CVE-2010-0542 CUPS: texttops unchecked memory allocation failure leading to NULL pointer dereference
Last modified: 2016-03-04 06:02:22 EST
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.
