There is a NULL pointer dereference vulnerability in PSOutputDev::setupResources() located in PSOutputDev.cc in Xpdf 4.01. It can be triggered by sending a crafted pdf file to (for example) the pdftops binary. It allows an attacker to cause Denial of Service (Segmentation fault) or possibly have unspecified other impact.
Weakness
The product dereferences a pointer that it expects to be valid but is NULL.
