FreeBSD multiple security vulnerabilities
SecurityVulns ID:13280
Threat Level:
Description:ifioctls privilege escalation, nullfs privilege escalation, sendfile information leakage.
Affected:FREEBSD : FreeBSD 8.4
 FREEBSD : FreeBSD 9.2
CVE:CVE-2013-5710 (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-2013-5691 (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-2013-5666 (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.)
