1 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.
2 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.
3 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.
4 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.
