libgphoto2 is a camera access and control library. Versions up to and including 2.5.33 have an out-of-bounds read in the PTP_DPFF_Enumeration case of ptp_unpack_Sony_DPD() in camlibs/ptp2/ptp-pack.c (line 856). The function reads a 2-byte enumeration count N via dtoh16o(data, *poffset) without verifying that 2 bytes remain in the buffer. The standard ptp_unpack_DPD() at line 704 has this exact check, confirming the Sony variant omitted it by oversight. Commit 3b9f9696be76ae51dca983d9dd8ce586a2561845 fixes the issue.
