**Name of the Vulnerable Software and Affected Versions** xpdf version 4.02 **Description** The issue is related to an infinite recursion in the `Catalog::findDestInTree` function, which can cause a denial of service. This function is part of the xpdf software, used for viewing PDF files. The recursion is uncontrolled, allowing an attacker to exploit the issue and disrupt service. **Recommendations** For xpdf version 4.02, consider disabling the `Catalog::findDestInTree` function as a temporary workaround to prevent potential denial of service attacks until a patch is available.
