Description Andrej Nemec 2016-10-27 08:42:11 UTC 
An exploitable heap based buffer overflow exists in the handling of compressed TIFF images in LibTIFF’s PixarLogDecode api. A crafted TIFF document can lead to a heap based buffer overflow resulting in remote code execution. The vulnerability can be triggered through any user controlled TIFF that is handled by this functionality.

Hi

According to TALOS-2016-0205 the actual CVE ID should be CVE-2016-5875. So is the CVE-2016-5857 alias a typo?

Thanks already for clarification.

Regards,
Salvatore
