026-04-23 9.8 Critical
Integer overflow in print-bgp.c in the BGP dissector in tcpdump 3.9.6 and earlier allows remote attackers to execute arbitrary code via crafted TLVs in a BGP packet, related to an unchecked return value.
CVE-2009-1935 1 Freebsd 1 Freebsd 2026-04-23 N/A
Integer overflow in the pipe_build_write_buffer function (sys/kern/sys_pipe.c) in the direct write optimization feature in the pipe implementation in FreeBSD 7.1 through 7.2 and 6.3 through 6.4 allows local users to bypass virtual-to-physical address lookups and read sensitive information in memory pages via unspecified vectors.
CVE-2009-1436 1 Freebsd 1 Freebsd 2026-04-23 N/A
The db interface in libc in FreeBSD 6.3, 6.4, 7.0, 7.1, and 7.2-PRERELEASE does not properly initialize memory for Berkeley DB 1.85 database structures, which allows local users to obtain sensitive information by reading a database file.
CVE-2007-4303 2 Cerb, Freebsd 2 Cerbng, Freebsd 2026-04-23 N/A
Multiple race conditions in (1) certain rules and (2) argument copying during VM protection, in CerbNG for FreeBSD 4.8 allow local users to defeat system call interposition and possibly gain privileges or bypass auditing, as demonstrated by modifying command lines in log-exec.cb.
CVE-2008-1146 8 Apple, Cosmicperl, Darwin and 5 more 9 Mac Os X, Mac Os X Server, Directory Pro and 6 more 2026-04-23 N/A
A certain pseudo-random number generator (PRNG) algorithm that uses XOR and 3-bit random hops (aka "Algorithm X3"), as used in OpenBSD 2.8 through 4.2, allows remote attackers to guess sensitive values such as DNS transaction IDs by observing a sequence of previously generated values. NOTE: this issue can be leveraged for attacks such as DNS cache poisoning against OpenBSD's modification of BIND.
CVE-2009-4146 1 Freebsd 1 Freebsd 2026-04-23 N/A
The _rtld function in the Run-Time Link-Editor (rtld) in libexec/rtld-elf/rtld.c in FreeBSD 7.1, 7.2, and 8.0 does not clear the LD_PRELOAD environment variable, which allows local users to gain privileges by executing a setuid or setguid program with a modified LD_PRELOAD variable containing an untrusted search path that points to a Trojan horse library, a different vector than CVE-2009-4147.
CVE-2008-0777 1 Freebsd 1 Freebsd 2026-04-23 N/A
The sendfile system call in FreeBSD 5.5 through 7.0 does not check the access flags of the file descriptor used for sending a file, which allows local users to read the contents of write-only files.
CVE-2006-4516 1 Freebsd 1 Freebsd 2026-04-23 N/A
Integer signedness error in FreeBSD 6.0-RELEASE allows local users to cause a denial of service (memory corruption and kernel panic) via a PT_LWPINFO ptrace command with a large negative data value that satisfies a signed maximum value check but is used in an unsigned copyout function call.
CVE-2006-5824 1 Freebsd 1 Freebsd 2026-04-23 N/A
Integer overflow in the ffs_rdextattr function in FreeBSD 6.1 allows local users to cause a denial of service (kernel panic) and trigger a heap-based buffer overflow via a crafted UFS filesystem, a different vulnerability than CVE-2006-5679. NOTE: a third party states that this issue does not cross privilege boundaries in FreeBSD because only root may mount a filesystem.
CVE-2006-6397 3 Freebsd, Netbsd, Openbsd 3 Freebsd, Netbsd, Openbsd 2026-04-23 N/A
Integer overflow in banner/banner.c in FreeBSD, NetBSD, and OpenBSD might allow local users to modify memory via a long banner. NOTE: CVE and multiple third parties dispute this issue. Since banner is not setuid, an exploit would not cross privilege boundaries in normal operations. This issue is not a vulnerability
CVE-2007-0166 1 Freebsd 1 Freebsd 2026-04-23 N/A
The jail rc.d script in FreeBSD 5.3 up to 6.2 does not verify pathnames when writing to /var/log/console.log during a jail start-up, or when file systems are mounted or unmounted, which allows local root users to overwrite arbitrary files, or mount/unmount files, outside of the jail via a symlink attack.
CVE-2007-3722 1 Freebsd 1 Freebsd 2026-04-23 N/A
The 4BSD process scheduler in the FreeBSD kernel performs scheduling based on CPU billing gathered from periodic process sampling ticks, which allows local users to cause a denial of service (CPU consumption) by performing voluntary nanosecond sleeps that result in the process not being active during a clock interrupt, as described in "Secretly Monopolizing the CPU Without Superuser Privileges."
CVE-2008-4197 5 Freebsd, Linux, Microsoft and 2 more 5 Freebsd, Linux Kernel, Windows and 2 more 2026-04-23 8.8 High
Opera before 9.52 on Windows, Linux, FreeBSD, and Solaris, when processing custom shortcut and menu commands, can produce argument strings that contain uninitialized memory, which might allow user-assisted remote attackers to execute arbitrary code or conduct other attacks via vectors related to activation of a shortcut.
CVE-2006-5550 2 Freebsd, Openbsd 2 Freebsd, Openbsd 2026-04-23 N/A
The kernel in FreeBSD 6.1 and OpenBSD 4.0 allows local users to cause a denial of service via unspecified vectors involving certain ioctl requests to /dev/crypto.
CVE-2006-6013 5 Dragonflybsd, Freebsd, Midnightbsd and 2 more 5 Dragonflybsd, Freebsd, Midnightbsd and 2 more 2026-04-23 N/A
Integer signedness error in the fw_ioctl (FW_IOCTL) function in the FireWire (IEEE-1394) drivers (dev/firewire/fwdev.c) in various BSD kernels, including DragonFlyBSD, FreeBSD 5.5, MidnightBSD 0.1-CURRENT before 20061115, NetBSD-current before 20061116, NetBSD-4 before 20061203, and TrustedBSD, allows local users to read arbitrary memory contents via certain negative values of crom_buf->len in an FW_GCROM command. NOTE: this issue has been labeled as an integer overflow, but it is more like an integer signedness error.
CVE-2009-0601 6 Apple, Freebsd, Linux and 3 more 6 Mac Os X, Freebsd, Linux Kernel and 3 more 2026-04-23 N/A
Format string vulnerability in Wireshark 0.99.8 through 1.0.5 on non-Windows platforms allows local users to cause a denial of service (application crash) via format string specifiers in the HOME environment variable.
CVE-2026-4747 1 Freebsd 1 Freebsd 2026-04-20 8.8 High
Each RPCSEC_GSS data packet is validated by a routine which checks a signature in the packet. This routine copies a portion of the packet into a stack buffer, but fails to ensure that the buffer is sufficiently large, and a malicious client can trigger a stack overflow. Notably, this does not require the client to authenticate itself first. As kgssapi.ko's RPCSEC_GSS implementation is vulnerable, remote code execution in the kernel is possible by an authenticated user that is able to send packets to the kernel's NFS server while kgssapi.ko is loaded into the kernel. In userspace, applications which have librpcgss_sec loaded and run an RPC server are vulnerable to remote code execution from any client able to send it packets. We are not aware of any such applications in the FreeBSD base system.
CVE-2026-3038 1 Freebsd 1 Freebsd 2026-04-16 7.5 High
The rtsock_msg_buffer() function serializes routing information into a buffer. As a part of this, it copies sockaddr structures into a sockaddr_storage structure on the stack. It assumes that the source sockaddr length field had already been validated, but this is not necessarily the case, and it's possible for a malicious userspace program to craft a request which triggers a 127-byte overflow. In practice, this overflow immediately overwrites the canary for the rtsock_msg_buffer() stack frame, resulting in a panic once the function returns. The bug allows an unprivileged user to crash the kernel by triggering a stack buffer overflow in rtsock_msg_buffer(). In particular, the overflow will corrupt a stack canary value that is verified when the function returns; this mitigates the impact of the stack overflow by triggering a kernel panic. Other kernel bugs may exist which allow userspace to find the canary value and thus defeat the mitigation, at which point local privilege escalation may be possible.
CVE-2026-2261 1 Freebsd 1 Freebsd 2026-04-16 7.5 High
Due to a programming error, blocklistd leaks a socket descriptor for each adverse event report it receives. Once a certain number of leaked sockets is reached, blocklistd becomes unable to run the helper script: a child process is forked, but this child dereferences a null pointer and crashes before it is able to exec the helper. At this point, blocklistd still records adverse events but is unable to block new addresses or unblock addresses whose database entries have expired. Once a second, much higher number of leaked sockets is reached, blocklistd becomes unable to receive new adverse event reports. An attacker may take advantage of this by triggering a large number of adverse events from sacrificial IP addresses to effectively disable blocklistd before launching an attack. Even in the absence of attacks or probes by would-be attackers, adverse events will occur regularly in the course of normal operations, and blocklistd will gradually run out file descriptors and become ineffective. The accumulation of open sockets may have knock-on effects on other parts of the system, resulting in a general slowdown until blocklistd is restarted.
CVE-1999-0820 1 Freebsd 1 Freebsd 2026-04-16 N/A
FreeBSD seyon allows users to gain privileges via a modified PATH variable for finding the xterm and seyon-emu commands.
