CVE-2010-0542: Null Pointer Dereference

First published: Fri Apr 30 2010(Updated: )

A NULL pointer dereference issue exists in the _WriteProlog function of the texttops image filter. The return value from calloc is not checked. This may lead to a NULL pointer dereference. Since the offset from the pointer at which data is subsequently written is controlled by the user, this issue may lead to application termination or arbitrary code execution.
