| 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 version 13.13.2.242
Description
A vulnerability exists in the cross-reference table repairing functionality. When searching for an object identifier in a malformed document, the application saves 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, changing the scope of its entry. Later, when the application tries to reference the cross-reference entry via the stack variable, it accesses memory belonging to the recently freed table, causing a use-after-free condition. An attacker can deliver a specially crafted document to trigger this issue.
