K35246595: libarchive vulnerability CVE-2016-5418
Security Advisory
Original Publication Date: Dec 08, 2016
Updated Date: Dec 08, 2016
Vulnerability Description
The sandboxing code in libarchive 3.2.0 and earlier mishandles hardlink archive
entries of non-zero data size, which might allow remote attackers to write to
arbitrary files via a crafted archive file. (CVE-2016-5418)
Impact
BIG-IP
On BIG-IP and VIPRION platforms that are configured to use Virtual Clustered
Multiprocessing (vCMP), an authenticated administrator could upload a specially
crafted ISO file and use that ISO file to create a vCMP guest virtual machine.
A successful attack may allow unauthorized modification of files.
LineRate
This functionality is exposed only to authenticated administrators using the
LineRate Manager GUI, CLI, or REST API when performing a system restore with
a backup file of the LineRate system that has been tampered. A successful
attack may allow unauthorized modification of files.
Security Issue Status
F5 Product Development has assigned ID 624728 (BIG-IP) and LRS-61037 (LineRate)
to this vulnerability.

Vulnerability Recommended Actions
If you are running a version listed in the Versions known to be vulnerable
column, you can eliminate this vulnerability by upgrading to a version listed
in the Versions known to be not vulnerable column. If the table lists only an
older version than what you are currently running, or does not list a
non-vulnerable version, then no upgrade candidate currently exists.
Mitigation
BIG-IP
Ensure that only trusted ISO files are uploaded to BIG-IP systems using vCMP.
LineRate
Only use the restore functionality to restore from backups that are trusted.
