CVE-2020-6112 is a high-severity vulnerability rated 7.8/10 on the CVSS scale. An exploitable code execution vulnerability exists in the JPEG2000 Stripe Decoding functionality of Nitro Software, Inc.’s Nitro Pro 13.13.2.242 when decoding sub-samples. While initializing tiles with sub-sample data, the application can miscalculate a pointer for the stripes in the tile which allow for the decoder to write out of-bounds and cause memory corruption. EPSS estimates a 17.09% chance of exploitation in the next 30 days.

Description

An exploitable code execution vulnerability exists in the JPEG2000 Stripe Decoding functionality of Nitro Software, Inc.’s Nitro Pro 13.13.2.242 when decoding sub-samples. While initializing tiles with sub-sample data, the application can miscalculate a pointer for the stripes in the tile which allow for the decoder to write out of-bounds and cause memory corruption. This can result in code execution. A specially crafted image can be embedded inside a PDF and loaded by a victim in order to trigger this vulnerability.
