Описание
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.
A flaw was found in libgphoto2, a library for camera access. This out-of-bounds read vulnerability in the ptp_unpack_DPV() function occurs because the software does not properly validate buffer boundaries when handling specific data types. An attacker with physical access to the device could exploit this to potentially disclose sensitive information or cause a denial of service.
