Apple CUPS is vulnerable to a heap-based buffer overflow, caused by improper bounds checking by the libcups's ppdFindOption() function in ppd-mark.c. By persuading a victim to open a specially crafted ppd file, a remote attacker could overflow a buffer and execute arbitrary code on the system or cause the application to crash.
