libgphoto2 has OOB read in ptp_unpack_EOS_ImageFormat() and ptp_unpack_EOS_CustomFuncEx() due to missing length parameter in ptp-pack.c

libgphoto2 is a camera access and control library. In versions up to and including 2.5.33, two functions in camlibs/ptp2/ptp-pack.c accept a data pointer but no length parameter, performing unbounded reads. Their callers in ptp_unpack_EOS_events() have xsize available but never pass it, leaving both functions unable to validate reads against the actual buffer boundary. Commit 1817ecead20c2aafa7549dac9619fe38f47b2f53 patches the issue.
