Gonitro: Security Vulnerabilities
An exploitable vulnerability exists in the cross-reference table repairing functionality of Nitro Software, Inc.’s Nitro Pro 13.13.2.242. While searching for an object identifier in a malformed document that is missing from the cross-reference table, the application will save a reference to the object’s cross-reference table entry inside a stack variable. If the referenced object identifier is not found, the application may resize the cross-reference table which can change the scope of its entry. Later when the application tries to reference cross-reference entry via the stack variable, the application will access memory belonging to the recently freed table causing a use-after-free condition. A specially crafted document can be delivered by an attacker and loaded by a victim in order to trigger this vulnerability.

An arbitrary code execution vulnerability exists in the rendering functionality of Nitro Software, Inc.’s Nitro Pro 13.13.2.242. When drawing the contents of a page using colors from an indexed colorspace, the application can miscalculate the size of a buffer when allocating space for its colors. When using this allocated buffer, the application can write outside its bounds and cause memory corruption which can lead to code execution. A specially crafted document must be loaded by a victim in order to trigger this vulnerability.

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.

An exploitable code execution vulnerability exists in the rendering functionality of Nitro Pro 13.13.2.242 and 13.16.2.300. When drawing the contents of a page and selecting the stroke color from an 'ICCBased' colorspace, the application will read a length from the file and use it as a loop sentinel when writing data into the member of an object. Due to the object member being a buffer of a static size allocated on the heap, this can result in a heap-based buffer overflow. A specially crafted document must be loaded by a victim in order to trigger this vulnerability.
