CVSS v3.1
8.8
High
| Vector | AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H |
Name of the Vulnerable Software and Affected Versions
Nitro Pro versions 13.13.2.242 through 13.16.2.300
Description
The issue is related to a code execution problem in the rendering functionality. When a page's contents are drawn and the stroke color is selected from an 'ICCBased' colorspace, the application reads a length from the file and uses it as a loop sentinel for writing data into an object member. This results in a heap-based buffer overflow due to the object member being a buffer of a static size allocated on the heap. A specially crafted document must be loaded by a victim to trigger this issue.
Recommendations
For versions 13.13.2.242 through 13.16.2.300, consider avoiding the use of 'ICCBased' colorspace when drawing page contents until a patch is available.
As a temporary workaround, restrict the loading of specially crafted documents to minimize the risk of exploitation.
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
