Multiple stack-based buffer overflows in the cff_decoder_parse_charstrings function in the CFF Type2 CharStrings interpreter in cff/cffgload.c in FreeType before 2.4.2, as used in Apple iOS before 4.0.2 on the iPhone and iPod touch and before 3.2.2 on the iPad, allow remote attackers to execute arbitrary code or cause a denial of service (memory corruption) via crafted CFF opcodes in embedded fonts in a PDF document, as demonstrated by JailbreakMe. NOTE: some of these details are obtained from third party information.

(There is total information disclosure, resulting in all system files being revealed.)
(There is a total compromise of system integrity. There is a complete loss of system protection, resulting in the entire system being compromised.)
(There is a total shutdown of the affected resource. The attacker can render the resource completely unavailable.)
(The access conditions are somewhat specialized. Some preconditions must be satistified to exploit)
(Authentication is not required to exploit the vulnerability.)
