CVE-2011-0343 3 Freebsd, Hp, Oneidentity 3 Freebsd, Hp-ux, Syslog-ng 2025-04-11 N/A
Balabit syslog-ng 2.0, 3.0, 3.1, 3.2 OSE and PE, when running on FreeBSD or HP-UX, does not properly perform cast operations, which causes syslog-ng to use a default value of -1 to create log files with insecure permissions (07777), which allows local users to read and write to these log files.
CVE-2011-4122 1 Freebsd 1 Freebsd 2025-04-11 N/A
Directory traversal vulnerability in openpam_configure.c in OpenPAM before r478 on FreeBSD 8.1 allows local users to load arbitrary DSOs and gain privileges via a .. (dot dot) in the service_name argument to the pam_start function, as demonstrated by a .. in the -c option to kcheckpass.
CVE-2010-1938 2 Freebsd, Nrl 2 Freebsd, Opie 2025-04-11 N/A
Off-by-one error in the __opiereadrec function in readrec.c in libopie in OPIE 2.4.1-test1 and earlier, as used on FreeBSD 6.4 through 8.1-PRERELEASE and other platforms, allows remote attackers to cause a denial of service (daemon crash) or possibly execute arbitrary code via a long username, as demonstrated by a long USER command to the FreeBSD 8.0 ftpd.
CVE-2013-0211 5 Canonical, Fedoraproject, Freebsd and 2 more 5 Ubuntu Linux, Fedora, Freebsd and 2 more 2025-04-11 N/A
Integer signedness error in the archive_write_zip_data function in archive_write_set_format_zip.c in libarchive 3.1.2 and earlier, when running on 64-bit machines, allows context-dependent attackers to cause a denial of service (crash) via unspecified vectors, which triggers an improper conversion between unsigned and signed types, leading to a buffer overflow.
CVE-2013-4854 10 Fedoraproject, Freebsd, Hp and 7 more 12 Fedora, Freebsd, Hp-ux and 9 more 2025-04-11 N/A
The RFC 5011 implementation in rdata.c in ISC BIND 9.7.x and 9.8.x before 9.8.5-P2, 9.8.6b1, 9.9.x before 9.9.3-P2, and 9.9.4b1, and DNSco BIND 9.9.3-S1 before 9.9.3-S1-P1 and 9.9.4-S1b1, allows remote attackers to cause a denial of service (assertion failure and named daemon exit) via a query with a malformed RDATA section that is not properly handled during construction of a log message, as exploited in the wild in July 2013.
CVE-2013-5209 1 Freebsd 1 Freebsd 2025-04-11 N/A
The sctp_send_initiate_ack function in sys/netinet/sctp_output.c in the SCTP implementation in the kernel in FreeBSD 8.3 through 9.2-PRERELEASE does not properly initialize the state-cookie data structure, which allows remote attackers to obtain sensitive information from kernel stack memory by reading packet data in INIT-ACK chunks.
CVE-2013-5666 1 Freebsd 1 Freebsd 2025-04-11 N/A
The sendfile system-call implementation in sys/kern/uipc_syscalls.c in the kernel in FreeBSD 9.2-RC1 and 9.2-RC2 does not properly pad transmissions, which allows local users to obtain sensitive information (kernel memory) via a length greater than the length of the file.
CVE-2013-5691 1 Freebsd 1 Freebsd 2025-04-11 N/A
The (1) IPv6 and (2) ATM ioctl request handlers in the kernel in FreeBSD 8.3 through 9.2-STABLE do not validate SIOCSIFADDR, SIOCSIFBRDADDR, SIOCSIFDSTADDR, and SIOCSIFNETMASK requests, which allows local users to perform link-layer actions, cause a denial of service (panic), or possibly gain privileges via a crafted application.
CVE-2013-5710 1 Freebsd 1 Freebsd 2025-04-11 N/A
The nullfs implementation in sys/fs/nullfs/null_vnops.c in the kernel in FreeBSD 8.3 through 9.2 allows local users with certain permissions to bypass access restrictions via a hardlink in a nullfs instance to a file in a different instance.
CVE-2013-6832 1 Freebsd 1 Freebsd 2025-04-11 N/A
The nand_ioctl function in sys/dev/nand/nand_geom.c in the nand driver in the kernel in FreeBSD 10 and earlier does not properly initialize a certain data structure, which allows local users to obtain sensitive information from kernel memory via a crafted ioctl call.
CVE-2014-1452 1 Freebsd 1 Freebsd 2025-04-11 N/A
Stack-based buffer overflow in lib/snmpagent.c in bsnmpd, as used in FreeBSD 8.3 through 10.0, allows remote attackers to cause a denial of service (daemon crash) and possibly execute arbitrary code via a crafted GETBULK PDU request.
CVE-2012-3549 1 Freebsd 1 Freebsd 2025-04-11 N/A
The SCTP implementation in FreeBSD 8.2 allows remote attackers to cause a denial of service (NULL pointer dereference and kernel panic) via a crafted ASCONF chunk.
CVE-2012-2143 5 Debian, Freebsd, Php and 2 more 5 Debian Linux, Freebsd, Php and 2 more 2025-04-11 N/A
The crypt_des (aka DES-based crypt) function in FreeBSD before 9.0-RELEASE-p2, as used in PHP, PostgreSQL, and other products, does not process the complete cleartext password if this password contains a 0x80 character, which makes it easier for context-dependent attackers to obtain access via an authentication attempt with an initial substring of the intended password, as demonstrated by a Unicode password.
CVE-2013-2171 1 Freebsd 1 Freebsd 2025-04-11 N/A
The vm_map_lookup function in sys/vm/vm_map.c in the mmap implementation in the kernel in FreeBSD 9.0 through 9.1-RELEASE-p4 does not properly determine whether a task should have write access to a memory location, which allows local users to bypass filesystem write permissions and consequently gain privileges via a crafted application that leverages read permissions, and makes mmap and ptrace system calls.
CVE-2013-3266 1 Freebsd 1 Freebsd 2025-04-11 N/A
The nfsrvd_readdir function in sys/fs/nfsserver/nfs_nfsdport.c in the new NFS server in FreeBSD 8.0 through 9.1-RELEASE-p3 does not verify that a READDIR request is for a directory node, which allows remote attackers to cause a denial of service (memory corruption) or possibly execute arbitrary code by specifying a plain file instead of a directory.
CVE-2019-5598 1 Freebsd 1 Freebsd 2025-04-03 N/A
In FreeBSD 11.3-PRERELEASE before r345378, 12.0-STABLE before r345377, 11.2-RELEASE before 11.2-RELEASE-p10, and 12.0-RELEASE before 12.0-RELEASE-p4, a bug in pf does not check if the outer ICMP or ICMP6 packet has the same destination IP as the source IP of the inner protocol packet allowing a maliciously crafted ICMP/ICMP6 packet could bypass the packet filter rules and be passed to a host that would otherwise be unavailable.
CVE-2022-23087 1 Freebsd 1 Freebsd 2025-03-27 8.8 High
The e1000 network adapters permit a variety of modifications to an Ethernet packet when it is being transmitted. These include the insertion of IP and TCP checksums, insertion of an Ethernet VLAN header, and TCP segmentation offload ("TSO"). The e1000 device model uses an on-stack buffer to generate the modified packet header when simulating these modifications on transmitted packets. When checksum offload is requested for a transmitted packet, the e1000 device model used a guest-provided value to specify the checksum offset in the on-stack buffer. The offset was not validated for certain packet types. A misbehaving bhyve guest could overwrite memory in the bhyve process on the host, possibly leading to code execution in the host context. The bhyve process runs in a Capsicum sandbox, which (depending on the FreeBSD version and bhyve configuration) limits the impact of exploiting this issue.
CVE-2023-0751 1 Freebsd 1 Freebsd 2025-03-25 6.5 Medium
When GELI reads a key file from standard input, it does not reuse the key file to initialize multiple providers at once resulting in the second and subsequent devices silently using a NULL key as the user key file. If a user only uses a key file without a user passphrase, the master key is encrypted with an empty key file allowing trivial recovery of the master key.
CVE-2023-4809 1 Freebsd 1 Freebsd 2025-02-13 7.5 High
In pf packet processing with a 'scrub fragment reassemble' rule, a packet containing multiple IPv6 fragment headers would be reassembled, and then immediately processed. That is, a packet with multiple fragment extension headers would not be recognized as the correct ultimate payload. Instead a packet with multiple IPv6 fragment headers would unexpectedly be interpreted as a fragmented packet, rather than as whatever the real payload is. As a result, IPv6 fragments may bypass pf firewall rules written on the assumption all fragments have been reassembled and, as a result, be forwarded or processed by the host.
CVE-2023-6660 1 Freebsd 1 Freebsd 2025-02-13 6.5 Medium
When a program running on an affected system appends data to a file via an NFS client mount, the bug can cause the NFS client to fail to copy in the data to be written but proceed as though the copy operation had succeeded. This means that the data to be written is instead replaced with whatever data had been in the packet buffer previously. Thus, an unprivileged user with access to an affected system may abuse the bug to trigger disclosure of sensitive information. In particular, the leak is limited to data previously stored in mbufs, which are used for network transmission and reception, and for certain types of inter-process communication. The bug can also be triggered unintentionally by system applications, in which case the data written by the application to an NFS mount may be corrupted. Corrupted data is written over the network to the NFS server, and thus also susceptible to being snooped by other hosts on the network. Note that the bug exists only in the NFS client; the version and implementation of the server has no effect on whether a given system is affected by the problem.
