Summary
[none]
Details

libgphoto2 is a camera access and control library. Versions up to and including 2.5.33 have an out-of-bounds read in ptp_unpack_DPV() in camlibs/ptp2/ptp-pack.c (lines 622–629). The UINT128 and INT128 cases advance *offset += 16 without verifying that 16 bytes remain in the buffer. The entry check at line 609 only guarantees *offset < total (at least 1 byte available), leaving up to 15 bytes unvalidated. Commit 433bde9888d70aa726e32744cd751d7dbe94379a patches the issue.
