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.
AnalysisAI
Out-of-bounds read in libgphoto2 versions up to 2.5.33 in the PTP protocol parser allows information disclosure and potential denial of service when processing specially crafted camera responses. The vulnerability exists in ptp_unpack_DPV() where UINT128 and INT128 cases advance the buffer offset by 16 bytes without verifying sufficient buffer remains available, potentially exposing adjacent memory. …
