CVSS v3.1 |
| 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. |
| 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. |
| ufs_vnops.c in FreeBSD 6.1 allows local users to cause an unspecified denial of service by calling the ftruncate function on a file type that is not VREG, VLNK or VDIR, which is not defined in POSIX. |
| Multiple integer overflows in libc in NetBSD 4.x, FreeBSD 6.x and 7.x, and probably other BSD and Apple Mac OS platforms allow context-dependent attackers to execute arbitrary code via large values of certain integer fields in the format argument to (1) the strfmon function in lib/libc/stdlib/strfmon.c, related to the GET_NUMBER macro; and (2) the printf function, related to left_prec and right_prec. |
| Opera before 10.00 on Linux, Solaris, and FreeBSD does not properly implement the "INPUT TYPE=file" functionality, which allows remote attackers to trick a user into uploading an unintended file via vectors involving a "dropped file." |
| 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. |
| 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." |
| 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. |
| 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. |
| sys_term.c in telnetd in FreeBSD 7.0-RELEASE and other 7.x versions deletes dangerous environment variables with a method that was valid only in older FreeBSD distributions, which might allow remote attackers to execute arbitrary code by passing a crafted environment variable from a telnet client, as demonstrated by an LD_PRELOAD value that references a malicious library. |
| Stack-based buffer overflow in sys/kern/vfs_mount.c in the kernel in FreeBSD 7.0 and 7.1, when vfs.usermount is enabled, allows local users to gain privileges via a crafted (1) mount or (2) nmount system call, related to copying of "user defined data" in "certain error conditions." |
| 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. |
| 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. |
| The ULE process scheduler in the FreeBSD kernel gives preference to "interactive" processes that perform voluntary sleeps, which allows local users to cause a denial of service (CPU consumption), as described in "Secretly Monopolizing the CPU Without Superuser Privileges." |
| ld.so in FreeBSD, NetBSD, and possibly other BSD distributions does not remove certain harmful environment variables, which allows local users to gain privileges by passing certain environment variables to loading processes. NOTE: this issue has been disputed by a third party, stating that it is the responsibility of the application to properly sanitize the environment |
| 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. |
| 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. |
| The IATA (ata) driver in FreeBSD 6.0 and 8.0, when read access to /dev is available, allows local users to cause a denial of service (kernel panic) via a certain IOCTL request with a large count, which triggers a malloc call with a large value. |
| 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. |
| Integer overflow in the ffs_mountfs function in FreeBSD 6.1 allows local users to cause a denial of service (panic) and possibly execute arbitrary code via a crafted UFS filesystem that causes invalid or large size parameters to be provided to the kmem_alloc function. NOTE: a third party states that this issue does not cross privilege boundaries in FreeBSD because only root may mount a filesystem. |
