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.
