BlackBerry Enterprise Server PNG and TIFF Image Processing Vulnerabilities (KB27244)
Critical Nessus Plugin ID 55819
SynopsisThe remote Windows host has an application that is affected by multiple vulnerabilities.
DescriptionThe version of BlackBerry Enterprise Server on the remote host reportedly contains multiple remote code execution vulnerabilities in its image processing library :
- An unspecified error within the BlackBerry MDS Connection Service when processing PNG and TIFF images on a web page being viewed on a BlackBerry smartphone.
- An unspecified error within the BlackBerry Messaging Agent when processing embedded PNG and TIFF images in an email sent to a BlackBerry smartphone.
When the image processing library is used on a specially crafted PNG or TIFF image, an attacker may be able to execute arbitrary code in the context of the BlackBerry Enterprise Server login account.
