F5 Networks BIG-IP : LibTIFF vulnerability (K11220361)

Medium Nessus Plugin ID 105400


The remote device is missing a vendor-supplied security patch.


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.


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.
