libgphoto2 is a camera access and control library
The libgphoto2 camera access and control library has a vulnerability due to unbounded reads in two functions, which can be exploited when accessing camera data. The issue is fixed in a commit after version 2.5.33. Physical access to the camera or device is required for exploitation.
libgphoto2 is a camera access and control library. In versions up to and including 2.5.33, two functions in camlibs/ptp2/ptp-pack.c accept a data pointer but no length parameter, performing unbounded reads. Their callers in ptp_unpack_EOS_events() have xsize available but never pass it, leaving both functions unable to validate reads against the actual buffer boundary. Commit 1817ecead20c2aafa7549dac9619fe38f47b2f53 patches the issue.
Users of libgphoto2 up to version 2.5.33 are at medium risk, particularly those with physical access to camera devices, due to potential exploitation of unbounded read vulnerabilities.
