**Name of the Vulnerable Software and Affected Versions** Xpdf version 4.02 **Description** The issue is related to an incorrect subroutine reference in a Type 1C font charstring. This is connected to the `FoFiType1C::getOp()` function, which can lead to stack consumption. **Recommendations** For Xpdf version 4.02, consider restricting the use of Type 1C font charstrings until a patch is available. As a temporary workaround, consider disabling the `FoFiType1C::getOp()` function to minimize the risk of exploitation.
