  "title": "libgphoto2-6: libgphoto2 is a camera access and control library",
  "description": "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 \u0060ptp_unpack_Sony_DPD()\u0060 in \u0060camlibs/ptp2/ptp-pack.c\u0060 (line 856). The function reads a 2-byte enumeration count N via \u0060dtoh16o(data, *poffset)\u0060 without verifying that 2 bytes remain in the buffer. The standard \u0060ptp_unpack_DPD()\u0060 at line 704 has this exact check, confirming the Sony variant omitted it by oversight. Commit 3b9f9696be76ae51dca983d9dd8ce586a2561845 fixes the issue.",
