Description
This security bulletin contains information about 1 vulnerability.
1) Resource management error (CVE-ID: CVE-2014-1444)
CWE-ID: CWE-399 - Resource Management Errors
CVSSv4: 4.6 [CVSS:4.0/AV:L/AC:L/AT:N/PR:H/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N]
The vulnerability allows a local #AU# to gain access to sensitive information.
The fst_get_iface function in drivers/net/wan/farsync.c in the Linux kernel before 3.11.7 does not properly initialize a certain data structure, which allows local users to obtain sensitive information from kernel memory by leveraging the CAP_NET_ADMIN capability for an SIOCWANDEV ioctl call.
Remediation
Install update from vendor's website.
