K11220361: LibTIFF vulnerability CVE-2015-1547

Security Advisory

Original Publication Date: Sep 14, 2017
Updated Date: Dec 21, 2017

Security Advisory Description

The NeXTDecode function in tif_next.c in LibTIFF allows remote attackers to
cause a denial of service (uninitialized memory access) via a crafted TIFF
image, as demonstrated by libtiff5.tif. (CVE-2015-1547)

Impact

This vulnerability allows a remote attacker to cause a denial-of-service (DoS)
attack. BIG-IP systems that use a BIG-IP AAM or BIG-IP WebAccelerator policy
configured with the Image Optimization settings enabled for TIFF files are
vulnerable to this issue. 

Security Advisory Status

F5 Product Development has assigned ID 642659 (BIG-IP) to this vulnerability.

Security Advisory 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

To mitigate the risk posed by this vulnerability, you can disable image
optimization for TIFF files that use the BIG-IP AAM or BIG-IP WebAccelerator
policy, or ensure that attackers cannot modify TIFF files processed by the
BIG-IP AAM and WebAccelerator systems.

Impact of action: The impact of the suggested mitigation depends on the
specific environment. F5 recommends that you test any such changes during a
maintenance window and consider the possible impact on your specific
environment.

For more information about disabling image optimization, refer to:

  * BIG-IP AAM: The Accelerating Images with Image Optimization chapter of the 
    BIG-IP Acceleration Implementations guide
  * BIG-IP WebAccelerator: The Accelerating Images with Image Optimization
     chapter of the BIG-IP WebAccelerator System Implementations guide
