NVD Description

Note: Versions mentioned in the description apply only to the upstream libgphoto2-devel package and not the libgphoto2-devel package as distributed by RHEL. See How to fix? for RHEL:6 relevant fixed versions and status.

libgphoto2 is a camera access and control library. Versions up to and including 2.5.33 have an out-of-bounds read vulnerability in ptp_unpack_OI() in camlibs/ptp2/ptp-pack.c (lines 530–563). The function validates len &lt; PTP_oi_SequenceNumber (i.e., len < 48) but subsequently accesses offsets 48–56, up to 9 bytes beyond the validated boundary, via the Samsung Galaxy 64-bit objectsize detection heuristic. Commit 7c7f515bc88c3d0c4098ac965d313518e0ccbe33 fixes the issue.
