1 CVE-2013-6834 20 +Info 2013-11-20 2014-03-04
4.9
None Local Low Not required Complete None None
The ql_eioctl function in sys/dev/qlxgbe/ql_ioctl.c in the kernel in FreeBSD 10 and earlier does not validate a certain size parameter, which allows local users to obtain sensitive information from kernel memory via a crafted ioctl call.
2 CVE-2013-6833 20 +Info 2013-11-20 2013-11-24
4.9
None Local Low Not required Complete None None
The qls_eioctl function in sys/dev/qlxge/qls_ioctl.c in the kernel in FreeBSD 10 and earlier does not validate a certain size parameter, which allows local users to obtain sensitive information from kernel memory via a crafted ioctl call.
3 CVE-2013-6832 200 +Info 2013-11-20 2013-11-24
4.9
None Local Low Not required Complete None None
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.
4 CVE-2013-5710 264 Bypass 2013-09-23 2013-10-23
3.7
None Local High Not required Partial Partial Partial
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.
5 CVE-2013-5691 264 DoS +Priv 2013-09-23 2013-10-23
6.9
None Local Medium Not required Complete Complete Complete
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.
6 CVE-2013-5666 200 +Info 2013-09-23 2013-09-25
4.7
None Local Medium Not required Complete None None
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.
7 CVE-2013-5209 200 +Info 2013-08-29 2013-09-11
7.8
None Remote Low Not required Complete None None
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.
8 CVE-2013-4854 DoS 2013-07-29 2014-10-24
7.8
None Remote Low Not required None None Complete
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.
9 CVE-2013-4851 264 Bypass 2013-07-29 2013-08-22
6.4
None Remote Low Not required Partial Partial None
The vfs_hang_addrlist function in sys/kern/vfs_export.c in the NFS server implementation in the kernel in FreeBSD 8.3 and 9.x through 9.1-RELEASE-p5 controls authorization for host/subnet export entries on the basis of group information sent by the client, which allows remote attackers to bypass file permissions on NFS filesystems via crafted requests.
10 CVE-2013-3266 20 DoS Exec Code Mem. Corr. 2013-05-02 2013-11-24
7.5
None Remote Low Not required Partial Partial Partial
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.
11 CVE-2013-3077 189 Overflow +Priv Bypass 2013-08-28 2013-10-07
7.2
None Local Low Not required Complete Complete Complete
Multiple integer overflows in the IP_MSFILTER and IPV6_MSFILTER features in (1) sys/netinet/in_mcast.c and (2) sys/netinet6/in6_mcast.c in the multicast implementation in the kernel in FreeBSD 8.3 through 9.2-PRERELEASE allow local users to bypass intended restrictions on kernel-memory read and write operations, and consequently gain privileges, via vectors involving a large number of source-filter entries.
12 CVE-2013-2171 264 +Priv Bypass 2013-07-01 2013-08-22
6.9
None Local Medium Not required Complete Complete Complete
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.
