Summary
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.

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the
vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base
model, served locally by ML-Gateway.
They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
